The Newport LQC1310-05E is a self-contained continuous wave (CW) laser diode module delivering stable 5 mW output at 1310 nm. It integrates a laser diode, precision current source, and PID temperature controller into a compact 38.1 mm diameter × 157.5 mm housing. Power stability remains below 1% over 8 hours, making it suitable for demanding optical applications requiring long-term coherence and reliability.
