Avantier manufactures large optical domes in custom sizes, often exceeding 100 mm in diameter, with tailored shapes and material options including BK7, fused silica, sapphire, and others. Domes are engineered for transmission across visible, UV, and infrared wavelengths, protecting sensitive systems with durable, high-clarity optics. Read more...

A ZnSe focus lens is an optical element used in infrared optical systems to focus, collimate or reflect infrared light. ZnSe is widely used in the mid-infrared and far-infrared wavelengths (2-20 microns) due to its excellent light transmission and mechanical properties. Read more...

Comparison of silicon lenses and germanium lenses
Silicon lens: suitable for NIR and MIR, high hardness, good thermal stability, low cost.
Germanium lens: suitable for MIR and FIR, high refractive index, easy to process, but high cost, poor thermal stability. Read more...

Precision thin-film polarizer for high-power lasers, delivering high transmission, linear polarization, and superior damage resistance. Read more...

Fused silica rod lenses are processed from high purity fused silica material and have excellent optical properties. The shape is cylindrical and the length is usually larger than the diameter. Read more...
