Labsphere - Spectralon Diffuse Reflectance Standards : 1" - 99%

الوصف

Spectralon Diffuse Reflectance Standards can offer the highest diffuse reflectance values of any known substance. These durable, chemically inert standards can have typical reflectance values ranging from 2% to 99% and are spectrally flat over the UV-VIS-NIR spectrum. All Spectralon materials are optically flat to +/- 4% over the range of 250 – 2500 nm and +/- 1% over the photopic region of the spectrum. Spectralon Diffuse Reflectance Standards are highly Lambertian, with Spectralon SRM-99 reflectance material being the most Lambertian reflector available for use over the wavelength range from 250 – 2500 nm.
