The device is made up of an excitation...

make various measurements such as PL quantum yield and external External Quantum Efficiency Measurement System C9920-12 Highly precise measurement of emission efficiency does not depend on the emission angle distribution characteristics by using an integrating sphere. The C9920-12 External Quantum Efficiency Measurement System is a device for measuring the exter- nal quantum efficiency of a sample by exciting the LED device with current (voltage) and measuring the number of emitted photons. Measurements of emissions versus the current applied can be made, inclusive of elements related to the...

Providing a Variety of Solutions by Combining Low-Light Observation, Spectroscopic Measurement, Optical Measurement and Image Processing Technologies. Picosecond Fluorescence Lifetime Measurement System: C11200 Fluorescence and Phosphorescence Lifetime Measurements Picosecond to millisecond fluorescence and phosphorescence lifetime are measured with high dynamic range by combining a laser and a streak camera. The results of the measurements are observed as a two-dimen- sional image made up of a wavelength axis and time axis, so it is possi- ble to visually grasp the lifetimes for each of the...
