The range of HVIR expands with a new window in order to adapt to the hardest conditions. H.VIR 85 TYPE 21C and H.VIR 105 TYPE 22C fitted with Germanium crystal with DLC (HARD CARBONE) coating on external face and AR (ANTI-REFLECTING) coating on internal face offer a very good transmission and a higher resistance to environment. It is an ideal product for the most severe conditions (possibility of using wiper – see standard) of maritime, metallurgical industries. Derived from the same range which makes its success and its lifetime, types 21C and 22C assemble and install respectively as type 21 and 22.
