Production Engineering Measures Infrared Filter for 1KW Searchlight AN/VSS-3A.
Abstract
Combining the three pre-engineering filters made and factory tested during the last quarter with three additional filter assemblies, a group of six filter assemblies were gathered and submitted to factory level tests. All filters were found to be satisfactory in their spectral transmission characteristics, their adhesion, and resistance to storage for periods of twenty-four hours at very high relative humidity. Three filters were selected and brought to Fort Belvoir, Virginia where a satisfactory night range is available for testing of visual security when mounted in a searchlight. Two filters were tested for total periods of about eighty hours, and one of them was dissembled and examined closely for signs or evidence of sealant or filter coating deterioration. It was judged that five filters could be selected and submitted to the Government as Engineering Samples.
