DESCRIPTION

The erbium laser is a diode-pumped solid-state DPSS laser that uses erbium-doped (Er³⁺) glass as the gain medium and a semiconductor diode as the pump source. The NATO standard ranging distance is no less than 3 km. The beam divergence angle is 0.6 mrad, featuring concentrated energy and superior beam quality. This ranging module is compactly designed and small in size, with dimensions of 48 × 30.5 × 21 mm and a weight not exceeding 32 g, making it very convenient for installation and integration.

The LRF0308C adopts a UART (TTL_3.3V) communication interface, offers multiple installation options, and supports program updates through the serial port.
