Handheld Spectrophotometer / BYK-Gardner spectro2guide 45/0

spectro2guide 45/0

The Revolution in Color Measurement:
Color, Gloss, Fluorescence

The spectro2guide 45/0 spectrophotometer represents the next step in the evolution of color measurement. Just like its predecessor, color and 60° gloss are measured simultaneously. Completely new is the prediction of color stability by measuring like a fluorimeter with monochrome illuminations.

Measurement of Fluoresence

Traditional color measuring instruments work with both a polychromatic illumination (e.g. tungsten lamp, xenon flash etc.) and a monochromatic detection (grating, filter array etc.). As commercially available spectrophotometers use different light sources, the measurement results will be different for specimens containing fluorescent ingredients. Different light sources show different spectral power distributions and therefore, the amount of illuminated light exciting the fluorescent components will be different. Depending on the specific excitation range, a particular fluorescent component will absorb the excitation light and emit the fluorescent light in the longer wavelength range. Consequently, the amount of emitted fluorescent light will differ dependent on the amount of the excitation light. Thus, the measurement results of spectrophotometers with different light
sources cannot be compared.

In practice, fluorimeters are used to evaluate fluorescent samples. These setups use monochrome illumination and thus, can detect the amount of fluorescent light independently of the specific light sources.

The monochrome illuminations need to be calibrated to the same level. For colorimetric calculations under different illuminants this calibration must be done in respect to each illuminant type.
The spectro2guide is a revolution in color measurement. It unites a fluorimeter and a portable spectrophotometer in one instrument. For illumination a full spectrum, white power LED and 12 monochromatic LEDs are used. The detector is a mini aturized spectrometer detecting light in the range of 360 – 760 nm.
By comparing the characteristic spectral power distributions of the white power LED and the 12 monochromatic LEDs, it is able to detect, allocate and quantify the fluorescent light. In addition, the spectro2guide is able to calculate how the specimen will look like under different illuminants (“Fluorescence metamerism”) and it can calculate how the color will change when the fluorescence has degraded (ΔEzero).
It is the first portable spectrophotometer on the market, which can be used for a reliable Quality Control of fluorescent specimens.

Color Stability Prediction
Excited. Emitted. Shifted.

The combination of a spectrophotometer with a ﬂuorimeter opens up completely new perspectives to control color quality and guarantee color stability.
Lightfastness is analyzed with proprietary calculations predicting the color change with total color difference DE as well as individual color component deltas (∆L, ∆a, ∆b, ∆C, ∆H).
The excitation and emission range of fluorescent behavior is displayed with the slider function in smart-lab.

Brilliant Color Display
Swipe. Touch. Measure.

As for mobile phones, there is a trend towards ever-larger displays. The new spectro2guide is completely in line with this trend offering a 3.5” color touchscreen – the largest on the market. An icon-based menu, colorful data tables and graphics ensure an intuitive smart phone like operation. As you are used to, you can touch or swipe with your fingers – it even works when wearing gloves. Alternatively, you also can use a stylus, which is enclosed in the housing – always handy.

Smart Docking Station
Park. Charge. Control.

As first handheld spectrophotometer on the market, the spectro2guide comes complete with a docking station offering an auto diagnosis and an automatic calibration reminder. This is made possible by the built-in white checking standard, which is well protected in the docking station. Moreover, the docking station automatically charges the instrument.

Preview with Camera
Strike. Score. Save.

An integrated camera shows a live preview of the measurement spot. To ensure precise positioning and to prevent false readings on imperfections or scratches, the measurement spot is magnified by a factor of 4.5:1.

It is so easy – just press the measurement button halfway and the live preview is active.
