The Olympus DSU (Disk Scanning Unit) represents a breakthrough in spinning disk confocal technology. The DSU disk contains a pattern of slits that creates a virtual pinhole as the disk spins at 3,000 rpm. Designed to optimize the tradeoff between confocality and light throughput, the DSU uses an arc lamp illumination source for maximum excitation wavelength flexibility at a reasonable cost.
Spinning Disk Confocal Specifications
| Confocal scan method | Disc rotation method |
| Maximum scan speed | Image acquisition less than 33msec/frame |
| Camera | Recommended camera: CoolSNAP HQ, Orca® ER |
| Excitation wavelength | 350nm - 700nm. Wavelengths of less than 430nm at naked eye observation and DSU observation may reduce the confocal effects. |
| Fluorescence wavelength at observation |
At less than 450nm, use our HQ filter for observation |
| Observation mode | Exchange between confocal and non-confocal modes can be performed through the software |
| ND filter for excitation | An ND filter will be inserted automatically at the exchange of confocal and non-confocal modes |
| Electromagnetic shutter for excitation |
Can be controlled through the software |
| Microscope attachment | Intermediate attachment method (other cameras can be mounted on C-mount intermediate attachment) |
| Temperature and humidity |
10°C - 35°C, 30 - 80% |
