The 48-330 is a spherical lens with a base shape of circle, sourced from Edmund Optics. This concave-concave lens has a diameter of 25mm and a focal length of -50mm, making it suitable for applications requiring negative focal lengths. The lens's edge thickness measures 5.78mm, while the center thickness is 2.5mm, providing a balanced structure.
The lens is made from fused sil mal-1965, a material known for its optical properties. It is designed to work with a wavelength of 587.6nm, which is within the visible light spectrum. The lens's geometry, including its inner and outer radii, is optimized for its specific application.
The 48-330 lens features UV-AR coating on both the front and back surfaces. This coating, part of Edmund Optics' standard UV curve, enhances the lens's performance in the UV region, specifically between 250 and 425nm. The coating helps reduce unwanted reflections and increases transmission, making it ideal for UV applications.
