The SLB-60B-120PIR1 is a high-quality lens from OptoSigma, designed with a spherical geometry and a base shape of a circle. This lens is a Double-Convex type, featuring two convex surfaces that are curved outwards. The lens has a diameter of 60.0 mm and a focal length of 121.7 mm, making it suitable for a wide range of optical applications.
The lens is made from n-bk7 schott material, a popular choice due to its excellent optical properties and versatility. The geometry of the lens includes a thickness edge of 3.0 mm and a thickness center of 10.3 mm. The effective focal length (EFL) is 121.7 mm, while the back focal length (BFL) is 118.3 mm. The radii of curvature for the first and second surfaces are 124.56 mm and -124.56 mm, respectively.
The SLB-60B-120PIR1 comes with a coating on both the front and back surfaces. The coating is opt ir1, which is specifically designed to enhance the lens' performance in the wavelength range of 633-1064nm. This makes the lens ideal for use in applications that require precise optical performance within this wavelength range.
