| MAVO-
SPOT Luminance Meter |
|
The MAVO-SPOT is a very
precise light measuring instrument attached to
the MAVO-MONITOR provides precision measurements of the luminance with
an angle of 1°.
This combined equipment permits measuring the luminance at a distance
from 1 m to infinite, while taking into consideration the existing
ambient light. That measuring distance can be reduced down to 34 cm
when using close-up lenses, which are available as optional
accessories.
The MAVO-SPOT is suitable for measuring at a distance, e.g. monitors,
light contrasts at work stations, projection screens, street surfaces,
lighting of street, airfield and sports areas and lighting in museums.
It is specially suitable for checking the consistency of viewing
monitors in the medical field.
The instrument is color-corrected, i.e.
the spectral response of
the photo diode is adapted to that of the human eye V (l) according to
DIN 5032/T7 Class B.
It allows the accurate measurement of the luminance in cd/m² or fL.
