Biconvex Lens 15mm Diameter 25.7mm Focal Length Uncoated

SLB-15B-25P

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.
◦There are two types of biconvex 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.

Leitfaden
  • 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.
  • WEB Reference Catalog Code/W3075
Anmerkung -
Achtung
  • The biconvex spherical lens has 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” 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.
