3.1 V (λ) Matching error V (λ) matchingerror In theory, the relative spectral response of the illuminance meter is fully consistent with the visual function V (λ), whereas the actual optical radiation detector Spectral response degrees are far from the difference, must be corrected by correcting filter group to be matched. Matching the illuminance The deviation of the relative spectral response of the detector from the visual function is the V (λ) matching error. 3.2 Cosine characteristic error cosinecharacteristicerror The cosine law shows that when the beam is illuminated at an angle to the illuminance surface of the illuminometer detector, the illuminance reading should The product of the reading when the beam is incident at the same time as the cosine of the incident angle. The actual illuminance meter can not exactly conform to the cosine method Then its deviation from the cosine law is the cosine characteristic error. 3.3 Fatigue characteristic error Fatigue characteristics of the photometric light detector photosensitive surface to receive a strong light radiation, the detector response will gradually decline phenomenon. The resulting error is called the fatigue characteristic error.

4 Overview

The illuminometer is a measuring instrument that measures the illuminance, which is corrected by the optical head [including cosine corrector, V (λ) Device, photoelectric receiver] and the display (digital or pointer type) composed of two parts. When the photoelectric receiver is received through Cosine modifier and V (λ) filter, the resulting photoelectric signal is signaled on the display Showing the corresponding illuminance value. ...
