This is a G063346525 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is mounted on UVFS and has an effective focal length (EFL) of -40mm, making it suitable for applications that require a negative focal length. The lens is designed to work within the wavelength range of 725-1050nm, which includes near-infrared (NIR) and short-wave infrared (SWIR) regions.
The lens is made of UVFS material with the ID 1965, which is known for its excellent optical properties. It has a double-concave geometry, with radii of curvature R1 and R2 being -40.388mm and 40.388mm respectively. The lens does not have an inner or outer radius.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the specified wavelength range by reducing reflection and increasing transmission. The lens's shape is spherical, which is a common geometry for optical lenses due to its ease of manufacturing and good optical performance.
