[...We currently produce...] a large variety of optical components,
-singlet lenses ( Plano-convex, plano-concave, bi-convex or bi-concave),
with diammeters between 2-200 mm
-achromat doublets, computer optimised,
diamm between 6-100 mm
-prisms ( right angle, penta, Porro, Amici, etc).
Average precision 3 arc min. on angles, 2-3 arc seconds on roofs.
-mirrors (plano or spherical surfaces), coated with Al+SiO, Ag, Cr. etc
-filters made of Schott filter glasses, including tempered
heat absorbing filters All these components may be with antireflection coatings
( tipically with Magnesium Fluoride, but other coatings are available too
on special request). Average surface quality is 60/40 scratch/dig,
others on special request.
[...All dimmensional tolerances...] are +/- 0.1 mm, except centered lenses, where tipically precision is +/- 0.02 mm.
