Abstract
The description relates to a standard for wavelength and intensity for spectrometers, particularly for calibrating and testing measurement heads in spectrometers which are usable primarily in the near infrared region (NIR) of the spectrum. The standard comprises a holder and a plate body arranged in the holder. The plate body is made of transparent plastic with high strength and dimensional stability over a large temperature range. The plastic has distinct absorption bands throughout the entire NIR range and has a chemical structure and composition ensuring an extensive moisture barrier against water absorption and water release in a reliable and stable manner over time. The plate body advantageously comprises an amorphous, transparent copolymer based on cyclic and/or linear olefins.
