The L-MBX004 is a 4.5 mm diameter double-convex lens, uncoated and sourced from Ross Optical. This lens is a spherical type, specifically a convex-convex lens with a circular base shape. The lens's geometry is defined by its diameter, thickness edge, and center thickness, which are 4.5 mm, 1.8 mm, and 2.6 mm respectively. The effective focal length (EFL) is 4.5 mm, and the radii of curvature for the first and second surfaces are 4.16 mm and -4.16 mm respectively.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties. The wavelength for this lens is 587.6 nm. The lens does not come with any coating, as indicated in the item data.
This lens is ideal for applications that require a compact, high-performance optical element. Its double-convex design provides a wide field of view and low distortion, making it suitable for various imaging and illumination applications.
