Details

SmartFluo-QY is designed based on single photon counting technology. SmartFluo-QY is based on the optimization design of optical system for nearly 15 years, and using a single photon counter as a data acquisition device, so it has the ability to detect very weak fluorescent signals, and the signal to noise ratio of water Raman is > 3000:1. SmartFluo-QY can achieve wide spectrum detection range, and can meet the requirements of various research and industrial applications such as physics, chemistry, biology, medicine, semiconductor materials, environmental science and other scientific research and industrial applications.

Challenge sensitivity limit -- "single photon counting technology"Application areas:

"Single photon counting" is using the feature of natural discretization of the output signal of the photomultiplier in weak light. The precision pulse amplitude discrimination and digital counting technology are used to extract the weak light signals submerged in the background noise. When the weak light is irradiated to the photoelectron cathode, each incident photon emits an electron with a certain probability (quantum efficiency). This photoelectron is multiplied by the multiplier system. Finally, a current pulse is formed in the anode circuit to form an electric pressure pulse through the load resistance. This pulse is called a single photon pulse. The single photon counting technique can detect a single non overlapping photon energy pulse, and work by precise means of identification, thus realizing the purpose of detecting the weak signal of the single photon level.

Spectral resolution and excitation light intensity control

The excitation and emission spectrometers of SmartFluo-QY are 300mm focal length high resolution spectrometers. The excitation source can adjust the luminous flux of 5%-100% flexibly through the automatic aperture, the minimum bandwidth of the excitation wavelength can reach 0.1nm, the fluorescence detection can discriminate the 0.1nm fluorescence peak, and the excellent mechanical performance ensures the wavelength repeatability up to 0 .1nm.

Synchronous measurement

In synchronous measurement, both excitation and emission monochromators are scanned synchronously the user preset offset, which can be used to distinguish and identify fluorescence components in mixtures.
