[Products...][...We currently produce...] a large variety of optical components, such as:-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. |
