395nm-280mW Fiber Receptacle Diode Laser

The UVB-LP series of receptacle laser diode modules are very convenient for implementing into systems and instruments. The receptacle will accept 2.5mm-diameter zirconia ferrule connector for user supplied fiber coupling. It allows the use an optical fiber of any desired length, and allows for easy replacement. We provide the modules with the choice of wavelength ranging from 380nm to 440nm and the output power up to 4W from 105µm core fiber- ideals for Laser Direct Imaging (LDI) in the PCB photolithography process, fluorescence excitation and other applications that require compact package and good coupling efficiency.

LP395-280S operates at 395nm and produces output power of 280mW from 105µm core fiber- ideals for Laser Direct Imaging (LDI) in the PCB photolithography process, fluorescence excitation and other applications that require compact package and good coupling efficiency.
