The Photonetics Tunics Plus 3642 HE 10 is a tunable external cavity laser source for optical testing, research, and telecommunications. It delivers continuous, mode-hop-free wavelength tuning across approximately 150 nm with 1 pm resolution and adjustable scan speeds from 1 to 100 nm/s. The instrument integrates an internal wavelength referencing system, eliminating the need for external wavelength meters and accelerating test cycles. Output power reaches +10 dBm with ±0.01 dB/h stability and ±0.25 dB flatness during scan. Absolute wavelength accuracy of ±0.04 nm and repeatability of ±0.005 nm (typical) support precision component characterization. Side-mode suppression exceeds 40 dB, while low relative intensity noise (–145 dB/Hz typical) ensures signal integrity in sensitive measurements.
