BTS256-E

Traditional lux meters are increasingly being replaced by spectral light meters such as the MSC15. However, the lighting industry also needs high accuracy spectral light meters that can handle more complex measurements. These include measurement of pulse width modulated light and the ability to measure both internal and external illumination, determination of thermal transient behavior of lamps, and so on. The primary criterion that such meters must always meet is the quality of their photometric features. Additional electronic features may improve usability and display quality, but they cannot compensate for substandard measurement results.


BTS256-E – compact, hand-held meter for complex measurements

With the BTS256-E, Gigahertz-Optik GmbH offers a light meter that is perfectly suited for complex measurements in the lighting industry. Its technical concept guarantees high-quality measurement of illuminance, spectrum, color, and color rendering index (video). The heart of this compact device is its BiTec sensor which combines two different sensor technologies, i.e. a Si photodiode with a V-lambda filter and a spectroradiometer unit that is based on a CMOS diode array.

The Si photodiode offers extraordinary properties in terms of dynamic range, linearity, and speed of measurements. Combining the two allows mutual correction (BTS technology) in order to ensure even higher accuracy. Another unique feature is its ability to perform time-synchronized measurements of pulse-width modulated light and hence guarantee correct illuminance measurements in PWM lighting systems.

The spectrometer ensures high accuracy in luminous spectral measurements and has a 10 nm optical bandwidth in the spectral range between 380 nm and 750 nm. An optical bandwidth correction function according to CIE 214 is incorporated, further improving the quality of values (e.g. peak wavelength) that are calculated based on the spectral measurement data. Given its compact size, the unit exhibits outstanding scattered light performance which provides extraordinary precision even in complex measurements. Another key feature of this compact light meter is the remote-controlled shutter for automatic dark signal correction.

A significant consideration for precise illuminance measurements of lighting systems is the field of view of the measurement optics. Correct illuminance measurements are only possible with a precise cosine field of view function for the different angles of incidence.

The device is extremely easy to use thanks to the intuitive menu and the supplied software with which it can be controlled remotely. The device housing is watertight for outdoor light measurements.


 Calibration of the BTS256-E

One essential quality feature of photometric devices is their precise and traceable calibration. The BTS256-E is calibrated by Gigahertz-Optik’s calibration laboratory that is accredited by DAkkS (D-K-15047-01-00) for the spectral responsivity and spectral irradiance according to ISO/IEC 17025. The calibration also included the corresponding accessory components. Every device is delivered with its respective calibration certificate.
