This motorised inverted widefield fluorescence microscope features a fast and sensitive sCMOS camera for fluorescence detection and a colour camera for transmitted light. Hardware autofocus ensures continuously stable focusing throughout long imaging experiments. The system is suitable for a wide variety of widefield imaging experiments (brightfield, phase contrast, multi-channel fluorescence) on live or fixed samples.
Available techniques:
- Transmitted light imaging (brightfield, phase contrast)
- Widefield multi-channel fluorescence imaging with a fast and sensitive camera
- Long-term time-lapse imaging (with hardware autofocus)
