67-270 25mm Dia. UVFS Aspheric Lens; EFL=20mm; NA=0.63 UV 250-425nm
This is a high-quality aspheric lens from the renowned optical vendor, Edmund Optics. The lens, cataloged under the number 67-270, is a UVFS (UV fused silica) lens with a diameter of 25mm and a numerical aperture (NA) of 0.63. It is designed for use with a wavelength of 587.6nm.
The lens is made from a high-performance fused silica material, specifically syn hpfs7980 corning, which ensures durability and excellent optical performance. The aspheric design of the lens helps to reduce spherical aberration, thereby improving the image quality.
The lens has an effective focal length (EFL) of 20mm, making it suitable for a wide range of optical applications. The inner and outer radii of the lens are 0mm, and the thickness at the edge is 2.27mm. The thickness at the center of the lens is 14mm, providing structural rigidity.
The lens is coated with a UV coating (250-425nm) on both the front and back surfaces, enhancing its transmission capabilities in the ultraviolet range. This makes it ideal for use in UV-based optical systems.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
