Filter Wheel Multiple Excitation Systems
Our recommended filter wheel multiple excitation configuration.Our standard multiple excitation system consists of a high intensity xenon arc light source coupled to rapid spinning / stepping filter changer, and then to a fluorescence microscope via a liquid light guide. The main advantages of this arangement are as follows:
- Our xenon light source with integral igniter offers intense uniform illumination without the risk to neighbouring electronic equipment often assoaciated with this type of lamp.
- The optical adapter includes neutral density material and an iris diaphragm as standard. Provision is also made for fitting an electronic shutter, and 1" filters, in the light path.
- The filter wheel operates in spinning and rapid stepping modes, making it suitable for photometric and imaging applications. With six filter positions available it is possible to use combinations of different dyes simultaneously.
- The flexible liquid light guide serves to isolate the filter wheel from the microscope, thus ensuring that no vibration is transferred.
- For most makes of research microscope our light guide couplings can take the place of the manufacturer's own epifluorescence attachment; with a resulting benefit in optical efficiency, and a financial saving.
