COMAR Optics

Add to watch list

Negative lenses form a reduced virtual image of a real object (as in door viewers). However, if inserted in a system such as a microscope upstream from an image plane, the image will be magnified and projected further. Such a lens is known in microscopy as a tube-length correction lens and in astronomy as a Barlow lens. We ...

Plano-Concave Spherical Lens

Atoptical Co., Ltd

Add to watch list

Plano-Concave Lenses are the best choice where object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical.Plano-Concave lenses bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length.The spherical aberration of the ...
