39225 38.1 mm Dia. x 75 mm FL; Uncoated; Double-Convex Lens

The 39225 is a high-quality spherical lens, boasting a double-convex design and a substantial 38.1 mm diameter. This lens is sourced from the reputable vendor MKS/Newport, and its specifications make it a versatile choice for various optical applications.

The lens features a focal length of 75 mm, indicated by the "FL 75" in its name. This focal length, combined with its diameter, allows for a wide range of uses, particularly in systems where a larger aperture is required. The lens's geometry includes an edge thickness of 1.8 mm and a center thickness of 6.5 mm, contributing to its robustness and durability.

The 39225 lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes it an ideal choice for applications that require high precision and low dispersion, such as imaging systems, beam shaping, and laser applications.

The lens is uncoated, which can be advantageous in certain applications where a broadband anti-reflection coating is not necessary. However, users should be aware that uncoated lenses can have higher reflectivity, which may affect the performance in high-precision applications.
