SLB-30B-120PIR2 30.0 mm Dia. x 120.6 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-30B-120PIR2 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 30.0 mm and a thickness edge of 2.0 mm, ensuring durability and stability. The thickness center measures 3.8 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 120.6 mm, making it suitable for medium to long-range optical systems.

The first radius of curvature (R1) is 124.56 mm, while the second radius (R2) is -124.56 mm, indicating a double-convex lens design. The back focal length (BFL) is 119.4 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 symmetrical lens design.

The lens is made of 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 ir2 on both the front and back, enhancing its performance in the infrared spectrum.
