This is a 111-0132E lens, a high-quality optical component sourced from EKSMA Optics. It is a spherical lens with a base shape of a circle, designed for use in a wide range of optical systems. The lens has a diameter of 12.7 mm and a thickness at the edge of 1.7 mm, while the thickness at the center is 2 mm. The effective focal length (EFL) of this lens is 150 mm.
The lens features a double-convex geometry, with the first radius of curvature (R1) being 155.3 mm and the second radius of curvature (R2) being -155.3 mm. This specific curvature allows for precise focusing and manipulation of light. The inner and outer radii are 0, indicating a uniform curvature throughout the lens.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work optimally at a wavelength of 546 nm. The lens does not come with any coating, which means it is uncoated. However, it can be customized with various coatings upon request to enhance its performance in specific applications.
