Product Description

Er glass eye-safe laser

Lasers with emission wavelengths longer than 1.4 m are often called eye-safe”, because light in that wavelength range is strongly absorbed in the eye’s cornea and lens and therefore cannot reach the significantly more sensitive retina. Obviously, the quality eye-safe” depends not only on the emission wavelength, but also on the power level and the optical intensity which can reach the eye. Eye-safe lasers are particularly important in 1535nm-laser-for-ranging-and-radar cases where light needs to be transmitted over substantial distances in open air. Examples are laser rangefinders and free-space optical communications.

1535 solid-state eye-safe laser—Ultra compact eye-safe laser for ranging finder

The wavelength of 1535nm is just in the position of the human eye and the atmospheric window, so it has been widely concerned in the fields of laser ranging and electronic communication. Er,Yb:glass lasers are most commonly used for laser rangefinders with a low pulse repetition rate (less than 10 Hz). Our eye-safe laser have already used in ranging finder and its ranging range is 3-5km with high stability, which applied in Gun aiming and UAV pod.
