SAITIS-640 is one of the smallest long-wave infrared imagers available on the market. SAITIS-640 is based upon a uncooled microbolometer FPA (amorphous silicon, spectral band 8-14 μm) with 640x480 pixels resolution. Unique features for the SAITIS-640 is its low weight and size (from 27mm x 27mm x 26mm) but also the minimum power requirements (1W).
The video output is PAL/NTSC video but also digital video output is available. The camera is controlled via a standard RS-232 interface.

The camera is available with or without integrated shutter for NUC (Non-Uniformity Correction). The shutter-less version, SAITIS-640-X, requires an external shutter to perform the NUC. The camera with integrated shutter, SAITIS-640-S, has an automatic NUC manager integrated for easy-to-use operations.
