LDX-38.1-37.3-C 38.1 mm Dia. N-BK7 Image Grade Convex-Convex Lens; EFL=38.1mm Uncoated

This is the LDX-38.1-37.3-C, a high-quality convex-convex lens from CVI Laser Optics. The lens, which is part of the spherical lens category, is designed with a base shape of a circle and is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties.

The lens has a diameter of 38.1 mm and a thickness at the edge of 1.9 mm. The center thickness is 12.4 mm, providing a good balance between weight and optical performance. The effective focal length (EFL) of the lens is 38.1 mm, which is also its diameter, making it a symmetrical lens.

The lens's first radius of curvature (R1) is 37.3 mm, while the second radius of curvature (R2) is -37.3 mm. This configuration gives the lens its convex-convex shape. The inner and outer radii are 0, indicating that the lens is uniformly curved on both sides.

The lens is designed to operate at a wavelength of 546.1 nm. It is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, especially where high transmission and low reflection are not critical.

The lens is in stock and available for immediate shipping. More information about this lens, including its full specifications, can be found in the linked PDF document from CVI Laser Optics.
