Newport offers four different types of Plano-convex lenses ideal for IR applications. Sapphire lenses are extremely hard and durable. AMTIR lens is an economical choice for not very demanding applications. Calcium fluoride lens has an excellent transmission performance between deep UV to Mid IR wavelengths (180nm-8 micron). AR coated Zinc Selenide lenses are good for many applications including IR imaging, experiment/instrument using CO₂ lasers. Zinc selenide and Calcium fluoride lenses are also good to use with femtosecond IR pulses due to its relatively low GVD in this wavelength regime.

Sapphire Lenses

Our SAPX010 and SAPX013 Sapphire lenses are suitable for high power, high-pressure applications, and vacuum or corrosive atmospheres. Sapphire is a single crystal form of alumina, Al₂O₃. The material is extremely hard and resistant to attack by strong acids. It has high compressive strength, a high melting point, and excellent thermal conductivity. Transmission range is from 150 nm to 5 µm.

Zinc Selenide Lenses

Zinc Selenide lenses are an excellent choice of materials for IR lenses for application between 600 nm to 16 microns wavelengths. Its low absorption coefficient makes it a perfect candidate for applications/instruments using C02 lasers. In Mid IR regime it has a very low GVD which makes it suitable for applications using femtosecond IR pulses. The uncoated ZnSe aspheric lenses (ZNPA series) provide diffraction limited focusing performance, making it ideal for focusing the output of a CO₂ laser.

Calcium Fluoride Lenses

Calcium Fluoride lenses are an excellent choice of material for making lenses for UV to Near IR wavelength (180 nm-8 µm). It has a high average transmission and low chromatic aberration compared to various IR materials. In Near IR regime it has a very low GVD which makes it suitable for applications using femtosecond IR pulses.

AMTIR-1 Lenses

Models AMPX010 and AMPX013 are our most economical IR lenses. AMTIR-1 is a synthetic material transmissive in the Near IR to Mid IR range (800 nm to 16 µm). Transmittance is approximately 70% over the entire range.
