111-0128E 12.7 mm Dia. x 125 mm FL; Uncoated; Double-Convex Lens

The 111-0128E is a high-quality double-convex lens, sourced from the reputable optical components manufacturer, EKSMA Optics. This lens boasts a 12.7 mm diameter and a focal length of 125 mm, making it suitable for a wide range of optical applications.

The lens is fabricated from BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high chemical resistance. The BK7 Schott designation indicates that the glass meets the stringent quality standards set by Schott, a leading glass manufacturer.

The lens geometry is characterized by its spherical shape, with both surfaces curved outwards. The first surface has a radius of curvature of 129.3 mm, while the second surface has a radius of -129.3 mm. This double-convex design allows for efficient light concentration and minimal spherical aberration.

The lens has a thickness of 1.7 mm at the edge and 2 mm at the center. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and uncoated lenses are often preferred for their cost-effectiveness and simplicity.
