CM 10 Tristimulus colorimeter with high spatial resolution
Precise lab measurement and direct display of color coordinates
The CM 10 from the Instrument Systems Optronik line is a precise tristimulus colorimeter for a wide range of light sources. It features an impressively high signal dynamic range and a wide measuring range of up to 600 klx. The colorimeter head of the CM 10 contains four silicon photodiodes with full-glass filtering for the Xred, Xblue, Y and Z tristimulus functions. This permits particularly precise correction.
Readings are displayed at the touch of a button in the different CIE coordinate systems. For white light analysis a corrected color temperature is calculated in K. In its Y-channel the instrument also displays a reading in lux, and due to its excellent V-lambda correction of the Y channel it meets the requirements of a Class L photometer pursuant to DIN 5032-7 (2017).
CM 10 – Product details:
- Determination of color values in the X-Y-Z (CIE-LAB), x-y-Y (CIE-LAB), u-v-Y (CIE-UCS 1960), u’-v’-Y (CIE-UCS 1976) coordinate systems and correlated color temperature in K
- Wide measuring range over six decades; maximum display value 600 klx; display resolution 0.1 mlx in the most sensitive measuring range (applies to Y-channel)
- High spatial resolution through Ø14 mm light entry area (advantageous for goniometric measurements)
- V (λ) alignment ≤ 1.5% in the Y-channel; 4 silicon photodiodes with precision photocurrent amplifiers; thermostat stabilization to 35°C
Perfect for measurements with high spatial resolution
The CM 10 can be flexibly used for a wide range of applications, e.g. as a standalone measuring station, together with a goniophotometer or an integrating sphere for simultaneous determination of luminous flux and color coordinates. Furthermore, in conjunction with a standard illuminant A projector unit it can be used for determining the color of retroreflection in accordance with ECE R3 or R 27.
In contrast to other tristimulus colorimeters, the detector has a light entry area of only 14mm and is thus particularly suitable for applications in which an emphasis is placed on measurements with a high spatial resolution, e.g. in the analysis of color deviation along the cut-off line of vehicle headlights.
