38-600 18.0mm Dia. x 20.0mm FL; YAG-BBAR Coated; Plano-Convex Lens YAG-BBAR 500-1100nm
This product is a Plano-Convex lens, type of spherical lens, offered by Edmund Optics with a circular base shape. The lens has a diameter of 18.0mm and a thickness at the edge of 1.46mm, while the thickness at the center is 4.3mm. The effective focal length (EFL) of the lens is 20.0mm, and the radius of curvature (R1) is 15.7mm. The back focal length (BFL) is 17.59mm, and both the inner and outer radii are 0mm.
The lens is made of n-sf11 Schott material, a lead-silicate glass with high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens features YAG-BBAR coating on both the front and back surfaces, specifically the EDM YAGBBAR 500-1100 coating, which is designed for use in the 500-1100nm wavelength range. This coating enhances the lens's performance by reducing reflection and increasing transmission.
