G052311525 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-500mm 725-1050nm
This is a 12.7 mm diameter Plano-Concave lens, specifically designed for use in the optical spectrum of 725-1050nm. The lens is mounted and manufactured from N-BK7 Schott glass, a material well-known for its excellent optical properties and wide transparency range.
The lens features a negative focal length (EFL) of -500mm, making it suitable for a variety of applications where light needs to be diverged or focused over a long distance. The lens has a center thickness of 1.5mm, providing a good balance between optical performance and mechanical strength.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the overall performance of the lens in its intended wavelength range.
The lens geometry is spherical, with a radius of curvature of -260.39mm for the concave surface. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
This lens is available from Qioptiq Photonics and is currently in stock, making it an ideal choice for immediate optical system design and development.
