The STA-LTD40M Laser Target Designator features a customized light source architecture. Within a compact and lightweight structure, it delivers stable 40mJ high-energy laser output with a pulse width of ≥10 ns. The initial laser divergence angle is reduced by 50% compared to conventional models, while pointing accuracy is significantly improved.
The product adopts a full-temperature-range, temperature-control-free design. With low standby current, it is well-suited for battery-powered operation and offers excellent endurance. The designator supports special-shaped OEM customization, allowing seamless adaptation to various sizes of electro-optical pods. Additionally, a portable version integrated with human-eye aiming and an OLED high-definition display is optionally available, meeting the needs of both airborne deployment and handheld operation by individual soldiers.
