KBX034 12.7 mm Dia. x 50.2 mm FL; Uncoated; Double-Convex Lens
The KBX034 is a high-quality spherical lens, specifically designed for use in a wide range of optical applications. Manufactured by MKS/Newport, this lens boasts a 12.7 mm diameter and a focal length of 50.2 mm, making it a versatile choice for many setups.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible spectrum. This material is known for its low dispersion, making it an ideal choice for applications where chromatic aberration is a concern.
The KBX034 features a double-convex design, with radii of curvature of 51.234 mm and -51.234 mm for the first and second surfaces, respectively. This design allows for a high degree of focusing power, making it suitable for use in imaging systems, beam shaping, and other applications where a tight focus is required.
The lens has a thickness of 3 mm at the edge and 3.79 mm at the center, providing structural rigidity while minimizing unnecessary weight. The inner and outer radii are both 0, indicating a uniform curvature across the lens surface.
Notably, this lens is uncoated. While coatings can enhance the performance of a lens by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be a cost-effective choice for applications where such enhancements are not necessary.
