G052302331 6 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-6mm

The G052302331 is a 6 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -6mm. This lens is made from N-BK7, a popular optical glass known for its excellent optical properties, making it suitable for various applications.

The lens's geometry includes a center thickness of 0.5mm, an inner radius of 0mm, and an outer radius of 0mm. The plano-concave shape, characterized by a flat front surface and a curved back surface, is ideal for applications requiring light collimation or reduction of beam divergence.

The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, enhancing its performance in the visible spectrum, particularly at the wavelength of 588nm. This coating provides anti-reflection properties, reducing unwanted reflections and increasing transmission, thereby improving the overall efficiency of the optical system.

The lens is mounted, providing convenience and ease of use. The provided weblink leads to the product page on Qioptiq's website, where users can find more information and can purchase the lens if it's in stock.
