112-0243E 25.4 mm Dia. x -400 mm FL; Uncoated; Plano-Concave Lens

The 112-0243E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -400 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or enhance its optical properties.

The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a thickness of 4 mm at the edge and 3.6 mm at the center. The inner and outer radii are both 0, indicating a plano surface on one side and a concave surface on the other. The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold.

This lens is suitable for applications that require negative lens power. It can be used in various optical systems, including cameras, telescopes, and microscopes. However, due to its uncoated nature, it may not perform optimally in high-intensity light environments or in applications where surface protection is crucial.
