The 38-577-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, which is optimized for use within the 500-1100nm range.
The lens's geometry includes a thickness of 1.19mm at the edge and 1.9mm at the center, with an effective focal length (EFL) of 50mm. The radius of curvature for the first surface (R1) is 25.84mm, and the back focal length (BFL) is 48.75mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The YAG-BBAR coating on the lens enhances its performance by reducing reflection and increasing transmission, making it suitable for various applications. The lens's Base Shape is circular, and it is available in stock, according to the vendor's website.
