The SLB-30-4000PIR2 is a Plano-Convex Lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 30.0 mm and a focal length of 4000.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties.
The lens features a coating of opt ir2 on both the front and back surfaces, which enhances its performance in the 750-1550nm wavelength range. This coating is designed to improve the lens's durability and optical efficiency, making it an ideal choice for applications that require high-performance lenses.
The geometry of the lens includes a thickness of 2.0 mm at the edge and 2.1 mm at the center. The effective focal length (EFL) is 4000.0 mm, and the back focal length (BFL) is 3998.6 mm. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a curved surface on the other.
