KBC019AR.33 12.7 mm Dia. x -75 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The KBC019AR.33 is a high-quality spherical lens, specifically designed for use in laser systems operating at a wavelength of 1064nm. This lens is sourced from the reputable vendor MKS/Newport and boasts a robust N-BK7 substrate, a common material in optical applications due to its excellent optical properties and versatility.
The lens features a concave-concave base shape, with a diameter of 12.7mm and a thickness of 2.92mm at the edge, tapering down to 2.5mm at the center. This double-concave design results in a back focal length (BFL) of -75.82mm and an effective focal length (EFL) of -75mm, making it suitable for applications requiring precise focusing or collimation of laser beams.
The KBC019AR.33 is coated with a New AR-33 coating on both the front and back surfaces. This anti-reflective coating is specifically designed for use in the infrared region, reducing surface reflections and improving transmission efficiency. The coating ensures optimal performance in laser systems, minimizing losses and enhancing the overall system efficiency.
