Selection Guidelines

When selecting a 1.5 µm point light source, consider wavelength accuracy, required output power, connector format and whether polarization-maintaining fiber is required. For interferometry, LiDAR or sensing applications, pay close attention to noise performance, thermal stability and long-term wavelength drift.

Handling & Maintenance

Maintain clean connectors, avoid tight fiber bends and use recommended low-noise drivers for powering the source. Allow the TEC to stabilize after power-up for consistent performance and follow standard laser safety procedures when working with 1.5 µm infrared light in laboratory or production environments.
