SBC028AR.10 25.4 mm Dia. x -100 mm FL; AR coated; Double-Concave Lens 245-440nm
The SBC028AR.10 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens boasts a base shape of a circle, with a diameter of 25.4 mm and a thickness at the edge of 3.92 mm. The center thickness is 2.5 mm, and it has an effective focal length (EFL) of -100 mm, making it suitable for a wide range of optical applications.
The lens features a unique double-concave geometry, with radii of curvature R1 and R2 being -92.192 mm and 92.192 mm respectively. The back focal length (BFL) is -100.85 mm, and both the inner and outer radii are 0. This specific lens is made from UVFS MAL-1965 material, optimized for use in the wavelength of 589 nm.
The SBC028AR.10 is equipped with a Newport AR-10 coating on both the front and back surfaces. This anti-reflective coating enhances the lens' performance by reducing unwanted reflections and increasing transmission in the spectral range of 245-440 nm. The lens' spherical shape ensures excellent image quality and minimal distortion.
