Re: [ATM] Too Small Optics

Richard S asks:

>Dumb Question:  how do they test and figure microscope lenses?

They dont..they just control the spherical surfaces
to close tolerances..small steeply curved surfaces
will naturally assume a spherical shape when lapped & polished.
You can test the finished objective by viewing a resolution
pattern with it..these patterns can have <1 micron spacing.

They also make all-reflective microscope objectives, for
IR and UV applications..these are essentially miniature Cassegrain
objectives designed for use up close.

Another *precise* small lens application is the molds used to
make contact lenses..you need hundreds of these and they're not
cheap.
