The SLB-10B-20PIR1 is a high-quality lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens is a Spherical Lens (Convex-Convex) type, featuring a base shape of Circular for versatile application.
The lens has a diameter of 10.0 mm and a thickness edge of 2.0 mm, ensuring durability and stability. The thickness center measures 3.2 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 20.5 mm, making it suitable for a wide range of applications.
The curvature of the lens is defined by its radii, with r1 at 20.76 mm and r2 at -20.76 mm. These values contribute to the lens's double-convex design, which is ideal for focusing and collimating light. The back focal length (BFL) is 19.5 mm, and both the inner and outer radii are 0 mm, indicating a uniform curvature.
The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. This material ensures excellent image quality and color correction. The lens is coated with opt ir1 on both the front and back, enhancing its performance in the infrared region.
