Interlaboratory Study (ILS) of the Standard Test Method for Measuring the Night Vision Goggle-Weighted Transmissivity of Transparent Parts

There are several ASTM Standards that address light transmissivity through transparencies (ASTM Standards F 1316-90D and 1003-61) in the visible spectrum (400 through 700 nm). However, night vision goggles (NVGs) are now being used in aircraft and other applications (e.g., marine navigation, surveillance, personnel carriers) with increasing frequency. These devices amplify both visible and near-infrared (NIR) spectral energy. A transparency may have excellent visible transmissive characteristics but could have poor NIR transmissivity. Overall visual performance (acuity) can be degraded if the observer uses the NVGs while looking through a transparency that has attenuated transmissivity in the NIR region (Pinkus and Task, 1997, see Appendix A). ASTM P94-02, Standard Test Method for Measuring Night Vision Goggle-Weighted Transmissivity of Transparent Materials (see draft in Appendix B) addresses this issue.Air Force Research Lab Wright-Patterson AFB OH Human Effectiveness Directorate is the author of 'Interlaboratory Study (ILS) of the Standard Test Method for Measuring the Night Vision Goggle-Weighted Transmissivity of Transparent Parts', published 1998 under ISBN 9781423562764 and ISBN 1423562763.
