G063344331 22.4 mm Dia. UVFS Mounted Double-Concave Lens; EFL=-20mm
This is the G063344331 model from Qioptiq Photonics, a 22.4 mm diameter UVFS mounted double-concave lens with an effective focal length (EFL) of -20mm. The lens is made of UVFS material with the Mal-1965 ID, specifically designed for use at a wavelength of 355nm.
The lens features a unique double-concave geometry, with both the front and back surfaces curved inward. The first radius of curvature (R1) is -20.535mm, while the second radius (R2) is also -20.535mm. This symmetrical design allows for precise control over the light path, making it ideal for applications that require tight beam control.
The lens has a center thickness of 1.5mm, providing a good balance between durability and optical performance. The inner and outer radii are both zero, indicating a simple, circular shape.
The lens is coated with Qio AL RALVIS AOI 45 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.
The lens is mounted on UVFS, ensuring stability and ease of use. According to the vendor, the lens is currently in stock and can be purchased from the Qioptiq Photonics website.
