Waveplates (retarders) are made from birefringent materials

which introduce a phase difference between the fast and slow

principal axis of the waveplate. The optical axis of waveplate is

parallel to the face. Light incident normal to the surface will be

split to components polarized parallel and perpendicular to the

optical axis with different refractive index and velocity in this

device. The difference in velocities gives rise to a phase shift

which is called retardance. At any specific wavelength the

phase retardance is governed by the thickness of Waveplates.

The standard waveplates we provided include half waveplates

and quarter waveplates, other custom waveplates can also be

provided upon request.

When applying a linearly polarized beam to a half waveplate, it

emerges as a linearly polarized beam but its polarization plane

is rotated with respect to the polarization plane of the input

beam. The rotation of the polarization plane is such that the

angle between the input polar izat ion and the output

polarization is twice the angle between the input polarization

and the waveplate's axis. When applying a circularly polarized

beam, a clockwise circular polarization will transform into a

counter-clockwise circular polarization and vice versa. Half

waveplates are often used as continuously adjustable

polarization rotators and as a variable ratio beamsplitter when

used in conjunction with a polarization beamsplitter cube.

When applying a linearly polarized beam with the polarization

plane aligned at 45deg to the waveplate's principal plane, the

output beam will be circularly polarized. Similarly when

applying a circularly polarized beam to a λ/4 waveplate the

output beam will be linearly polarized. When a quarter

waveplate is double passed, i.e. by mirror reflection, it acts as

a half waveplate and rotates the plane of polarization to a

certain angle. Quarter waveplates are widely used in creating

circular polarization from linear or linear polarization from

circular, ellipsometry, optical pumping, suppressing unwanted

reflection, optical isolation and etc.

Achromatic waveplate is similar to zero order waveplate

except that the two plates are made from different birefringent

crystals. Since the dispersion of the birefringence of two

materials is different, it is possible to specify the retardation

values at a broad wavelength range. So, the retardation will

be less sensitive to wavelength change. In other words, it can

be used at a broadband wavelength range.

Multiple order waveplate means the retardance of a

light path will undergo a certain number of full

wavelength shifts in addition to the fractional design

retardance. The thickness of multi order waveplate is

always around 0.5mm. Compared with zero order

waveplate, multi order waveplate is more sensitive to

wavelength and temperature changes. However, they

are less expensive and widely used in many

applications where the increased sensitivities are not

critical.

Compared with cemented true zero order waveplate, telecom waveplate is only one quartz plate, it is mainly used in

fiber communication. Telecom waveplates are thin & compact waveplates specifically designed to meet the demanding

requirements of fiber communication component. The half-wave plate can be used for rotating the polarization state

while the quarter-wave plate can be used to convert linearly polarized light into a circular polarization state and vice

versa. The half waveplate is about 91μm thick, the quarter waveplate is always not 1/4 wave but 3/4 wave, about

137μm in thickness. These ultra thin waveplate ensures the best temperature bandwidth, angle bandwidth and

wavelength bandwidth. The small size of these waveplates also makes them ideal for reducing the overall package size

of your design. We can provide custom sizes per your request.

Retardation. Half, quarter, or other special? Always, half waveplate is used to rotate the polarization plane,

quarter waveplate is used to change circular polarization to plane polarization or vice vera.

Size and working wavelength. This is important for waveplate. The retardation is different at different

wavelength. It depends on wavelength. Union Optic provides standard wavelength(nm) listed as below,

and other wavelengths can be provided upon request.

Type, the diagram below show the comparison of different types.

Sometimes, the waveplate has unwanted etalon effect, in order to

eliminate this effect, Union Optic offer Wedge Waveplate to solve

this problem. For detailed information, please contact us.

Due to the rotation activity of natural quartz crystal, it also can be

used as polarization rotators so that the plane of input linearly

polarized beam will be rotated at special angle which is determined

by the thickness of quartz crystal. Left-handed and right-handed

rotators can be offered by Union Optic now.

Classic Glan type prisms (PGT, PGM, and PGL Series) suffer

a small, unavoidable loss at the two internal interfaces. This

loss is avoided in the Brewster type (PBI Series) by

presenting the P-polarized transmitted beam to these

interfaces at Brewster's angle. The result is a high power, low

loss polarizer that does not need AR coating. The user

should be aware of two important considerations in the using

of Brewster Polarizer. Firstly, we must use collimated beam

on ly ma in l y as the s t r i ngen t angu la r accep tance

requirement. Secondly, the transmitted beam has a relatively

large displacement with respect to the incident beam, but

they are parallel.

Dichroic Sheet Polarizer


Dichroic Sheet Polarizer

Dichroic sheet polarizer is made of dichroic film sandwiched by two glass plates. When a natural

beam transmits through the dichroic material, one of the orthogonal polarization component of the

beam is strongly absorbed and the other goes out with a weak absorption. So, dichroic sheet

polarizer can be used to convert randomly polarized beam into linearly polarized beam. Compared

with polarizing prisms, dichroic sheet polarizer offers a much bigger size and acceptable angle,

but it can not be used in high power applications.

Quartz Wedge Depolarizer


Quartz Wedge Depolarizer

Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change

the plane polarization into a mix of polarization states by scrambling up the polarization, the result is to change plane

polarized beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarization

sensitive instrument.

Union Optic’s quartz wedge depolarizer consists of two 3° wedges of crystal quartz. Usual wedge depolarizer consists of

one crystal quartz wedge and a compensation fused silica to avoid big beam deviation, but the deviation is also very big for

some precise instruments. Union Optic does not use fused silica plate to compensate the beam deviation, we use a crystal

quartz plate with its optical axis along the propagation direction. Because the depolarizer is constructed by same material,

so the beam deviation can be much better. The usual depolarizer can only be used at narrow band wavelength to avoid the

big beam deviation. With our special design, our depolarizer can be used in a wide range of wavelength and keep the

beam deviation in an acceptable range.

When a beam hits on the depolarizer, there is a variable phase shift across the beam aperture on the wedge, so a

polarized beam can be effectively depolarized. Quartz wedge depolarizer can work well with monochromatic and

broadband light source.Usually we can get better result if we orient the input polarization state 45deg to the optical axis of

the depolarizer. And also the effectiveness of the depolarizer increases with the size of the beam cross-section.

Quartz Lyot Depolarizer

Polarizing Optic ─Quartz Lyot Depolarizer

Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change the

plane polarization into a mix of polarization states by scrambling up the polarization, the result is to change plane polarized

beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarization sensitive

instrument.

Union Optic's quartz Lyot depolarizer converts a polarized beam into a pseudo-random polarized beam. Regarding Linearly

polarized beam from a monochromatic source, the output beam is converted to pseudo-depolarized beam with polarization

state varies spatially. Linearly polarized beam comes from a broadband source which is transmitted through a quartz Lyot

depolarizer will have a polarization that varies spatially as well as with wavelength.Union Optic's quartz Lyot depolarizer

consists of two crystal quartz wedges, the thickness of one is twice of the other. The optical axis of each wedge is in the

plane of aperture, the orientation angle between two optical axes is 45°. The unique design of the quartz Lyot depolarizer

does not require orienting the optical axes of a depolarizer at a specific angle, which is especially useful where the initial

polarization state of the light is unknown or varies with time.

Regarding monochromatic light, we can only get good pseudo-random polarization when the input diameter is bigger than

6mm. The minimum beam diameter requirement comes from that randomization of the output beam's polarization is

achieved by producing a spatial variation when the light hits on the wedge surface. Regarding a broadband source, it does

not have the same beam diameter restriction because of the wavelength dependent retardation and also spatial variation.

Due to the rotation activity of natural quartz crystal, it also can be used as polarization rotators so that

the plane of input linearly polarized beam will be rotated at special angle which is determined by the

thickness of quartz crystal. Left-handed and right-handed rotators can be offered by Union Optic now.

Optical Isolator

Polarizing Optic Optical Isolator─

Optical isolator is a combination of a polarization Beamsplitter cube (PBS) and a quarter

waveplate made of crystal quartz. Incident light is linearly polarized by PBS and converted to

circular polarization by the quarter waveplate. If any portion of the emerging beam is reflected

back into the isolator, the quarter waveplate will convert the reflected beam into a linearly

polarized beam which is perpendicular to the input beam. This beam is then blocked by PBS and

it will not return to the input side of the system.

Lateral Displacement Polarization Beamsplitter

Polarizing Optic─

Lateral Displacement Polarization Beamsplitter

Lateral displacement polarization Beamsplitter produces

two parallel output beams which are separated by a lateral

displacement. And the displacement is decided by the size of

rhomboid prism. This Beamsplitter consists of one or two

rhomboid prisms cemented to a right angle prism, and

sometimes we can add a waveplate to manage the

polarization state of the output beams. By using high

precision prisms, we can ensure the parallelism between

input and output beams within 30 arc seconds. And all

entrances feature a multi layer anti-reflection coating.
