ST830E(ST850E) OCT spectrometer

Short Description:

JINSP ST830E/ST850E series spectrometer is dedicated to the OCT system. It is an important device in the spectral domain OCT (SD-OCT) system, which determines important performance indicators such as the imaging speed and the signal-to-noise ratio (SNR fall-off) of the OCT system.
ST830/850E series spectrum realizes wavenumber linear spatial dispersion through special optical path design and directly realizes equal interval sampling of wavenumber on hardware. The acquired interference spectrum can be directly subjected to FFT without a wavenumber resampling algorithm, which greatly reduces the complexity of data processing and improves the signal-to-noise ratio of the system. In addition, this product also adopts volume phase holographic grating (VPH), which has high efficiency and can reach 110dB signal-to-noise ratio in SD-OCT experimental system (7mW light source power, 120kHz line imaging speed), and obtain high-quality OCT/OCTA in vivo biological image.
