Spectral Domain OCTS Engine
DeepView® OCT Near-Infrared (NIR) Series
BaySpec’s all new DeepView® Fourier or Spectral-Domain (SD) OCT-800 Series Spectral Engine incorporates a high speed digital line scan camera with a robust VPG®-based Spectrograph simultaneously covering multiple wavelengths for precise and rapid optical coherence tomography measurements.
The DeepView® Spectral Engine provides convenience for researchers and OEM users assembling Fourier or spectral-domain optical coherence tomography (SDOCT), white light interferometry (WLI) or VIS-NIR spectroscopy systems. This flat-field spectral analyzer design is based on highly efficient transmission Volume Phase Grating (VPG®) and mounts on an ultra-fast digital line scan camera. The spectral engine accepts single-mode fiber optic inputs and is customizable via grating inserts to match the spectral bandwidth and center wavelength of the users’ light source.
The OCTS 800 Series spectral engine employs a highly efficient Volume Phase Grating (VPG®) as the spectral dispersion element and an ultra-sensitive CMOS detector array as the detection element, thereby providing high-speed parallel processing and continuous spectrum measurements. The signal is spectrally dispersed with the VPG®, and the diffracted field is focused onto the CMOS array detector. The control electronics read out the processed digital signal to extract required information. Both the raw data and the processed data are available to the host.
