Model CP 140-3301. Dimensions are in mm and indicative only. Please contact us for full dimensional drawing.

The CP-140 Imaging Spectrograph offers the OEM customer a sturdy, low-cost, f/2, modular instrument, with unsurpassed spatial resolution. High-efficiency, ion-etched, holographic gratings make the CP-140 the perfect spectrograph for use with multiple fibre inputs, linear arrays, and CCD type detectors. Selected gratings cover specific spectral regions from 190 nm to 2500 nm.
