inert, and washable standards have typical reflectance values of 95 to
99 percent and are spectrally flat over the UV-VIS-NIR spectrum. Spec-
tralon SRM-99 reflectance material is the most Lambertian reflector
available for use over the wavelength range from 250–2500 nm. All
reflectance calibration tests are directly traceable to NIST (Fig. 1.25).
It is used for calibrating:

• Densitometers
• Integrating sphere systems
• Optical equipment
• Photographic equipment
• Reflectometers
• Remote sensing
• Spectroscopy instruments
