SLB-60B-70PIR2 60.0 mm Dia. x 72.7 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-60B-70PIR2 is a high-quality lens offered by OptoSigma, designed for use in the 750-1550nm wavelength range. This lens, with a diameter of 60.0 mm and a focal length of 72.7 mm, is a Spherical Lens of the Sub Type Spherical Lens (Convex-Convex).
The lens is made from the material n-bk7 schott, a popular choice for its high refractive index and low dispersion. The base shape of the lens is circular, and it features a double-convex geometry. The thickness at the edge of the lens is 3 mm, while the thickness at the center is 16 mm. The effective focal length (EFL) is 72.7 mm, and the back focal length (BFL) is 67.3 mm.
The lens is coated with opt ir2 on both the front and back surfaces, providing excellent anti-reflective properties. This coating is particularly useful in the 750-1550nm wavelength range, reducing unwanted reflections and increasing transmission.
The SLB-60B-70PIR2 is currently in stock and available for immediate purchase from the OptoSigma website. With its high-quality materials, precise geometry, and advanced coating, this lens is an excellent choice for a wide range of optical applications.
