The Spectrophotometer proves to be a good multitasking device. It is designed to measure the color spectrum of various objects. Light consists of a broad spectrum of colours which are not always purely white, black or blue. A light-source illuminates an object, which then absorbs part of that light and reflects another one. That reflected light can be then detected by a sensor in order to determine the reflected wavelengths and thus calculate its colour. Spectrophotometers are often applied in areas of quality control in industrial sectors. Spectrophotometer of the PCE-CSM series are applied especially in industries where the characteristics of colors play a big role. Whether it is dental technology, painting industries or for the production of plastic bags, the Spectrophotometer PCE-CSM 4 is an ideal product for quality management and thus assure highest reliability, whenever it is important to assure a certain standard in optic quality. 

The Spectrophotometer supports an ergonomic design and features a user-friendly menu navigation. The Spectrophotometer PCE-CSM 4 has a large measuring aperture of 20 mm. The supported colour spaces of the Spectrophotometer PCE-CSM 4 are CIEL*a*b*C*h, CIEL*a*b and CIEXYZ. Thus the Spectrophotometer is designed for application in professional industries.  

Another advantage of the Spectrophotometer of the PCE-CSM series is that it supports a vertical justification. This means that the whole device does not need to be placed on the object to analyse, but only the part with the sensor in it. The industrial perspective of it is that this method allows the measuring of damp objects, textiles and even food. The Spectrophotometer PCE-CSM 4 is therefore ideally applied for measurements of e.g. meat, bananas or tomatoes. Due to the software "CQCS3" that is included in the delivery, the measured data can be read out on a computer or laptop for a digital overview.

The L*a*b color space

Colorimeter NR145 and NR20XE: Color Spaces

Here you can see the colour space L*a*b. This colour space covers all colors that are visible with the naked eye. L=100 stands for white and L=0 for black. "a+" and "a-" or "b+" and "b-" stands for the colour contrasts red, green, yellow and blue.
