CS-150 / CS-160 Spot Luminance Colorimeters

Konica Minolta CS-150 Spot Luminance Colorimeter

The Konica Minolta CS-150 and CS-160 are portable, non-contact, tristimulus spot colorimeters with a a 1° and 1/3° field-of-view respectively and convenient SLR reflex viewing optics for targeting of the measurement spot. They are our least expensive, portable colorimeters for display and sign measurements and report brightness (luminance) in cd/m2 and CIE colour temperature and chromaticity in the 1931 xy colour space system. The CS-150/160 replace the previous-generation CS-100A and offer an enhanced spectral match to the CIE standard XYZ colour matching functions for improved measurement accuracy.

Spot measurement of colour and luminance in a portable instrument

The CS-150 and CS-160 are lightweight, compact and battery powered luminance and colour meters for the measurement of a wide range of luminance conditions and non-contact measurement of colour. A successor to the CS-100A, the new instruments offer improved features and usability. These next generation instruments provide an increased measurement range and a sensor that more closely matches the CIE 1931 colour-matching functions.

To provide the most accurate measurement of luminance, the relative spectral response of the measuring instrument should perfectly match the sensitivity of the human eye for photopic vision, as represented by the CIE spectral luminous efficiency V(λ). Alongside improved usability, the CS-150 and CS-160 feature an improved correlation to V(λ) and a greatly improved measurement range up to 999,900 cd/m2 (CS-150) and 9,999,000 cd/m2 (CS-160).

The CS-150 and CS-160 feature the same user-friendly features as the popular CS-100A:

  • SLR (single lens reflex) optical system and pistol grip design gives the operator precise control over targeting and ensures that the viewfinder shows the exact area to be measured, even at very short distances.
  • The measured luminance value is displayed inside the viewfinder whilst full measurement data is shown on the large external monochrome display.
  • The optical system is virtually flare-free, eliminating the influence of light from outside the measurement area.
  • Areas as small as 0.4mm diameter (CS-160) can be measured when using the optional close-up lenses (for information on measurement areas please refer to the CS-150/160 brochure).

Main Features

Lightweight and portable: the battery powered CS-150/160 weights just 850g (excluding batteries) and comes in a hard case for easy transportation.

SLR (single-lens-reflex) optical system: this ensures that there is no difference between the area indicated in the viewfinder and the actual measurement area.

Spot measurement for small target areas: the 1° acceptance angle of the CS-150 can measure areas with a diameter as small as 14.4 mm (at a distance of 1,014 mm); using the optional close-up lens, this can be reduced to diameters as small as 1.3 mm (at a distance of 205 mm). The 1/3° acceptance angle of the CS-160 can measure areas with a diameter as small as 0.4 mm (with close-up lens 110 attached).

Provides tristimulus colour data: the colour of the object inside the measuring spot is measured without the influence of the surrounding area and without needing to touch the sample.

Colour-difference measurements: once a target colour has been set (by direct numerical input or measurement), colour-difference measurements can be made, facilitating quick and easy colour management.

Data memory for 1000 measurements: with USB 2.0 communication, you can connect with a PC to send measurement data and receive control signals. The instrument can also be powered by USB cable, ideal for use in measuring rigs or when working with a PC/tablet computer. Data-management software CS-S20w is included as a standard accessory

10 user calibration channels: the CS-150/160 can be calibrated to a user reference light source which can be used to further reduce errors and improve inter-instrument agreement when using multiple devices.

Areas of Application

Besides the measurement of absolute values, the instrument can also display values relative to a defined standard (target). That way differences in brightness and colour on large surfaces or similar items can be quickly ascertained.

The CS-150/160 can measure the luminance and colour values for all types of light sources including signal and traffic lights, airport runway lighting, lamps, LEDs and so on. The wide measurement range of 0.01 cd/m2 to 999,900 cd/m2 (CS-160 0.1 cd/m2 to 9,999,000 cd/m2) and adjustable integration time ensures that the CS-150 or CS-160 can be used for most luminance and chromaticity applications.
