MBL-457

Almost every model can be equipped with line generator for uniform line beam. Also the angles of divergence are available at 5°,  7°, 10°, 30°, 45°, 60°, 75°,90°and 100° for custom applications. These series lasers can be used to display a uniform straight reference line for use in alignment, machine vision systems, 3D imaging, construction and process control. 

MDL-457(FC)

Nearly all 457 nm laser modules can be coupled with MM or SM fibers with different core diameters. Here you will find all possible fiber couplings and parameters.

FC-457

The FC-series (Fiber Coupling Laser System) includes laser diode, laser resonator, fiber coupling optics, laser power supply, LD current and crystal temperature control in ONE package. Thanks to its compact dimensions and convenient functions, such as power setting, temperature control, LCD/LED display, etc., it is very well suited for pumping, scientific research, industrial and medical applications.
