The pride of our company has always been the creation of flat optics. We have 2 horizontal interferometers, 2 vertical interferometers and 1 pianometer, which allow us to verify the flatness of our optics up to λ / 20 and the parallelism up to 5 "(depending on the thickness and diameter). The measurements supplied by us and the tolerances are always referred to the wavelength of the He-Ne laser (632.8 nm).

We are able to work with all the optical glasses in the catalog, as well as with silicon, germanium, ZnS, ZnSe, fused silica and crystalline materials (MgF2, Caf2, barium fluoride etc.). Our production processes allow us to obtain surface roughness up to Rq 0.4 nm on optical glasses, Rq 0.8 nm on crystals and Rq 0.9 on paste filters. Traditionally, we work with optical surfaces with a laser finish for CO2 laser applications (biomedical and in particular dermatological). In addition to geometric references, we also construct gratings and polarizers, optical prisms, filters and optical dispersions.

LAMINae

Simple geometry components that often require high quality in terms of dimensional constructional specifications, parallelism and planarity even on very thin elements.

We create laminae with custom geometries for any type of housing, which can also be supplied on customer specific frames.

windows

Often used as an opto-mechanical interface, they are used in the most diverse sectors. Thanks to our high efficiency coatings (qualified according to military standards) our optical windows are particularly appreciated even for applications that require good mechanical resistance in hostile environments (such as in the naval sector).

GEOMETRIC REFERENCES

We construct plane parallel plates or controlled angle for interferometric applications. The most prestigious metrological laboratories regularly collaborate with us for the characterization and verification of our products. In addition to plane references, we have made silicon spheres destined to become mass reference samples.
