SLB-30-4000PIR1 30.0 mm Dia. x 4000.0 mm FL; Coated; Plano-Convex Lens 633-1064nm

The SLB-30-4000PIR1 is a Plano-Convex Lens, a type of spherical lens, sourced from OptoSigma. This lens has a base shape of a circle and is designed for use with a wavelength of 546.1 nm. The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens has a diameter of 30.0 mm and a thickness at the edge of 2.0 mm, which gradually increases to a thickness at the center of 2.1 mm. The effective focal length (EFL) of the lens is 4000.0 mm, making it suitable for applications that require long focal lengths. The front and back surfaces of the lens are coated with opt ir1, a coating that enhances the lens' performance in the infrared region of the spectrum, specifically between 633 and 1064 nm.

The lens' inner and outer radii are both 0.0 mm, indicating a uniform curvature across the lens surface. The back focal length (BFL) of the lens is 3998.6 mm. This information, along with the EFL, can be used to calculate the lens' magnification and other optical properties.
