Datacolor 800, 850, 500, and 550 Series User’s Guide 8
Below are aperture plate specifications:
Aperture
Identification
Sample Area
Measured
Sample Area
Illuminated
LAV 26mm 30mm
MAV 16mm 20mm
SAV 5mm 9mm
USAV 2.5mm 6.5mm
XUSAV 2.5mm 3.0mm
NOTE
The area illuminated is always 4mm greater than the diameter measured to reduce
translucency errors. The exception to this is the XUSAV plate.
Tips for Aperture Selection
Always use the largest possible aperture size.
The Large Area View (LAV) plate is recommended for averaging samples with
irregular surfaces and textured samples.
Small (SAV) and ultra-small (USAV) plates should only be used for
measurements of samples that do not completely cover the opening of the larger
aperture plates.
Medium (MAV) with barium coating must be used for transmission
measurements.
