The SpectraTec II, two wavelength laser module is a highly integrated fiber optic system comprised of two temperature-controlled lasers with individual driving, control, and stability electronics, and one single mode, polarization maintaining fiber optic pigtail output. Beam shaping of the output from the fiber and real-time power feedback module (FFC – Fiber Feedback Collimator) are included. The Fiber Feedback Collimator (FFC) provides precision beam shaping or beam focusing, and real-time power feedback to the control circuits. Power Stability of below 0.5% under normal operating conditions is achieved using this technique.

The system is available with wavelength options ranging from 405 - 980 nm, delivering an output power of up to 50 mW. Custom configurations with various power levels, OEM specific collimation or relay optics, multimode lasers and multimode fibers, and various cabling and fiber connector types are also available.
