Plano Convex Lens (BK7) / SLB-100-300PIR1

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.

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.

Attention

▶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 for the focal lengths of each wavelength.
▶Plano-convex lenses have a specified direction of incident light. Make sure that the collimated light is incident from the convex side. If it is reversed, spherical aberration will increase, and the focused spots may not converge sufficiently or the image may appear blurred.
▶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.
