G063073525 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-150mm 725-1050nm
This is a mounted plano-concave lens, type N-BK7, sourced from Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -150mm, making it a negative or diverging lens. This particular lens is designed to operate within the wavelength range of 725-1050nm, which includes the near-infrared spectrum.
The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties, including a high refractive index and low dispersion. This makes it an ideal material for a wide range of optical applications.
The lens features a spherical geometry, with a radius of curvature (R1) of -78.298mm on the concave surface. The inner and outer radii are both zero, indicating a plano surface on the opposite side.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance within its specified wavelength range.
