The "Dubhe" series from OtO Photonics is a spectrometer developed for OCT (Optical Coherence Tomography) applications. It has a spectral range of 800 to 880 nm, a body size of 180 (L) x 120 (W) x 63 (H) mm, and a high resolution of 0.04 nm (with a slit width of 5 µm). There are two models available that support CMOS camera line rates of 80 kHz and 20 kHz. It achieves micrometer resolution and captures depths of a few millimeters. This spectrometer is ideal for integration into OCT devices. Please contact us if you would like to evaluate a demo unit.
