Luminance measuring camera for a spatially resolved analysis of luminance distributions
Energy Efficiency and Indoor Climate
| Measurement | Spatial luminance distribution of indoor and outdoor environments, photometric image analysis |
| Standard | DIN 5032 |
| Measurement object | Luminous and illuminated surfaces covering a wide range of visual environments from VDT to daylight situations |
Technical data
| Camera | 1.4 megapixel CCD detector, photopic spectral correction |
| Typical luminance range | 0.015 to 50,000 cd/m² (with filter up to 5 × 109 cd/m²) |
| Lenses | Wide angle, fish eye |
Special features
| Filter | Neutral density filter with transmission of 1 and 0.01 % to raise the maximum measurable luminance |
| Analysis | Using the software luminance values can be measured over a series of measuring points or as complete surfaces. |
