Integrating sphere Barium coated sphere.
Industry standard.
Measurement
Geometry
Diffuse illumination, 0º
viewing
Conforms to the instrument specification
found in ISO 2469 standard.
SP2000 Spectral
Analyzer
Proprietary dual-
channel holographic
grating. 256-
photodiode linear
arrays used for oth
the reference and
sample channels.

Aperture Plates
Three aperture plates, with openings of different sizes, are included as standard accessories. The
identification is engraved on each plate.
Aperture Plates Designations
• Extra-Large Area View (XLAV)
• Small Area View (SAV)
• Ultra Small Area View (USAV)
Below are aperture plate specifications:
Aperture

Sample Area
Illuminated
XLAV 30mm 34.0 mm
SAV 5mm 9.0 mm
USAV 2.5mm 6.5 mm
NOTE
The area illuminated is always 4mm greater than the diameter measured, to reduce
translucency errors.
Tips for Aperture Selection
• Always use the largest possi le aperture size.
• Small (SAV) and ultra-small (USAV) plates should only e used for measurements of samples
that do not completely cover the opening of the larger aperture plates.
