16 Nov 2009 The JAZ Light Meter is a pre-configured, pre-calibrated, portable spectroradiometer that tells the truth, the whole truth and nothing but the truth when it comes to reporting the illuminance from LEDs The JAZ Light Meter is based upon a CCD spectrometer, but unlike standard instruments, the JAZ is fully self-contained and does not need to be tethered to a PC. With on-board photometric processing, plus battery pack, data storage and an integrated OLED display, the JAZ Light Meter is the first truly portable spectroradiometer for measuring the spectral irradiance and illuminance of light source.
The JAZ Light Meter functions as an illuminance colorimeter but unlike tristimulus filter-based meters, the JAZ reports the correct illuminance (in lux) regardless of the type of light source under test. It has become common knowledge that inexpensive lux meters can give very misleading readings with narrow spectrum light sources such as LEDs. |
