The SBC025AR.16 is a high-quality double-concave lens, designed with a base shape of a circle and a diameter of 25.4 mm. This lens is sourced from the reputable vendor MKS/Newport, and it is currently in stock, as indicated by its weblink status. The lens features a substantial thickness at the edge, measuring 3.45 mm, and a center thickness of 2.5 mm. It has an effective focal length (EFL) of -150 mm, making it suitable for a wide range of optical applications.
The lens's geometry includes a first radius (r1) of -138.092 mm and a second radius (r2) of 138.092 mm, contributing to its double-concave design. The back focal length (BFL) is -150.85 mm, and both the inner and outer radii are 0. The lens is made from UVFS Mal-1965 material, and it is designed to operate at a wavelength of 589 nm.
The SBC025AR.16 is coated with New AR-16 on both the front and back surfaces, enhancing its performance in the near-infrared (NIR) spectrum, specifically between 650 and 1000 nm. This coating ensures high transmission and low reflection, making it an ideal choice for applications that require optimal light transmission.
