Sustainability is a principle of action in which economic, ecological and social action are in the foreground.

With this in mind, we at MICROBOX act sustainably and considerately and consciously say “YES” to Germany as a business location. We develop and produce on site in Bad Nauheim and purchase 90% of our materials from regional suppliers. This guarantees the quality and longevity of our products, which also have extremely low energy consumption. If possible, we also offer the revision of old scanning systems to the latest status as an alternative to buying a new one − an investment that pays off for our environment and our customers.

The components of the book2net scanning systems are connected to one another with screws. These can be easily removed during recycling and all components recycled separately. The steel housings are also fed directly back into the material cycle. In this process we only work with certified companies.

It is our aim to create attractive offers for our customers, which, however, are never at the expense of the environment or social and labor law requirements.

Spectroscopy refers to a group of physical methods which decompose radiation according to certain properties such as wavelength, energy, mass, etc. The intensity distribution that can be read is called a spectrum. The quantitative measurement of these spectra is done by means of a spectrometer and, the graphical representation as spectrograms.

Spectroscopy is one of the non-invasive, non-destructive scientific examination methods used in art technology, particularly in the field of damage analysis or forgery detection.

Numerous materials used in works of art, such as inks, pigments, etc., can be identified on the basis of their interactions with electromagnetic radiation. These interactions can be detected and assigned to specific materials; thus, the spectrum becomes material-specific, a quasi-optical fingerprint. Storing such reference spectra in reference databases supports the work of scientists in their research.

For art technological analyses, visible (Vis=visible) light, radiation in the infrared (NIR) and ultraviolet (UV) range, and X-rays in particular are used.

Spectral colors describe the color impression of the human color perception that light of a certain wavelength produces. They are created when white light is refracted through a prism. This causes the light to split into the seven spectral colors visible to the human eye, i.e. into monochromatic light of a specific wavelength that cannot be further subdivided. If these spectral colors are combined again, white light is produced once more.

In nature, this phenomenon is best observed using the example of a rainbow. Sunlight is refracted by raindrops as if through a prism, causing the spectral colors to appear in the form of a rainbow in the sky.

The spectrum of light visible to humans lies between the long-wave end of ultraviolet light (360 to 380 nm) and the short-wave beginning of infrared light (780 to 820 nm). The perceived hue changes smoothly from violet to blue to green to yellow to red.

The seven spectral colors are violet, blue, green, yellow, orange, red and indigo. They can be assigned to the following wave ranges:

• Violet: 380 to 430 nm
• Blue: 430 to 490 nm
• Green: 490 to 570 nm
• Yellow: 570 to 600 nm
• Orange: 600 to 640 nm
• Red: 640 to 780 nm

The color indigo is located in a middle range between the blue and the green wavelength range.
