39213 25.4 mm Dia. x 33 mm FL; Uncoated; Double-Convex Lens
The 39213 is a spherical lens with a base shape of a circle, sourced from the reputable vendor MKS/Newport. This lens is a double-convex type, featuring two convex surfaces that are curved outward. The lens has a diameter of 25.4 mm and a thickness at the edge of 1.6 mm, while the center thickness measures 6.7 mm. The effective focal length (EFL) of this lens is 33 mm, making it suitable for various optical applications.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties, including high transmittance in the visible spectrum and low optical dispersion. The lens is designed to work optimally at a wavelength of 589 nm.
Notably, this lens does not come with any coating, which means it is uncoated. While uncoated lenses can be more cost-effective, they may be more susceptible to surface reflections and could benefit from anti-reflective coatings to improve their performance in certain applications.
