Light measurement goniometer GB-GD-360-RB40-2-BTS2048-VL

Measurement of the luminous intensity distribution Luminous intensity distribution is used to specify the directional radiation characteristics of lamps. It is determined through numerous separate measurements of the luminous intensity. Every measurement detects the light emitted into the half space around the lamp under a different viewing angle. The measurement data are represented in polar plots and 3D graphs and output in standard formats e.g., IES, EULUMDAT, Excel, etc. This data can also be used to calculate the luminous flux. 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 diffusor window with cosine corrected field of view for the measurement of spectral irradiance and spectral illuminance. This also makes it possible to combine the BTS2048-VL with goniometers for the measurement of luminous intensity distributions. Its impressively wide dynamic range makes it ideal for the measurement of spot lamps that have a distinctive edge profile. 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.
