Double-Concave Lenses

Double-Concave (DCV) lenses are optical components commonly used to diverge light in various optical systems due to their negative focal length. These lenses have two concave surfaces, making them ideal for applications that require the divergence of incoming light.

DCV lenses find wide applications in industries such as automotive, telecommunications, and entertainment, and can be found in optical instruments such as microscopes and cameras.

At Visopto, we offer a range of DCV lenses with various coatings and substrates to meet the needs of different applications. We provide anti-reflection coatings that cater to a wide range of wavelengths, including UV, visible, and infrared. Additionally, we offer specialized coatings for laser applications, such as 1064 nm, 532 nm, and 355 nm. We have substrates such as BK7, fused silica, and sapphire for different applications.

Our DCV lenses feature high surface accuracy, with less than 0.2 fringe measured at 633nm and finishes of 20-10 scratch-dig per MIL-PRF 13830. We also offer sizes up to 200mm diameter. Our DCV lenses are of the highest quality, and they provide excellent performance and durability.

If you have specific requirements for your optical system, we can also provide customized DCV lenses to meet your specific needs. With Visopto, you can trust that our DCV lenses will provide the high-quality optical performance you need.
