◦It has the same specification of Plano Convex Lens (SLB-P) except the surface quality and is ideal for experiments and applications where high-precision is not required.
◦There are two types of lens offer, a Plano convex lens with low spherical aberration and a biconvex lens that is used to shorten the focal length.
◦In addition to uncoated products, there are three types of anti-reflection coating for visible, near-infrared, and infrared.

Guide ▶Please refer to here for wavelength_characteristic Data (Reference Data, EXCEL file format).
Attention ▶Plano convex lens have a 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” of Plano convex lenses (SLB-P) for the focal lengths of each wavelength.
WEB Reference Catalog Code/W3041-1
▶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.
