Photonetics 3642HE15 TUNICS-SW TUNABLE LASER SOURCE

The Photonetics 3642HE15 TUNICS-SW is a tunable laser source delivering continuous mode-hop-free operation across the 1460–1595 nm band. Built on an external cavity architecture with invar construction, It has wavelength accuracy to ±0.04 nm and tuning repeatability of ±0.005 nm without requiring temperature stabilization. The integrated wavelength referencing system enables fast, independent wavelength measurement and control, eliminating reliance on external meters.
