The high-precision luminance meter Mavo Spot2 USB for distance measurement with 1 ° measuring angle is classified in class B according to DIN 5032-7, DIN EN 13032-1 Appendix B and CIE 69. It measures the brightness effect of a luminous surface in candelas per square meter (cd / m²) or footLampert (fL) taking into account the ambient light.
The MAVO-SPOT2 USB has an excellent adaptation to the spectral brightness perception of the human eye V (λ) and, with the slight deviation of f1 '<3%, is significantly better than the requirement from the norm Field of view and a sharply marked 1 ° measuring circle in the center. The distance setting ranges from 1 m to ∞. Shorter distances from 34 cm are achieved using optional close-up lenses.
Alternatively, an attachment measurement is possible using an optional high-quality measuring head. The velvety coating of the adapter disc prevents scratches on the self-illuminating or illuminated surface.
With the convenient one-hand operation, measuring functions are selected and measurements started. Pressing a button activates the display in the viewfinder and its backlighting. The comparison and ratio measurements are particularly advantageous, in this case the deviation of a measured value B from a reference value A is assessed and displayed. The ratio A / B is used to measure contrast at the workplace. The percentage deviation% A enables the assessment of the uniformity of screens or the illumination of projection screens and the difference AB is used to control deviations in production.
