These Plano-convex lenses are ideal for IR applications. There are offered in four different types of IR materials for a variety of IR tranmission ranges and properties.
- High IR transmission materials
- Plano-convex for focussing applications
- Sapphire, Calcium Floride, Zinc Selenide or AMTIR-1 substrates
Variety of Material Choices for IR Transmission
We offer a wide variety of IR materials capable of supporting most focusing applications.
Plano-Convex Lens Shape for Focusing Light
Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of this lens shape minimizes spherical aberration in situations where the object and image are located at unequal distance from the lens. The optimum case is where the object is placed at infinity with parallel rays entering lens and the final image is a focused point.
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.
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.
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.
