SBC025AR.33 25.4 mm Dia. x -150 mm FL; Double-Concave Lens Laser V-Coat 1064nm
This is a high-quality spherical lens from MKS/Newport, designed for use in optical systems that require a concave-concave lens shape. The lens has a diameter of 25.4 mm and a double-concave geometry, with a center thickness of 2.5 mm and an edge thickness of 3.45 mm. The effective focal length (EFL) of the lens is -150 mm, making it suitable for use in systems that require strong negative lensing.
The lens is made from UVFS material, which has a refractive index suitable for use in the visible spectrum. It is coated with a New AR-33 coating on both the front and back surfaces, which is designed to reduce reflection and increase transmission at a wavelength of 1064 nm. This makes it ideal for use in laser systems operating at this wavelength.
The lens is available from the MKS/Newport website, where it is listed as being in stock. The website also provides further technical specifications and datasheets for the lens.
