G311204525 12.5 mm Dia. UVFS Double-Convex Lens; EFL=12.5mm 725-1050nm
This is a G311204525 12.5 mm Dia. UVFS Double-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, with a diameter of 12.5 mm, is designed for use in the ultraviolet to near-infrared spectrum, specifically between 725 and 1050 nanometers.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design allows for a high degree of refraction, making it ideal for applications that require the concentration or divergence of light. The lens has an effective focal length (EFL) of 12.5 mm, which is the distance from the center of the lens to the point where the light rays converge or diverge.
The lens is made from UVFS, a type of fused silica, which is known for its excellent optical properties and durability. The base shape of the lens is circular, and it has a thickness of 1 mm at the edge and 4.7 mm at the center.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it more efficient in transmitting light.
