## Overview

The Labsphere Spectralon Diffuse Reflectance Standards set includes four 1" calibrated standards with reflectance values of 2%, 50%, 75%, and 99%, designed for accurate optical measurements in various applications.

## 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. This set contains calibrated diffuse reflectance standards: 1" - 2%, 50%, 75%, 99% - NVLAP ACCREDITED
