Infrared Lenses are used to collect, focus, or collimate light in the near-infrared, short-wave infrared, mid-wave infrared, or long-wave infrared spectra. IR Lenses are optical lenses that use specific substrates or anti-reflection coatings to maximize performance for applications operating above 700nm including thermal imaging, FLIR, or spectroscopy. The infrared spectrum refers to 700 – 16000nm wavelengths.

With our 1145pcs of test plates inventory from 1.675mm to 30200mm radii, Alkor Technologies can produce prototypes in short time. We only charge very low tooling cost. Ask to receive list of available test plates.

Optical lenses

We offer all types of custom optical lenses and mirrors made from IR and UV materials:

Special size lenses and tooling are available upon request. In addition, we provide a variety of anti-reflecting and reflective coating for infrared optical lenses. Please refer to coating page for more information.

Alkor Technologies Infrared lenses made of Barium Fluoride, Calcium Fluoride, Germanium, Zinc Selenide, Sapphire are ideal for IR applications (2000 nm-16000 nm). Calcium Fluoride (CaF2) lenses can be used for applications requiring high transmission and minimum chromatic aberration between deep UV to Mid IR wavelengths (180 nm-8000 nm). AR coated Zinc Selenide (ZnSe) lenses are good for many applications using near IR to mid IR lights (800 nm-16 µm), and for experiments/instruments using CO2 lasers. Sapphire lenses are particularly good for high pressure and vacuum applications. Zinc Selenide and Calcium fluoride lenses are also good to use with femtosecond IR pulses due to its relatively low group velocity dispersion (GVD) in IR wavelength regime.
