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 diffusor window which permits direct mounting onto integrating spheres (e.g. the ISD-15) 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. Use of the BTS2048-VL for front-end and back-end LED binning The BTS2048-VL is ideally suited for use in industrial LED binning. In particular, it can be used to perform time-synchronized, pulsed measurements of LEDs as stipulated by CIE S025 or DIN 5032-9. This is necessary when one wants to account for thermal effects in measurements. The instantaneous, electronic zero setting of all pixels (electronic shutter) of the CCD sensor in conjunction with its trigger interface, results in perfect synchronization between the BTS2048-VL’s measurement and the LED current supply. The device also has an exceptionally wide dynamic range with a minimum integration time of just 2 µs. This, is 1000 times shorter than conventional devices (typically milliseconds), hereby makes it possible to achieve an OD3 factor. Additionally, the internal OD1 and OD2 filters increase the dynamic range up to 9 orders of magnitude and the fast Ethernet interface provides rapid data transfer.
