PRECISION OPTICS

Grinding, polishing and optical centering at their best

A huge part of Tecnottica’s production is now dedicated to the manufacturing of plano and spherical optical components who require very tighten optical and geometrical tolerences; these elements are usually inserted in machine vision systems, imaging systems and in setups for laser applications.

The precision optics department, built into a separated area of our plant in Calco, has been studied in a way that can operate independently from the rest of the production. Through this philosophy Tecnottica protects and guarantees the respect of tolerances and lead times of all its product lines by differentiating his own offer directly starting from the production area itself.

Thanks to constant investments in state-of-the-art machinery, Tecnottica is able to generate, polish and center optical surfaces (with diameters ranging from 2.7 to 310 mm (0,106in to 12,205in) and with the highest standards currently allowed by the technology of the sector we can obtain flatness values up to lambda / 20, while Optical cementing and combined centering of achromatic doublets are guaranteed with centerings below 30”.
