Description

DESCRIPTION

The LDR100 Laser Ranging Target Indicator is a high-precision optoelectronic device designed to measure distance information accurately by emitting a laser beam towards a specific target and calculating the laser's flight time. This innovative Laser Ranging Target Indicator facilitates communication through a reliable RS422 communication interface, boasting exceptional performance and user-friendly operation. Its versatile application across various platforms, including handheld, airborne, and vehicle-mounted systems, is attributed to its compact size, lightweight nature, and low power consumption. Notably, the Laser Ranging Target Indicator operates at a wavelength of 1064nm, and direct exposure to human eyes is strictly prohibited for safety reasons.
