111-0404E 38.1 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens
The 111-0404E is a high-quality double-convex lens, sourced from EKSMA Optics, with a diameter of 38.1 mm and a focal length of 50 mm. This lens is made of BK7 Schott, a popular borosilicate crown glass known for its excellent optical properties, including a low refractive index and low dispersion.
The lens features a base shape of a circle, with an edge thickness of 3 mm and a center thickness of 10.5 mm. The inner and outer radii are both 0, indicating a symmetrical design. The effective focal length (EFL) is 50 mm, which is the distance from the lens's principal point to the focal point.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens by reducing glare, increasing transmission, or providing other benefits, an uncoated lens can be a suitable choice for applications where such enhancements are not necessary.
