The CS-150 and CS-160 are highly accurate tristimulus colorimeters equipped with newly designed sensors with
spectral responses that more closely match the CIE 1931 color-matching functions representing the sensitivity of the
human eye to provide measurement results that better correlate with visual evaluation.
Bright viewfinder makes it easy to target
desired areas of measurement subjects.
Backlit display is easy to read even
in dark places, and is automatically
switched off during measurements.
Automatic mode automatically sets
the measurement time according to
the brightness of the target.
Easy-to-hold grip.
Smooth focusing during measurement.
The included software allows the meters to be controlled from a PC. Repeated
interval measurements can be conducted for a specified number of times at
specified intervals, measurement data can be displayed on graphs or lists, and
data can be sent to spreadsheet applications.
Measurable illuminance range:
• CS-150:
Corresponds to 0.15 - 999,900 lx
• CS-160:
Corresponds to 1.5 - 9,999,000 lx
* This illuminance measuring
method does not conform to
DIN or JIS standards.

*Measuring distance is the distance from the measuring distance
reference plane.
Illuminance adapter
enables illuminance to
also be measured.
C-mount CCD camera adapter
enables the viewfinder to be
monitored from a distance.
This adapter allows an industrial
C-mount CCD camera to be
attached to the viewnder so that
measurements including the view
through the viewnder can be
monitored from a distance or recorded.
* CCD camera not included.
* The x¯ (λ) CIE 1931 color-matching function has two peaks, a small one in the short-wavelength region (often labeled x¯
1
(λ)) and a larger one in the long-wavelength
region (often labeled x¯
2
(λ)). In conventional tristimulus colorimeters, the x¯ (λ) sensor has a spectral response only for the long-wavelength region x¯
2
(λ), and the
data for the short-wavelength region x¯
1
(λ)is calculated from the z¯ (λ) sensor. But the CS-150 and CS-160 have spectral responses that more closely follows the CIE
1931 color-matching functions, and directly measures using the x¯ (λ) response in both the short-wavelength region x¯
1
(λ) and long-wavelength region x¯
2
(λ), so the
resulting instrument spectral response more closely matches the CIE 1931 color-matching functions for the human eye.
