General Optics
Beam Combiners
Align CO2 and other infrared laser beam delivery systems with these dichroic beamsplitters that transmit IR and reflect HeNe or visible wavelength diode-laser beams.
These plano ZnSe optics simplify the process of aligning infrared optical systems by enabling a precisely collinear visible wavelength laser to be introduced into the beam path.
Standard ZnSe Beam Combiner Selection
Choose from several different diameter standard ZnSe combiners. Custom products on other substrates – including ZnS, and Ge – can be fabricated, as well.
