Plano Convex Lens (Synthetic Fused Silica) / SLSQ-25B-150P

Symmetrical biconvex lenses are most useful when dealing with finite conjugate points. This makes them ideal for 1:1 imaging applications or for use in multi-element systems.

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.

▶Please refer to here for wavelength_characteristic Data (Reference Data, EXCEL file format).
Attention

▶The biconvex spherical 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.
▶Biconvex spherical aberration is larger than that of the plano-convex lens, so focal spot may not gather at one point.
▶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.
