KBX184AR.33 50.8 mm Dia. x 1000 mm FL; Double-Convex Lens Laser V-Coat 1064nm

This KBX184AR.33 double-convex lens, sourced from MKS/Newport, is a high-quality optical component designed for use in a variety of applications. With a diameter of 50.8 mm and a focal length of 1000 mm, it offers a substantial effective focal length (EFL) of 1000 mm, making it suitable for systems requiring significant optical power.

The lens is crafted from n-BK7 Schott glass, a popular material known for its excellent optical properties and versatility. This spherical lens features a base shape of a circle, with an edge thickness of 3 mm and a center thickness of 3.625 mm. The inner and outer radii are both 0, indicating a symmetrical design.

The KBX184AR.33 lens boasts an anti-reflective (AR) coating on both the front and back surfaces. This AR-33 coating is specifically designed for use with a wavelength of 589 nm, enhancing the lens's performance in systems operating at this frequency.

Please note that the lens's back focal length (BFL) is 998.8 mm, a slight reduction from the EFL due to the curvature of the lens. This information is crucial when integrating the lens into an optical system, as it affects the overall system's alignment and performance.

The lens's geometry, including its diameter, thickness, and radii, is designed to provide optimal performance while minimizing aberrations. The double-convex design, in particular, helps to reduce spherical aberration, a common issue in optical systems.
