photometric

The 480 Analyzer produces 400 photometric results per hour and 240 ISE tests per hour with an overall throughput of 560 tests per hour.

Of these, about 7,000 were visual observations (naked-eye, binoculars, or telescope); the others are photometric measurements taken at various wavelengths with digital detectors (CCDs, DSLRs, photoelectric photometers).

Photometric results from field measurements, which for the Woodridge installation appear to also light a roadway, are noted to meet IES recommendations for pedestrian walkways distant to roads and seem to show only illuminance reading along the pathways.

Tailor Made Systems Ltd/TMS Photometrics is the world's leading supplier of photometric measurement equipment, and associated services for airfield ground lighting (AGL) systems.

With nothin as exact as modern photometric measurements, they had to interpret such terms as obtusior, duller or blurred, and rubicundior, ruddier.

Unfortunately, while we have great astrometric catalogs, we don't have an equivalent high-quality photometric catalog covering the entire sky.

The study--conducted in conjunction with the New York State Energy Research and Development Authority (NYSERDA) and Sullivan Renaissance--analyzed the luminaires based on four main criteria: photometric performance, system performance, energy savings and public reception.

For instance, MALMS is a prime example of the mobile photometric measurement technology now recommended by the ICAO, UK CAA, FAA and other national regulators as the only effective means of determining the true performance of lighting services.
