Plano Concave Lens 2mm Diameter -4mm Focal Length
SLM-02-04N
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.
◦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.
