NTM36Housing 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.

The AISI 316L stainless steel construction allows the installation in environments with highly corrosive external agents, such as marine, industrial or chemical environments.


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
