32-874 25mm Dia. x 125mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as 32-874, boasts a diameter of 25mm and a focal length of 125mm, making it a versatile choice for a wide range of optical applications.

The lens is crafted from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material ensures the lens delivers superior performance and maintains its integrity even under demanding conditions.

The lens surfaces are coated with EDM MgF2 std curve, a proprietary coating developed by Edmund Optics. This coating enhances the lens's performance by reducing reflection and increasing transmission across the visible spectrum (400-700nm). The coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and minimal loss.

The geometry of the lens is meticulously designed, with an inner radius of 0mm and an outer radius of 0mm. The lens has a thickness of 2.28mm at the edge and 3.5mm at the center, providing a robust structure that can withstand typical use. The effective focal length (EFL) is 125mm, and the back focal length (BFL) is 123.84mm, offering precise focus control and compatibility with various optical systems.
