G314322331 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm
The G314322331 is a plano-concave lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. The lens's concave shape, characterized by a radius of curvature of -51.212 mm, results in a negative focal length of -100 mm.
The lens's geometry also includes a center thickness of 1.5 mm, with both the inner and outer radii being zero. This specific lens is designed to operate at a wavelength of 588 nm. It features a Qio AR/RALVIS AOI 45 coating on both the front and back surfaces, which enhances its transmission capabilities and reduces reflection.
This lens is a spherical type, which is a common choice due to its ease of manufacturing and versatility.
