Night Sky Illuminance Monitor

Hoffman’s ANV-410

Night Sky Illuminance Monitor

OVERVIEW

Hoffman Engineering has developed a series of portable, battery operated, silicon Photometers/Radiometers with precision ranges and sensitivity to measure night sky illuminance in both the visible and night vision spectrums identify as ANV-410B and TSP-410, these instruments are designed for use in the field to measure ambient illuminance and assist in NVD mission planning.

The TSP-410 is photopically filtered and calibrated to measure and display in Lux. The ANV-410A is filtered and calibrated to match the Class ‘A’ response identified in MIL-L-85762A. The ANV-410B is filtered and calibrated to match the Class ‘B; response identified in MIL-L-85762A. The ANV-410x series radiometers calibrated to and display units in what can be characterized as NVIS Lux. All three instruments operate on four (4) decade ranges of amplification with selection controlled by the front panel range switch. A cover is provided for the detector, permitting the user to zero/null the instrument prior to use.
