This is a G052403331 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens is spherical in shape, with a base shape of a circle, and is designed for use in a wide range of optical systems.
The lens is made from N-BK7 Schott glass, a popular material known for its excellent optical properties and high damage threshold. It has a diameter of 12.7 mm and a center thickness of 1.5 mm, making it suitable for use in compact optical systems.
The lens features a double-concave geometry, with radii of curvature of -52.33 mm for the first surface and 52.33 mm for the second surface. This geometry results in a negative effective focal length (EFL) of -50 mm, making it ideal for use in systems that require image inversion or reduction.
The lens is coated with Qio Al Ralvis Aoi 45 on both the front and back surfaces. This coating enhances the lens's transmission and reduces its reflectance, improving its performance in a wide range of wavelengths.
The lens is mounted, making it easy to integrate into optical systems. The web link provided in the item data indicates that it is currently in stock, ensuring quick and convenient acquisition for your optical project needs.
