Details

UV fused silica double concave (DCV) lenses are biconcave lenses based on fused silica.
UV fused silica glass material has a wider spectral range (185nm-2.1 μ m) than K9 optical glass, excellent transmittance in the UV band, lower refractive index, better uniformity, smaller thermal expansion coefficient, and higher chemical resistance and low fluorescence, which can be used to make various optical elements. A biconcave lens diverges light and has a negative focal length. It consists of two concave surfaces with equal curvature and is commonly used for beam expansion, projection, and enlarging the focal length of optical systems.
The UV fused silica biconcave lens provided by the optical probe intelligence has a variety of sizes and focal lengths of stock standard products, providing a choice of coated and uncoated products. The broadband antireflection film provided can be used in the UV (UV 250-400nm) band to meet your various applications in different scenes and different bands. Guangtan Intelligent can also customize lenses of other specifications according to your actual needs.
