32-894 40.0mm Dia. x 80.0mm FL; Uncoated; Plano-Convex N-K5 Lens
The 32-894 is a Plano-Convex Spherical Lens with a diameter of 40.0mm and a focal length of 80.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical elements. The lens is made from N-K5 Schott glass, a material with exceptional optical properties, making it suitable for a wide range of applications.
The lens geometry includes a thickness of 2.91mm at the edge and 8.0mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The back focal length (BFL) is 74.78mm, and the effective focal length (EFL) is 80.0mm. The radius of curvature (R1) is 41.84mm.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of a lens in certain applications, an uncoated lens can be advantageous in others, such as when minimal reflection is required.
The lens is designed to work with a wavelength of 587.6nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is used with.
