Radiant 355 LD

The Radiant tunable laser series utilizes optical parametric oscillator technology to generate wavelengths over a broad range in the UV, VIS and IR. Integration of system components into one compact unit increases ruggedness, minimizes misalignment and allows the user to reposition the system. Included verification hardware enables the user to confirm beam paths are preserved after shipment or relocation. Hermetically sealed modules protect sensitive optical materials from the environment. All tunable beams exit the system from the same port resulting in one beam path to the end-user’s application. Wavelength tuning is motorized and computer controlled.
