The third quarter was devoted to the preparation of five Engineering Samples of Infrared Filters for the ANVSS-3A searchlight. Coated filter elements were selected which passed the spectral transmission and figure of merit tests. The filter elements were assembled and all the required tests per specification C 2a 2204010306 were performed. These filters, along with their test data, will be submitted as item 0001AA, per contract.
