## Overview

Labsphere’s 2-inch Spectralon Diffuse Reflectance Standard offers an industry-leading 99% reflectance with exceptional spectral flatness from 250 to 2500 nm. Its highly Lambertian surface and NVLAP accreditation make it the ultimate choice for precise, reliable spectrometer calibration in professional laboratory settings.

## Description

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. Individual Calibrated Diffuse Reflectance Standard, 2" - 99% - NVLAP ACCREDITED
