Flow cytometer is a kind of instrument which can analyze and sort the cells or biological particles in a fast and straight-line flow state. It has become a very important instrument in the diagnosis of blood cells and cancer. The optical principle is that a light spot of about 22 * 66 μ m, which is slightly larger than the cell diameter, is irradiated on the fast flowing cells carrying fluorescein marker in the flow cell. The fluorescent signals, which represent different substances and different wavelengths in the cell, are generated by laser excitation. These signals are centered on the cell and radiate to a 360 degree solid angle to produce scattered light and fluorescence signals. Fluorescence signals of different wavelengths are sent to different electronic detectors through optical system. Then, the complete parameters of cells or biological particles can be obtained.
The application of HB Optical in the precision interference filter of flow cytometer
Wavelength selectivity of polychromatic laser
HB Optical can provide precise optical filters for multi-color lasers such as UV, blue, green and yellow green to meet customers' needs. The specially designed film can block the laser line to od6 or above, so as to obtain the perfect test effect.
Higher test sensitivity
After special design, combined with APS plasma and RF ion assisted coating technology of HB Optical, the transmittance of precision optical filter is improved, which means that the instrument developers can obtain better test sensitivity.
10 year service life guarantee
HB Optical selects imported coating materials and cooperates with leading coating manufacturing process to ensure long-term stability of performance. The product is tested by the test parameters of mil-std-810f under severe service conditions (10 cycles), and the product performance reaches almost permanent stability.
Stable level of mass production industrialization
HB Optical has the largest filter purification production line in China. It adopts the top test equipment of American vatian and PE and its patented gluing and packaging equipment. Under the control of ISO9001 quality assurance system, it ensures stable and large-scale supply capacity.
