32-878 25mm Dia. x 175mm 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 32-878, boasts a 25mm diameter and a focal length of 175mm, making it suitable for a wide range of optical applications.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry is characterized by its double-convex shape, with radii of curvature of 180.4mm and -180.4mm for the first and second surfaces, respectively. The lens has an edge thickness of 2.33mm and a center thickness of 3.2mm, contributing to its robustness and durability.

The lens features a standard MgF2 coating on both the front and back surfaces. This coating, known for its excellent transmission properties in the 400-700nm spectral range, reduces reflection and increases the lens's overall efficiency. The coating is applied using Edmund Optics' standard curve, ensuring consistent performance and quality.
