G314332400 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm
The G314332400 is a plano-concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular optical glass known for its excellent optical properties and high transmittance in the visible spectrum. The lens features a center thickness of 1.5 mm and an effective focal length (EFL) of -50 mm, making it suitable for applications that require a concave lens.
The lens's geometry includes a radius of curvature (R1) of -26.039 mm for the concave surface. The inner and outer radii are both zero, indicating that the lens has a flat outer surface. The lens's coating includes Qio Silver RAGV 45 on both the front and back surfaces, which enhances its reflective properties and durability.
This lens is designed to operate at a wavelength of 588 nm, which falls within the visible light spectrum. It is spherical in shape, a common geometry for optical lenses due to its ease of manufacturing and versatility. The lens is currently in stock and available for purchase on the Qioptiq Photonics website.
