SLB-40-60NM 40.0 mm Dia. x -60.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-40-60NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of -60.0 mm. This lens is designed for use within the wavelength range of 400-700nm, 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's geometry includes a thickness edge of 9.3 mm and a thickness center of 2 mm, contributing to its overall design and functionality. The lens's inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other.
The SLB-40-60NM features a coating on both the front and back surfaces. This coating, identified as 'opt m', is designed to enhance the lens's performance and durability. The coating details are not specified in the item data, so it is recommended to contact the vendor for more information on the coating's specific properties and benefits.
