NVG-102 & 103 NVIS Inspection Scope

The NVG-102B is designed as a simple and field-effective method of inspecting NVG Compatible crew stations for continued compliance.  The specially designed Long-Pass filter (-006) will admit offensive wavelength energy to the image tube for viewing by the operator.  The offending lighted product or display can then be repaired or removed from the crew station to assure NVG activity without impaired visual acuity.

The NVG-102B is unlike "off-the-shelf" moncular or other image intensifier products.  Hoffman's NVIS inspection scopes are precision-calibrated, certified reference tools designed for the purpose of evaluating cockpit lightling compatibility and external aircraft covert lighting.  These inspection scopes feature up to four calibrated gain settings that enable them to evaluate a broad range of lighted devices.

 

Features

All Hoffman Engineering Inspection Scopes feature function specific filters and lenses that are tailored to the system's image intensifier tube and application.  This provides NIST-traceble luminance gains and military-specified or application specific spectral responses.

Benefits

The Battery Circuit Continuity Tester requires no annual calibration and complies with the testing requirements for 90 and 180 day checks.
