This is the G052116331 model from Qioptiq Photonics, a 12.7 mm diameter Plano-Convex lens made of N-BK7 glass. The lens has an effective focal length (EFL) of 200mm, making it suitable for applications that require a long focal length.
The lens's geometry is characterized by a thickness of 2.8mm at the edge and 3mm at the center. The front surface of the lens has a radius of curvature of 102.92mm, while the back surface is flat. The lens's design is spherical, which is a common choice for its simplicity and wide range of applications.
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, which is particularly beneficial for applications that require high light transmission.
The lens is mounted, which means it is ready to be integrated into an optical system. The vendor, Qioptiq Photonics, is a reputable manufacturer known for its high-quality optical components. According to the vendor's website, the lens is in stock, ensuring quick delivery.
