Dubhe (DB-series) spectrometers are designed for the high-resolution, high-sensitivity measurements required by optical coherence tomography (OCT). This new series features a transmissive optical design with an improved integrated body, employing patented alignment mechanism to deliver ultra-high (0.04 nm) optical resolution in the range from 800 – 880nm. It is available in two versions with different CMOS camera max line rates: 80 kHz or 20 kHz.
The DB series uses a transmission grating and a fully transmissive Czerny-Turner optical design to deliver high optical resolution, high sensitivity, low dispersion, and high-speed spectrum response.
