The 39223 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 a diameter of 38.1 mm and a center thickness of 9.1 mm. The edge thickness of this lens is 2 mm, providing a robust structure. The effective focal length (EFL) of this lens is 50 mm, making it suitable for a variety of optical applications.
The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties. The lens is designed to work optimally with a wavelength of 589 nm. The radii of curvature for this lens are r1: 49.434962 and r2: -49.434962, indicating its double-convex nature. The inner and outer radii are both zero, suggesting a symmetrical design.
Notably, this lens does not come with any coating, making it a bare-glass lens. This could be beneficial in applications where coating might interfere with the desired optical properties. However, users should be aware of the potential for increased reflection and reduced transmission without a coating.
