GOLDEN, Colo., Dec. 17, 2012 — Ocean Thin Films has introduced the compact PixelCam “snapshot” multispectral cameras for short-wavelength infrared (SWIR) analysis from 700 to 1700 nm. They simultaneously acquire four or more standard and custom spectral bands with a single camera, enabling extraction of spectral information not noticeable with panchromatic SWIR devices. They are used in biomedical imaging, process control, and high-contrast security and surveillance environments.
The cameras combine PixelCam’s precision micropatterned optical coating technology with robust SWIR area sensor cameras manufactured by Sensors Unlimited. High-transmission dichroic filter arrays are aligned directly over corresponding pixels in the imaging array for optimal spectral and spatial resolution. Standard PixelCam cameras are preconfigured with three and four bands, and custom cameras are available with additional application-specific bands.
At the heart of each PixelCam multispectral camera is a custom filter array integrated into a solid-state InGaAs imager with 640 × 512-pixel full resolution. Their sturdy platform provides simultaneous 12-bit Camera Link digital and RS-170 analog outputs and an external trigger. The form factor, frame rates, operating temperature and power requirements are unchanged by the passive spectral filters, facilitating integration into handheld, mobile and aerial devices.
