Products > Analytical > Fluorescence > QE-2100 series
QE-2100 series measure absolute quantum efficiency. Any form of samples, including films, powders, liquids, and solids can be measured. Integrating hemisphere and high sensitivity detector adopted in QE-2100 series minimize the effects of stray light in the ultraviolet region and remove re-excitation. Various analytical functions and easy operation encourage you to obtain absolute values of phosphor characteristics.
