MAVO-SPOT 2 USB Digital Luminance Meter with 1° Measuring Angle Operating Instructions
●The high precision luminance meter for distance measurement with an acceptance angle of 1° is assigned to class B in accordance with DIN 5032-7; appendix B of DIN EN 13032-1 and CIE 69. It measures the perceived brightness of backlighted surfaces in candelas per square meter (cd/m²)) or foot-lambert (fL) in consideration of ambient light.
●The meter is equipped with an excellent adaptation to the spectral brightness sensitivity of the human eye V(λ）and is highly precise with a minimal deviation of just f1' < 3 %, which is significantly better than specified in the standard. By means of the mirror reflex optics; the measuring subject may be targeted precisely in a 15° field of view and a sharply marked 1° measuring circle in the center of the viewfinder. Focus can be set for distances ranging from 1 meter to infinity. Shorter distances as of 34 cm are made possible by means of optional close-up lenses. Alternatively contact measurement can also be performed with an optional, top quality probe. The velvety coating on the adapter disc prevents scratching of self-luminous and back-lighted surfaces.
