SLB-15B-25PIR1 15.0 mm Dia. x 25.7 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-15B-25PIR1 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 15.0 mm and a thickness edge of 2.0 mm, ensuring durability and stability. The thickness center measures 4.2 mm, providing a solid foundation for optical systems. The effective focal length (EFL) of this lens is 25.7 mm, making it suitable for a variety of optical applications.

The curvature of the lens is defined by its radii, with r1 at 25.95 mm and r2 at -25.95 mm. This double-convex lens design allows for precise focusing and optimal light transmission. The back focal length (BFL) is 24.3 mm, which is an important factor to consider when designing your optical system.

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, providing enhanced performance and durability. This coating is designed to reduce reflection and increase transmission in the infrared region, making it ideal for applications in this wavelength range.
