Gooch & Housego Instruments has introduced improvements to its OL 770-NVS night vision display test and measurement system, a complete solution for measurement of NVG-compatible lighting and displays. With all of the features of the original system, the new 770-NVS allows for NVIS compatible testing of Tungsten backlit devices without the need for additional filters and system calibrations.
This is achieved by utilising a concave, aberration-corrected grating spectrograph specifically designed to target the NVIS wavelength range as defined in MIL-L-86762A Appendix B / MIL-STD-3009. Not only does this simplify the measurement process, but it improves throughput and wavelength accuracy.
