SLB-25.4-300PIR2 25.4 mm Dia. x 300.0 mm FL; Coated; Plano-Convex Lens 750-1550nm

The SLB-25.4-300PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 25.4 mm and a focal length of 300 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within the infrared spectrum.

The lens is constructed from n-bk7 schott material, a popular choice due to its high refractive index and low dispersion. This ensures excellent image quality and color correction. The lens has a thickness of 2 mm at the edge and 2.5 mm at the center, providing a robust structure while maintaining a sleek profile.

The front and back surfaces of the lens are coated with Opt IR2, a specialized anti-reflection coating designed for the infrared spectrum. This coating reduces surface reflections, enhancing transmission and improving overall system performance.

The lens is circular in shape, with an inner radius of 0 mm and an outer radius of 0 mm, providing a symmetrical optical path. The effective focal length (EFL) is 300 mm, and the back focal length (BFL) is 298.4 mm, offering a long focal length that can be beneficial in applications requiring high magnification or narrow fields of view.
