This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -500mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.
The lens's geometry includes a center thickness of 1.5mm, an inner radius of 0mm, and an outer radius of 0mm. The plano-concave shape is achieved with a radius of curvature (R1) of -260.39mm on the concave surface.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, enhancing its performance in specific wavelengths, particularly around 588nm. This coating also provides anti-reflection properties, reducing unwanted reflections and increasing transmission.
The lens is mounted, making it ready for immediate use in various applications. The detailed specifications, reliable vendor, and in-stock status make this lens a valuable option for those seeking high-quality, pre-coated optical components.
