This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -100mm, making it a negative or diverging lens. This means that it spreads out light rays, causing them to diverge from a single point.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 588nm. It comes with a coating on both the front and back surfaces, specifically the "qio bbar arb2nirnbk7" coating, which is designed to enhance its performance in the 725-1050nm spectral range.
The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows users to integrate it into their systems in a way that best suits their specific needs. The lens's geometry, including its inner and outer radii, is optimized for its specific application.
