38-604-INK 25.4mm Dia. x 35.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-604-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-reflection coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 1.69mm at the edge and 6.9mm at the center, with an effective focal length (EFL) of 35mm. The radius of curvature for the first surface (R1) is 18.09mm, and the back focal length (BFL) is 30.46mm. 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 surface reflections and increases transmission. This coating is designed to operate over a wide range of wavelengths, from 500nm to 1100nm, making it suitable for a variety of applications.
