SBC019AR.33 25.4 mm Dia. x -250 mm FL; Double-Concave Lens Laser V-Coat 1064nm
This is a high-quality spherical lens, specifically designed for use in laser applications, sourced from the renowned vendor MKS/Newport. The lens boasts a base shape of a circle, with a diameter of 25.4 mm, making it suitable for a wide range of optical systems.
The lens features a double-concave design, with a center thickness of 2.5 mm and an edge thickness of 3.07 mm. This design, combined with an effective focal length (EFL) of -250 mm, ensures excellent optical performance, particularly in focusing or collimating laser beams.
The lens is made from UVFS Mal-1965, a material known for its excellent optical properties and durability. It is coated with a New AR-33 coating on both the front and back surfaces, which enhances its performance in the 1064 nm wavelength range. This coating reduces reflection, increases transmission, and improves the overall efficiency of the optical system.
The lens's inner and outer radii are 0, indicating a symmetrical design that can help minimize optical aberrations. The back focal length (BFL) of -250.85 mm further ensures precise alignment and positioning in the optical system.
