BICV-FS17 25.4 mm Dia. x -500 mm FL; Uncoated; Double-Concave Lens
The BICV-FS17 is a high-precision double-concave lens, characterized by its concave-concave base shape and circular geometry. This lens, sourced from WTS Photonics, boasts a diameter of 25.4 mm and a thickness of 2.35 mm at the edge, tapering down to 2 mm at the center. The effective focal length (EFL) is -500 mm, making it suitable for applications requiring strong negative lensing.
The lens features a double-concave design, with radii of curvature of -460.4 mm for the first surface and 460.4 mm for the second. The back focal length (BFL) is 500.69 mm, and the lens does not have any coating, as indicated by the empty 'coating' field in the item data.
The lens is made of fused silica, specifically the variant with the material ID 'fused sil mal-1965'. This material is known for its excellent transparency across a wide spectral range, making the lens suitable for use with a wavelength of 546.1 nm, as specified in the item data.
The lens is currently in stock and available for immediate purchase, as indicated by the 'weblink status' field in the item data. For more information, users are encouraged to visit the vendor's website via the provided weblink.
