IR Beam
Expanders
 Special Optics IR beam expanders have adjustable lens spacing and use
Zinc Selenide lens elements that enable low insertion loss over a spectral
range from 9.0 to 10.6 microns. We offer both an IR beam
expanders and IR
Variable beam
expander.
Custom orders are welcome for other specific lens needs. To
receive a custom Beam Expander lens quote email or call us at 973-366-7289 and speak to one of our Optical Design specialist.
