The 38-608-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, 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, a type of anti-reflective coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 1.42mm at the edge and 3mm at the center, with an effective focal length (EFL) of 100mm. The radius of curvature for the first surface (R1) is 51.68mm, and the back focal length (BFL) is 92.02mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The YAG-BBAR coating on this lens is a broadband anti-reflection coating that reduces reflection and increases transmission across a wide range of wavelengths. This makes the lens ideal for applications that require high transmission, such as imaging systems, beam delivery systems, and optical instruments.
