Plano Convex Lens 40mm Diameter 50mm Focal Length Uncoated

Ref:207001
These are simple lenses having a flat surface on one side and a spherical surface on the other. They are also very close to the form which minimizes spherical aberration for infinite conjugate applications. Our glass lenses are made from the highest grade of optical glass. We have a vast range of different diameters and focal lengths. The lenses listed here are standards. Please call if you do not see the lens you need. We have both larger and smaller lenses and many other diameters to choose from. However, we do try to keep these standards available for quick delivery.

There are three types of plano convex lenses available; BK7 for use in visible range to infrared wavelength range.

BK7 lenses are also available with three types of anti-reflection coatings, visible wavelength range, in the near-infrared range and in the infrared range.

Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.
