Know About The OCT Spectrometer

OCT (Optical Coherence Tomography) is a technique employed to drive 3D images of the internal layers and structures of a tissue sample. Optical Coherence Tomography (OCT) is a most successful medical optics technology. This technology offers real time, high resolution transverse images for a variety of biomedical and industrial imaging applications. OCT systems use spectral domain technology that offers improvement over time domain approaches. High speed spectral OCT is used for cancer detection.


OCT Imaging

The spectrometer is the core of optical engines. The spectrometer is made with an integrated dual-line camera, offering superior quantum efficiency and noise performance. The spectrometer accepts single mode fiber optic inputs and customizable via grating inserts to match the spectral bandwidth and center wavelength of the user’s light source.
