Due to its innovative BiTec-Light sensor, the new BTS256-E light meter is tailored to the particularities of LED.
The BiTec-Light sensor allows for compact measurement devices providing high quality measured values of illuminance, color rendering including CRI R15, luminous color and light spectrum, also applicable for pulse width modulated (PWM) light. In addition to the stand-alone operation, the device can be operated in connection to a computer. The S-BTS256 software supports the various fields of application of the BTS256-E light meter due to its modular desktop appearance.
The trend towards LED use in general lighting is unprecedented. This is due to the high energy efficiency, significantly longer lifetime and the diverse design options compared to incandescent bulbs, fluorescent lamps and energy-saving bulbs.
In the same way incandescent bulbs have been replaced by the new technology, traditional photometers and light meters have also been superseded by advancements in measurement technology. The new measurement techniques must be tailored to match LED lights specifications and besides being used to measure the illuminance, one should also be able to use them for color rendering, luminous color and luminous spectrum measurements.
The BTS256-E light meter is built with the cutting-edge Bi-Technology Light Sensor BTS256 from Gigahertz-Optik. One of its distinguishing features is that it includes a photodiode and a photodiode array. The combination of these two sensor technologies enables the configuration of compact light meters with specifications for high quality light measurement applications.
The BTS256 light sensor’s diode array supports a 10nm spectral resolution. In conjunction with the 256 pixel, precise measurements of the luminous spectrum are assured even with line spectra. An automatic shutter in front of the diode array enables pixel-dark signal compensation and thus fully utilizing the dynamic range of the diode array detector.
