111-0410E 38.1 mm Dia. x 100 mm FL; Uncoated; Double-Convex Lens
This is a 111-0410E Double-Convex Lens, a high-quality optical component sourced from EKSMA Optics. The lens has a base shape of a circle and is designed for use in a wide range of optical systems due to its versatile specifications.
The lens has a diameter of 38.1 mm, making it suitable for applications that require a larger aperture. The center thickness of the lens is 6 mm, while the edge thickness is 2.4 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of the lens is 100 mm, which is a common choice for many optical applications.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes the lens suitable for use in systems operating at a wavelength of 546 nm. The lens has a refractive index of 1.5168 at this wavelength.
The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can suffer from unwanted reflections, which can reduce the overall system efficiency.
