The DeltaVision Elite from Applied Precision is an inverted wide-filed fluorescence microscope for live cell imaging.
Key features
- Olympus IX71 inverted microscope
- CoolSnap HQ2 cooled CCD camera
- Fast excitation switching
- Laser module for TIRF/FRAP (The objectives currently only support the FRAP applicaiton)
- Motorized stage and focus
- Hardware based autofocus
- Incubation Chamber (C02, himidity and temperature control)
- On-site Deconvolution
Objectives
all objectives are from Olympus

Lasers
Diode Laser: 405 nm (100mW), 488nm (50mW), 514nm (50mW), 561nm (50mW) e
The lasers can be used for FRAP. TIRF is not possible since we currently do not have the necessary objective.
