KBC022 12.7 mm Dia. x -50 mm FL; Uncoated; Double-Concave Lens
The KBC022 is a high-quality spherical lens, specifically designed for use in optical systems that require a concave-concave lens shape. This lens is sourced from the reputable vendor, MKS/Newport, and is available directly from their website.
The lens boasts a 12.7 mm diameter, making it suitable for a wide range of applications. It features a double-concave design, with a center thickness of 2.5 mm and an edge thickness of 3.13 mm. This design results in a back focal length of -50.81 mm, providing a negative focal length of -50 mm.
The KBC022 is crafted from N-BK7 Schott glass, a material well-known for its excellent optical properties. This includes a high Abbe number, low auto-fluorescence, and excellent transmission in the visible and near-infrared regions. The lens is uncoated, providing a cost-effective solution for applications where coating is not required or desired.
This lens is designed to operate at a wavelength of 589 nm, making it suitable for use in a variety of optical systems. The lens's geometry is defined by its inner and outer radii, both of which are 0 mm in this case, indicating a flat surface.
