Specular Spectral Reflectance - These SRMs are intended for calibrating the reflectance scale of integrating sphere reflectometers used to evaluate materials for solar energy collectors and to calibrate reflectometers used in evaluating the appearance of polished metals and metal-plated objects.


SRMs 2011, 2013, 2015, 2017 and 2021 are now being supported by Calibration Service (Service No. 38060S). Click here for further information:

Infrared Reflectance (solid form)

Optical Rotation (powder form) - SRM 17f is intended for calibrating or checking polarimetric apparatus.  In aqueous solution, the optical rotation of SRM 17f is value assigned at four wavelengths.  

Photography (chart form) - SRM 1010a is used to test the resolving power of cameras or of whole microcopying systems. It consists of 5 charts printed photographically on paper, that have 26 high-contrast, 5-line patterns ranging in spatial frequency of 1 mm-1 to 18 mm-1.

 


204.2(4) - Optical Rotation (powder form)

Optical Rotation (powder form) - SRM 17f is intended for calibrating or checking polarimetric apparatus. In aqueous solution, the optical rotation of SRM 17f is value assigned at four wavelengths.
