Infrared Collimating Lenses

Delivers high numerical aperture for maximum collection efficiency
Provides a compact, single lens design
Supplies diffraction-limited performance
Utilizes high-quality molded LightPath Infrared Lens
RoHS Compliant

MWIR/LWIR collimating lenses have a high numerical aperture for maximum light collection for collimating light from MWIR and LWIR lasers, including quantum cascade lasers (QCL). The aspheric design enables a single lens to replace complex, multiple component optical systems.
