SLB-50B-170PIR2 50.0 mm Dia. x 171.1 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-50B-170PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm 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 50.0 mm and a thickness edge of 3.0 mm, ensuring durability and stability. The thickness center measures 6.6 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 171.1 mm, making it suitable for medium to long-range optical systems.

The lens's first radius of curvature (R1) is 176.46 mm, while the second radius (R2) is -176.46 mm, indicating a double-convex design. The back focal length (BFL) is 168.9 mm, which is crucial for determining the position of the lens in an optical system. The inner and outer radii are 0 mm, suggesting a simple and efficient design.

The lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and durability. The coating on both the front and back is opt ir2, which is optimized for the 750-1550nm wavelength range, ensuring high transmission and minimal loss.
