UTC Aerospace Systems, a unit of United Technologies, has launched the next-generation Sensors Unlimited shortwave infrared (SWIR) digital line scan camera for spectral domain optical coherence tomography (SD-OCT).
The high-resolution, indium gallium arsenide (InGaAs) SWIR camera will be showcased during SPIE’s BiOS and Photonics West Exhibitions in February.
This camera breaks new ground for SD-OCT when used at the centre wavelengths of 1.05µm, 1.31µm or 1.55µm by delivering A-line rates of >76,000 lps – near the maximum for Base Camera Link interfaces.
With 10µm pitch, the company claims this development achieves the highest optical and spectral resolution available for any InGaAs camera. This pitch also enables ophthalmic OCT instrumentation companies to easily adapt their current 0.84µm SD-OCT spectrometers, which use the same pitch.
The pixel height, or imaging aperture, is 210µm, providing easier alignment for fibre-optic based spectrometers, and high-sensitivity for machine vision applications. A square pixel version will be available in the future.
