For use over the UV,VIS and NIR spectral regions
Reflectance standards

Overview

A selection of diffuse reflectance standards in different sizes of Zenith Polymer® white and greyscale standards. All Zenith Polymer® products show an ideal Lambertian behavior and a constant reflectance throughout the wavelength range from 250nm to 2500nm. The calibrations are traceable to NIST/PTB and can individually be made by a Perkin Elmer Lambda 19 high performance spectrometer.
Other optical features of Zenith Polymer® are the high reflectance of more than 98% in the UV/VIS and NIR range as well as the mechanical and thermal stability. Thermal stability up to 250℃ and a simple mechanical handling makes the porous PTFE to an ideal conductor of laserbeams or an excellent reflectance surface.
