A High-Accuracy Benchtop Spectrophotometer
With Konica Minolta's Optical Technology
for High Performance
and Computer Control for Easy Operation
High-speed,
high-accuracy measurements
Measurements at
wavelengths from 360 to
740nm at 10nm pitch are taken in approximately
0.6 seconds. Konica Minolta's optical technology
ensures high absolute- value accuracy and
repeatability, and extremely strict quality control
provides higher inter-instrument agreement and
reliability.
q
Illumination/viewing geometry
meets ISO and
DIN standards for di:8
°
, de:8
°
(diffuse illumination/8
°
viewing angle) geometry and also conforms to CIE
and ASTM standards for d:0
°
(diffuse illumination/0
°
viewing angle) geometry.
w
Pulsed xenon lamp light source
provides high
stability, long life, and excellent repeatability on
dark and high-chroma colors.
e
6-inch integrating sphere
has a powdered
barium sulfate (BaSO
4
) coating with superior
optical characteristics.
r
Double-beam feedback system
monitors the
light emitted by the xenon lamp and automatically
compensates for changes in brightness or spectral
characteristics.
t
Flat holographic grating
efficiently separates
the light by wavelength to provide higher
repeatability for dark colors.
y
Silicon photodiode array sensor
quickly
converts the light separated by the grating to
electrical currents.
CM-3720d (Whiteness Model)/CM-3730d (Paper Industry Model)
UV cutoff filter switching (CM-3720d, CM-3730d)
Cuts off UV components having wavelengths of 420nm or less emitted by the light source. Useful for eliminating the effects
of fluorescence when measuring fluorescent materials having excitation wavelengths below 420nm.
Enables easy switching to normal measurement using illumination including ultraviolet radiation.
Low-illumination setting (CM-3720d, CM-3730d)
Reduces illumination level to one-fifth. Reduction of light quantity can eliminate triplet influences, which may occur
occasionally when measuring fluorescent materials at the normal illumination level.
Opacity jig (CM-3730d)
Enables easy switching of the background between white and black and ensures paper position does not shift during
opacity measurements.
Various measuring functions
u
Switchable between SCI and
SCE measurements
SCI (specular component included ) measurements
minimize the influence of surface conditions on
measured values, making it suitable for CCM
applications. SCE (specular component excluded)
measurements correspond closely to professional
visual evaluation.
i
Changeable measurement areas
Select measurement areas of 3
×
5mm,ø8mm, or
ø25.4mm according to the application.
o
Variable UV
The amount of UV included in the illumination can
be controlled in 1000 steps for measurements of
fluorescent materials.
!0
Transmittance measurements
The spectral transmittance of liquids or of specimens
in sheet or plate form can be measured using
di:0
°
, de:0
°
(diffuse illumination/0
°
viewing angle)
geometry.
Demands for higher accuracy and more analysis capabilities have been increasing,
particularly from R&D professionals. In response, Konica Minolta has utilized its long experience in optics and color measurement
to create the Spectrophotometer CM-3700d, a high-accuracy benchtop spectrophotometer suitable for not only research
and development, but also for quality control or CCM applications.
