Paper Abstract

Laparoscopic and endoscopic instruments for minimally invasive surgery are widely used and developed. Previously, author proposed an optical system for an endoscope operating in the long-wavelength IR spectral range [1] for thermal monitoring of biological tissue during surgery. The system is a sequence of germanium lenses. This paper discusses energy performance of the resulting system. The analysis of the long wave infrared range (LWIR) detectors is presented, absorption and throughput is evaluated. Signal-to-noise ratio of the resulting system is calculated.
