KBC082AR.33 50.8 mm Dia. x -100 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The KBC082AR.33 is a high-quality double-concave lens, designed with a diameter of 50.8 mm and a focal length of -100 mm. This lens is sourced from the reputable vendor, MKS/Newport, and is available for immediate purchase from their website.
The lens is constructed from the material n-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties. The lens features a double-concave shape, with radii of curvature of -103.785 mm and 103.785 mm for the front and back surfaces, respectively. This shape is designed to diverge light, making it ideal for use in applications such as beam expansion or collimation.
The KBC082AR.33 is coated with a new AR-33 coating on both the front and back surfaces. This coating is specifically designed for use with a wavelength of 589 nm, providing superior anti-reflective properties. The coating ensures minimal loss of light due to reflection, enhancing the overall efficiency of your optical system.
The lens has a thickness of 7.6 mm at the edge and 2.5 mm at the center, providing a robust and durable design. The inner and outer radii are both 0 mm, indicating a flat edge profile. The effective focal length (EFL) of the lens is -100.82 mm, and the back focal length (BFL) is -100 mm.
