The Newport LQC1550-05E is a continuous wave laser diode module delivering 5 mW of stable output at 1550 nm. Built on Fabry-Perot architecture, it maintains power stability better than 1% over 8 hours with a spectral linewidth of 1 nm. The module produces an elliptical beam (3.42 × 4.11 mm at 1/e²) with controlled divergence of <1.5 × 0.7 mrad, making it suitable for precision optical applications from spectroscopy to biomedical imaging.

– Compatibility & Integration
External power supply required. Newport recommends the LPMS-5-110 or LPMS-5-220 Series Power Supplies for CDRH compliance, which provide interlock input, key enable switch, delayed start-up, and laser active indication. Warranty coverage applies only when using recommended power supplies. Complete operating instructions are available in the LQx Series Laser Diode Modules User's Manual.
