Uncompromising performance

The 785 nm 600 mW Wavelength-Stabilized Fiber Coupled Diode Laser is a high-precision instrument-grade source designed specifically for the most demanding Raman spectroscopy and sensing applications. By utilizing integrated Volume Bragg Grating (VBG) technology, this module achieves an ultra-narrow spectral width of < 0.1 nm and a precisely locked center wavelength of 785 nm ± 0.5 nm. This extreme spectral purity is vital for maximizing signal-to-noise ratios in chemical and material analysis. Built for uncompromising laboratory and medical performance, the K785 series features an internal Thermo-Electric Cooler (TEC) and a 10 kΩ thermistor, ensuring that the wavelength remains locked and stable regardless of ambient environmental fluctuations. Delivering its output through a precision 105 µm fiber core, this module provides the high-brightness beam profile required for technical integration. Housed in a standard industrial 14-pin package with FC termination, it represents the definitive choice for precision medical diagnosis, analytical sensing, and advanced scientific research.
