DCX1803 25.4 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens

The DCX1803 is a Double-Convex Spherical Lens, a high-quality optical component manufactured by Union Optic. This lens boasts a diameter of 25.4 mm and a focal length of 50 mm, making it suitable for a wide range of applications.

The lens is uncoated, offering a bare, unaltered glass surface. This can be advantageous in certain applications where coating might interfere with the desired optical properties. However, it's important to note that uncoated lenses may be more susceptible to surface damage and may not perform as well in high-light conditions due to internal reflections.

The geometry of the lens is characterized by its edge thickness of 2 mm and center thickness of 5.7 mm. The lens's effective focal length (EFL) is 50 mm, and the back focal length (BFL) is 48 mm. The first and second radii of curvature (R1 and R2) are 45.1 mm and -45.1 mm, respectively.

The lens is made from UVFS Mal-1965, a material with specific optical properties that make it suitable for various applications. The material's refractive index and Abbe number can significantly influence the lens's performance, particularly in terms of chromatic aberration and dispersion.

This lens is designed to work with light of wavelength 546.1 nm. The choice of this wavelength can be crucial, depending on the application, as it can affect the lens's focusing capabilities and overall performance.
