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.

Guide

▶Lenses are available in a large selection and in custom sizes and focal lengths.
▶In addition to our standard coating we offer custom anti-reflective coating at specific wavelengths.
▶Achromatic lenses (DLB) which are chromatic aberration correction are also available.
W3075
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶Plano convex lenses have a positive focal length and can be used in focusing and collimating applications.
▶The plano convex lens has chromatic aberration, and the focal length will vary depending on the wavelength. Please check the “wavelength characteristic of the focal length data” on “Technical Data” for the focal lengths of each wavelength.
▶Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
