V- lambda radiation
The spectral range of the visible light is referred to as V-lambda radiation and corresponds to the sensitivity of the human eye. The measured value is a measure for the perceived brightness. The wavelength range extends from the end of the UV spectrum at 400 nm to the beginning of the IR range at 720 nm with a maximum at 555 nm. The determined illuminance in “LUX” can directly be converted into the irradiance “W/ m²”. Measurements in this particular range have a great importance for the workplace design and lighting projects.
V- lambda radiation sensor FLAD03VL1
V- lambda sensors are used in the field of medical and/or biological research, for weather information and forecasting systems, for climate research, for agriculture, and for the automobile industry respectively for measuring artificial lighting. The spectral sensitivity of the receiver is extremely well adapted to the sensitivity of the human eye and complies with the device class B as per DIN 5032. The measuring head FLAD 03 VL1 has a black, anodised aluminium housing. The measurement is cos corrected. The measuring head is only suitable for indoor usage.
