IsoPlane 81 Spectrograph

Overview

IsoPlane 81 is designed as an easy to use, high performance spectrometer system. Starting with the ingenious opto-mechanical design, there are zero optical aberrations, giving you the highest quality spectral peaks physically possible. Add to this a deeply cooled back illuminated CCD detector with eXcelon and you have an exceptionally sensitive, low noise spectrograph

The IsoPlane 81 cubes simplify complex experimental set-ups allowing rapid experiment design. The standard focus cube f/# matches and focuses light into spectrograph on-axis every time. Optional quick-connect cubes are pre-aligned, contain filters, sample chamber, beamsplitter and fiber ports for either fiber based or free space experiments.

IsoPlane 81 is available with either a standard back illuminated or deep depletion CCD, comes with one cube grating and slit. Options include additional slits, gratings, calibration lamps, lasers and cubes.
