Improved Detection Optics Enable Unsurpassed Sensitivity and Resolution for the Detection of a Wide Variety of Fluorescent Signals
Optical Detection System with High Precision and Simple Optical Alignment
- Laser beams are directed to the flow cell, without the use of optical fibers, in order to achieve maximum excitation intensity.
- Fiber optics corresponding to each of the excitation lasers are positioned immediately adjacent to the unique hybrid flow cell.
- The fiber optics collect and direct the fluorescent signals from each laser to the detectors for that laser, so as to minimize any crosstalk, so that the excitation laser beams may be positioned very closely to each other.
- The lasers are fixed to the optical bench and the alignment is so stable that it allows the removal and replacement of the flow cell/nozzle assembly (for cleaning), with virtually no adjustment of the optical alignment.
- The nozzle that is used to form the fluid jet for sorting is fixed to the flow cell tip and allows high speed droplet sorting.
- The flow cell unit may be easily removed and replaced (a matter of a few seconds) to facilitate direct cleaning of the inside of the flow cell as well as to remove any difficult clogs that may occur in the nozzle. Cleaning may include the use of the ultrasonic cleaner that is supplied with the JSAN.
*Removing and replacing the flow cell unit may occasionally slightly displace it from its original position. Any optical alignment adjustment that nay be required are easily performed in a matter of a few seconds and return the performance of the system to its optimal state.
