Plano Convex Lens 3mm Diameter 2.5mm Focal Length

SLM-03-2.5P

Micro lenses are spherical plano convex/biconvex lenses with diameters smaller than 4mm. These small lenses are designed for use in equipment and instruments that demand lighter and smaller footprint optics.
◦Spherical plano convex lenses are useful when parallel beams are converged or lights from sources are converted to parallel beams, i.e., at infinite conjugate ratios.
◦Spherical biconvex lenses are useful when lights from sources are converged or images are relayed to other optical systems, i.e., at unit conjugate ratios.
◦Since these lenses are designed at the wavelength 587.6nm (yellow helium line [d]), the focal lengths of them vary at other wavelengths.

Guide
  • In addition to our standard products listed on-line and in the catalog, custom products are available. Please contact our Sales Division for assistance with your request.
Remark -
Attention
  • The micro lenses have spherical 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.
  • The plano convex lenses are designed for parallel light to be incident to the convex surface. Using the lens in reverse may increase the spherical aberration and the focused spot may enlarge and the image will appear out of focus.
  • 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.
