Spinning Disk Confocal Specifications

The Olympus DSU (Disk Scanning Unit) represents a breakthrough in spinning disk confocal technology. Designed by Olympus, 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. The DSU is compatible with both inverted and upright Olympus microscopes, including the motorized IX81 and BX61 making it an ideal imaging system for automated Z-stack, 3-D image analysis. The water-immersion BX61WI and BX51WI electrophysiology microscopes and the entire water immersion objective line are also supported.

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%
Power	Provided through microscope controller
