VISIBLE AND NEAR INFRARED VIDEO SPECTROMETER Russian patent published in 2023 - IPC G01J3/12 

FIELD: spectral measurements.

SUBSTANCE: invention relates to a video spectrometer in the visible and near infrared (IR) ranges of the spectrum. The video spectrometer contains a video camera in the visible and near-IR spectral ranges with a silicon matrix radiation detector, an input lens with a telecentric ray path in image space, an acousto-optic tuneable filter, an output lens with a telecentric ray path in object space, a matching module, a control module for an acousto-optic tuneable filter, and a power supply module with a built-in USB hub. The input lens is configured to construct an intermediate image inside the acousto-optic tuneable filter. The output lens is installed behind the acousto-optic tuneable filter with the possibility of projecting an intermediate image from the acousto-optic tuneable filter to the matrix radiation receiver of the video camera.

EFFECT: reducing the weight and overall dimensions of the device, as well as improving the image quality.
