May 14, 2019

Newest Version of High Definition Spectrometer Covers 200-1100 nm

The high performance, high definition Ocean HDX spectrometer is now available in an extended-range (-XR) version that covers the UV-NIR.   The Ocean HDX-XR has a 25 µm slit and extended-range grating responsive from 200-1100 nm. It delivers exceptional spectral performance, with high throughput, low stray light (>3 AU) and great thermal stability (+/-0.5 pixels).

XR Grating Response

This graph shows the representative XR grating response as reported by the grating manufacturer. Keep in mind the actual response within the setup is a function of various factors including detector response, spectrometer configuration, and the wavelengths and intensity of light entering the optical bench.  


Theoretical response for XR grating used in the Ocean HDX-XR spectrometer. Actual response will vary.
