The Newport LPM1310-05E is a continuous wave laser diode module delivering 5 mW at 1310 nm, designed for direct integration into optical systems requiring stable, precise infrared output. The module operates in Constant Optical Output Power mode, automatically compensating for temperature and focus drift to maintain output stability better than 5% over 8 hours. Output power adjusts from zero to 100% via an onboard potentiometer.

– Compatibility & Integration
Requires 3.5 to 5 VDC supply; Newport LPMS Series power supplies provide CDRH compliance with interlock input, key enable, delayed startup, and laser active indicator. Thermal management via metal mounting fixture is required; heat sink recommended for operation above 25°C or at maximum rated input voltage. Optics cleaning uses compressed air; alcohol and lint-free cloth for residual contamination only. This product is not CE marked.
