Description:
For field work or unclean environments, the white reflectance standard can be a good option. Its Spectralon diffusing material can be smoothed, flattened and cleaned if it gets pitted or dirty. Reflectivity is 99% from 400-1500 nm and >96% (250-2000 nm).
Feature:

• Diffusing materials – choose from PTFE or Spectralon standards
• High reflectivity over broad range – >95% reflectivity from 250-2200 nm
• More options – additional Spectralon reflectance standards and targets also available
