Spectralon® – Color and Fluorescence Reflectance Standards
Labsphere Color and Fluorescence Standards are made out of Spectralon, a high reflective, PTFE-based material that is resistant to heat, humidity and exposure to high levels of radiation, making them ideal for usage as optical standards. Those are available in two sizes of 1,25” and 2” diameter with reflectance values ranging from 99% to 2%. Standards are sold individually or in sets of two, four or eight standards with a defined choice of colors. Each standard is packaged in a durable holder with a protective cover and comes in a storage box.
