NTMHousing for thermal cameras in hostile environments



This housing for thermal camera provides the vision also in complete darkness, fog, rain, smoke or for long-range distances.

The germanium window has non-scratch treated, Hard Carbon Coating (DLC) on the outside and antireflection inside; the spectral range is from 7.5μm to 14μm.


Made of AISI 316L stainless steel to withstand the most hostile outdoor environments

Cylindrical body enclosed by two 9mm(0.4in)-thick circular flanges

2 PG13.5 cable glands in nickel-plated brass for external connections
