14BCX1200-2-1 50.8 mm Dia. x 1200mm FL; Uncoated; Double-Convex Lens

This is a 14BCX1200-2-1 Double-Convex Lens, sourced from the reputable vendor, Standa. The lens is characterized by its circular base shape and spherical geometry, with a diameter of 50.8 mm and a thickness at the edge of 4.5 mm, transitioning to a center thickness of 5 mm. The effective focal length (EFL) of this lens is 1200 mm, making it suitable for applications that require long focal lengths.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens suitable for a wide range of applications, particularly where high image quality and low chromatic aberration are required.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost is a significant factor. However, it's important to note that uncoated lenses can be more susceptible to surface damage and may not perform as well in high-light conditions or in environments with high humidity.

The lens is designed to work with a wavelength of 546 nm, a common wavelength used in many optical systems. It's important to ensure that the lens is compatible with the specific wavelength of your system to ensure optimal performance.
