112-0223E 25.4 mm Dia. x -125 mm FL; Uncoated; Plano-Concave Lens

The 112-0223E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -125 mm, sourced from EKSMA Optics. This lens is a spherical type, designed with a base shape of a circle, and is uncoated.

The lens's geometry is meticulously crafted, with an edge thickness of 4.2 mm and a center thickness of 3 mm. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens. The concave shape of the lens is designed to diverge light rays, making it ideal for use in applications such as beam expanders, collimators, and other optical systems where light needs to be spread out.

The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties and high durability. It is designed to operate at a wavelength of 546 nm, making it suitable for use in a wide range of applications, including spectroscopy, metrology, and laser systems.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the user wants to minimize reflections or where cost is a significant factor. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust and moisture, and may require more frequent cleaning.
