Coupling Lenses for VIS-NIR
InnPho’s Fiber-Optic Coupling Lenses are mounted in the industry standard RMS Threaded Mount favored in most laboratories. Transmittance of these AR-AR coated lenses exceeds 96% at the peak wavelength. Performance is diffraction limited when Maximum Beam Diameter is not exceeded; see below.
