G052310525 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-200mm 725-1050nm

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 -200mm, making it a negative lens. This particular lens is designed to work within the wavelength range of 725-1050nm, making it suitable for near-infrared applications.

The lens is made of N-BK7, a type of borosilicate glass, which is known for its excellent optical properties and durability. The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, which enhances its performance in the specified wavelength range.

The item data also provides the radii of the curvature for the lens, which are -102.92mm for the first surface and 0mm for the second surface. The lens is mounted, indicating that it is ready for immediate use in optical systems.
