ACCURATE
LOW LUMINANCE
• The luminance and chromaticity of display can
be measured as fast as 20 times per second
(maximum), enabling faster Gamma
measurement.
• Precise measurement can be obtained at low
luminance, enabling lower luminance and high-
accuracy contrast measurement.
Range of luminance for chromaticity measurement
: 0.1 to 1000 cd/m2 (Universal Measuring Probe)
0.3 to 3000 cd/m2 ( Small Universal Measuring Probe )
• Accuracy of ±0.002 for White, ±0.004 for R,G,B.
(Chromaticity)
• CIE 1931 Standard Observer XYZ Filter.
• Matrix measurement enables high accuracy for
not just white, but for monochrome colors as well.
• The measurement position can be easily
confirmed by pointing function.
• Short measuring distance of 30 mm enables
compact measuring system.
• Precise measurement can be obtained without
the influence of the outside light by short
measuring distance and the rubber hood
(standard accessory).
• Special optical design limits acceptance within
narrow angle of aperture. It eliminates the
influence of viewing. Acceptance angle: ±2.5˚
(Universal Measuring Probe) , ±5˚ (Small
Universal Measuring Probe)
• 4-digit display for chromaticity enables more
precise data readings.
• Expandable up to 5 measuring probes. (Requires
expansion board CA-B14)
• USB connection provided as standard, so it can
be connected even to computers without serial
ports.

Optical System Features
The CA-210 uses a special optical system suitable for providing
measurements of LCD panels.
The main components of the optical system are the objective lens, optical
fiber block, on-chip lenses, and sensor. The light from the light source is
focused onto the receiving window of the optical fiber block. The focused
light is mixed inside the optical fiber block and split into 3 parts, which are
then guided to the receiving areas of the x, y, z sensors. Here, the light is
further focused by the on-chip lenses onto the sensors themselves.
Low-Luminance Measurement
A key point in making it possible to accurately take measurements at low-luminance levels is to
minimize the light loss in guiding the received light to the sensors.
In a conventional system, the received light passes through the objective lens and is focused
immediately on the 3 sensors (x, y, z sensors). A problem with this method is that some of the light
is focused on areas other than the sensor, so the light loss is large.
The CA-210 uses optical fibers, so the light loss due to transmission of the light to the sensors is
relatively low compared to conventional methods. Specifically, the light received by the lens is
focused on the optical fiber block receiving window. The light then passes through optical fibers
directly to on-chip lenses, which focus the light onto the sensors. As a result of this, light
transmission loss is eliminated and measurements at low luminance levels are made possible.
Narrow Viewing Angle/Uniform Viewing Angle
When a person looks at a display, they view the emitted light within a relatively narrow angle.
Because of this, in order to obtain measured values which correspond well with the luminance and
chromaticity perceived by a person, it is necessary for the measuring instrument to have the same
narrow viewing angle. In addition, since LCDs have viewing-angle characteristics, measurements
at different viewing angles will result in different measured values. IEC 61747-6, which defines the
measurement method for LCDs, specifies that the viewing angle of the measuring instrument for
evaluating LCDs should be within 5°. (The viewing angle is shown by θ1, θ2, θ3 and ψ1, ψ2, ψ3.)
The CA-210 has a viewing angle of 5°, and so meets the requirements of the IEC standard.
For a conventional measuring instrument, when the measuring head has been set so that the
measurement axis is perpendicular to the surface of the emitting surface of the measurement
subject, differences in the measurement position do not result in great differences in the viewing
angle itself (shown as θ1, θ2, θ3 in the figure), but if we look at the incident angle relative to the
normal to the emitting surface (shown as a dotted line in the figure), we see that the maximum
angles (shown as θ'1 and θ'3 in the diagram) are very different. At the edges of the measurement
area, light from far outside the viewing angle is received.
By using a special optical system in the CA-210, the angle of the received light is symmetrical
about the normal to the emitting surface for every point within the measuring area (φ27 mm). Since
the viewing angle of the CA-210 is 5°, the light received would be only the light within ±2. 5° relative
to the normal to the emitting surface (shown as a dotted line in the figure).

This table is based on the most popular method for controlling emission intensity for
each display type.
(∗1) Measurements of displays using certain control methods are not possible. For
details of measurement compatibility, contact your nearest Minolta representative.
Examples for which measurement is not possible:
• Displays which use PWM, etc. for control of emission intensity.
• Displays with backlights which emit intermittently.
• Displays which write black for each frame,
etc.
(∗2) Although the CA-100Plus can handle the emission intensity variation, the
instrument has a wide acceptance angle which makes it unsuitable for
measurements of LCDs with strong viewing-angle dependency.
Recommended
Measurement possible with restrictions, but probes marked with are recommended
Measurement not possible
LCD Flicker Measuring Probe and Small LCD Flicker Measuring Probe are unsuitable for Measurements of CRTs.

This is an example of gamma adjustment system. User can
create adjustment system by PC Software for Color
Analyzer CA-SDK which comes as standard accessory.
Software controls CA-210 and pattern generator to obtain
color and chromaticity data with each out put level. After
calculating correction factor of gamma curve, software will
write the look up table of coefficient to monitor firmware.
The white balance adjustment system can be constructed
by a similar method.
Construction of Gamma Adjustment System
User's own matrix correction factor is set to the memory
channels by measuring three monochrome colors (R, G, B
and W) of known values and setting the obtained calibration
values (xyLv) and emission characteristic to the instrument.
Once this factor is set,a the measured values will be
displayed after correction by this factor and output each
time measurement is taken.
Performing matrix calibration enables high-accuracy
measurements of displays that provide colors through
additive color mixing of three monochrome colors (R, G and B).
Since the matrix correction factor obtained from Minolta's
calibration standard has been set, measured values
calculated based on this factor will be acquired when this
instrument is used for the first time since shipment from the
factory.
