The 88-674 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a circular base shape with a diameter of 12.0mm and a thickness of 1.58mm at the edge, increasing to 3.5mm at the center. The effective focal length (EFL) of this lens is 20.0mm, making it suitable for a variety of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material is particularly suitable for applications in the visible spectrum, as indicated by the lens's VIS-EXT coating, which is designed to enhance transmission in the 350-700nm range.
The lens's front and back surfaces are coated with the same VIS-EXT coating, which provides anti-reflection properties and enhances the lens's overall light transmission capabilities. This coating is particularly beneficial in applications where maximum light transmission is required, such as in imaging systems or laser applications.
