KBC028AR.33 12.7 mm Dia. x -12.5 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The KBC028AR.33 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use with 1064nm wavelength lasers, making it an ideal choice for a wide range of applications in the fields of optics and photonics.
The lens boasts a diameter of 12.7 mm and a center thickness of 2.5 mm, ensuring a compact and efficient design. The edge thickness is 5.07 mm, providing robustness and durability. The effective focal length (EFL) of this lens is -12.5 mm, indicating its double-concave nature. This EFL value is crucial in determining the lens's focusing power and the size of the beam it will produce.
The KBC028AR.33 is made from N-BK7 Schott glass, a material well-known for its excellent optical properties and versatility. This lens features a new AR-33 coating on both the front and back surfaces, which significantly reduces reflective losses and enhances transmission.
The lens's geometry is spherical, with radii of curvature R1 and R2 being -13.333 mm and 13.333 mm, respectively. These radii contribute to the lens's double-concave shape and its focusing properties. The back focal length (BFL) is -13.29 mm, which is the distance between the lens's rear surface and the focus point.
