The BTS2048-VL light meter

The high-quality BTS2048-VL CCD based spectroradiometer is internationally recognized as a high-end product. It is one of the most compact spectroradiometers on the market which enables direct system integration in many applications without the need for expensive, and potentially measurement degrading, light guides. Among its characteristic features is its diffuser window with cosine corrected field of view for the measurement of spectral irradiance and spectral illuminance. This also permits direct mounting onto integrating spheres (e.g. the ISD-100HF) for measurement of luminous flux. More detailed information about the BTS2048-VL can be found in the respective data sheets. The unit is also available in the BTS2048-VL-TEC thermoelectric cooled version.


Enhancement of the BTS2048-VL with the ISD-100HF-V05 and ISD-100HF-V06 integrating spheres

The 100cm diameter integrating sphere ISD-100HF-V05 can be combined with the BTS2048-VL to measure the luminous flux, spectrum, color, and color rendering index of single LEDs, LED arrays, and LED lamps. Light sources with 2pi and 4pi radiation characteristics can be measured in accordance with CIE 127 requirements.  One hemisphere can be opened to facilitate placement of test lamps in the sphere centre using the height-adjustable sample holder.  Four-terminal electrical connection in incorporated.The ISD-100HF-V06 variant has an extra measurement port for 2pi lamps with diameters of up to 254 mm (10 inches). This remains closed when not in use. .. A baffle is integrated in front of the measurement device to shadow an area within 300 mm from the center of the sphere. The auxiliary lamp helps compensate for self-absorption effects during measurements. The combination of the BTS2048-VL and ISD-100HF meets the requirements of the CIE 127, CIE S025, and LM-79-08 for the measurement of luminous flux of directional (2pi) and non-directional (4pi) LED lamps. These include the spectral resolution, dynamic range, and stability of the spectroradiometer as well as the ideal sphere coating, auxiliary lamp, coupling of measurement devices using the diffusor window, a baffle and the optionally available temperature sensor.


Calibration

One essential quality feature of photometric devices is their precise and traceable calibration. The ISD-100HF with the BTS2048-VL has been calibrated at Gigahertz-Optik’s DAkkS-accredited (D-K-15047-01-00) calibration laboratory for the spectral responsivity and spectral irradiance according to ISO/IEC 17025. Calibration of the luminous flux is performed by placing a BN-LHSF-104 lamp at the center of the sphere. The extra measurement port requires calibration using a BN-LHSF-2P-20 calibration lamp that has 2pi radiation characteristics. Every device  comes with its respective calibration certificate
