55 Middlesex Street Unit 210 North Chelmsford MA 01863 t: 978.251.4554 www.cpi.com The Lowell Fabry-Perot Interferometer is a state-of-the-art, observatory-class, ground-based system available at a modest cost. Attributes include vertical mounting, minimized moving parts, simplified pointing system, frequency-stabilized laser, and flat field shuttering, resulting in best possible error reduction. In addition, CPI offers installation services, which may entail carrying the system through first-light into routine operations, with daily data collection and automatic analysis. Computational Physics, Inc. The system § Telecentric optical system, with a 150mm diameter objective lens § Andor DU934 1024 x 1024 scientific imaging camera § Two-mirror servo driven pointing system with stand-alone controller and web interface § ImageTool - data acquisition software § Remote laser calibration system § 19” rack mounted control systems and computer § Technical support for software, including remote login capability Features § Custom design and fabrication § Resonant cavity spacing from 3μm to 6cm § Maximum throughput for a given spectral resolution § Temperature stabilization and pressure pot ◦ Pressure pot with PID controlled pressure servo to maintain proper gas pressure in tuned etalon cavity § 150mm diameter etalon with >80% reflectivity from 550nm - 900nm § Etalon cage with invar contacts to minimize thermal expansion § 0.4nm FWHM 2-cavity interference filter; CWL = 630nm Zonal and meridional winds at Arecibo Observatory Zonal and meridional winds at Millstone Hill Observatory Lowell Fabry-Perot Interferometer List of Services § All instruments delivered complete § All products use a common software, included § Opportunities for training, service and maintenance arrangements, and software updates are available upon request
