112-0505E 50.8 mm Dia. x -100 mm FL; Uncoated; Plano-Concave Lens
The 112-0505E is a Plano-Concave Spherical Lens, sourced from EKSMA Optics, a leading vendor in the optical components industry. This lens boasts a diameter of 50.8 mm and a focal length of -100 mm, making it ideal for applications that require negative focal lengths.
The lens is made from the material n-bk7 schott, a popular choice in the industry due to its excellent optical properties. The base shape is circular, and the lens is uncoated, offering a clear, unaltered optical path. The edge thickness of the lens is 10 mm, while the center thickness is 3.5 mm, providing a robust and durable structure.
The geometry of the lens is unique, with an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The effective focal length (EFL) is -100 mm, which is the distance from the lens's secondary focal point to the lens when the object is at infinity.
This lens is designed to work at a wavelength of 546 nm, making it suitable for a wide range of applications. The lack of coating on the lens allows for unaltered light transmission, making it ideal for applications where minimal light interference is required.
