NSS-5 Slide Scanner

A laser rangefinder comprises a transmitter module, transmit/receive optics, receiver and signal processing. Development favors greater safety, longer range, higher accuracy, lower power consumption and miniaturization. Common 905nm pulse/phase-ranging sources can damage the retina. Compact, reliable eye-safe 1535nm lasers and 1550nm micropulse all-fiber solid-state lasers are increasingly used. The company supplies integrated eye-safe ranging solutions using Er-glass or micropulse all-fiber solid-state sources. These generate sub-mJ, low-repetition-rate, narrow 1535nm/1550nm pulses, with InGaAs APD detection and TDC time-of-flight measurement for precise distance data.
