Two economical but sturdy microscopes CHK2ICHL2 microscopes are powerful laboratory and education tools. Simple enough for even first-time microscope operators to master, they also feature extraordinary operational versatility and the durable, proven design of the best-selling Olympus CH Series. To ensure superior viewing resolution with high contrast, they are equipped with Olympus LB Series objectives, which offer outstanding optical correction right up to the periphery of the field of view.

Sum& image over the entim fieM of view with the popular LB S e t h objectives .Known for excellent resolution and high contrast, the LB Series objectives ensure that the image is always flat and sharply defined across the field of view. @LB Series objectives feature a 45mm parfocal distance ahd long working distances to provide extra convenience for specimen marking. The 40x and 100x objectrves are fitted with a safety spring to protect valuable specimens against inadvertent damage. mSlmuftaneous accommodation of four objectives of dierent magnifications is accomplished with the durable. ball bearing-equipped quadruple revoiving nosepiece.

Observation tubes a@ust to meet tndivMu~I dMbmnces in vision @To compensate for operator eye acuity, the binocular obsrvation tube enables a *5 diopter adjustment as well as interpupillary distance adjustment over a 54-72mm range. Bath controls have graduated markings to allow the operator to quickly retum to optimum settings, a particularty welcome feature in group observation in classroom. aBinocuiar and monocular observation - tubes, inclined at a 4Sa angle. assure comfort with less fatigue over long hours of obse~atim.

Anti-fungus M m e n t ptvtads quality of optical components Fungus is a leading cause of damage to optical components such as objedwes and eyepieces, particularly in tropical regions. The C H W H L 2 have been treated against fungus with an effective anti-fungus method dewdoped by Olyrrtpus. By subjecting the components to a continuous stream of thln, vaporous anti-fungus gas, the treatment inhibits the germination of fungi for a period of over three years (Olympus fidd test). The tightly sealed binocular tubs further protects against fungus by preventing dust or dirt from entering the microscope. (Nd adw In some areas.)

Condenser height displacement for perfect illumination .The condenser allows vertical height ad- justment of 3mm to provide the best illumlnation of the specimen. @The CHK2.CHI-2 microscopes u t i l i an N.A. (Numerical Aperture) 1.25 Abbe mndenser, which features an aperture iris diaphragm incorporating a scale to facilitate easy N.A. adjustment optimized for the objective in use.

Smoother iiocusing with coda1 knobs .Coaxial coarse and fine adjustment knobs allow the operator to easily perform one- handed focus adjustments with both elbows resting on the table. To suit operator preference for a heavy or light knob touch, a tension adjustment ring is provided. .Coarse adjustment range is ZOrnm, with fine adjustment possible over this entire range, enabling rapid, accurate focusing from any position.

Lam, stable, heavy-dufy stags .CHK'/CHK microscopes are equipped with large, 120x1 23mm plain stages. A mechanical stage fitted with coaxial drive control knobs (standard on all models except Model CHL2-F) is provided. Featuring ball-bearing guides, the trawse range is 76mm for the X-axis and 40mm for the Y-axis.
