Description
Essential requirements:
• Research-grade inverted microscope chassis, stage, transmitted light illumination, eyepieces etc
• Microscope should be capable of phase and differential interference contrast transmitted light methods.
• Objectives 10, 20, 40 and ~60 or 100x optimised for epifluorescence observation and DIC, 20 and 40x objectives optimised for UV excitation for Fura 2 (@340 & 380 nm, if different from standard epifluorescence objectives), additional 20 and 40x for phase contrast.
• Epifluorescence light source to provide illumination for cellular physiology studies (excitation suitable for a range of dyes including fura 2) should include software controlled shutter, or equivalent, to control illumination and synchronise to image acquisition.
• Epifluorescence light source for general epifluorescence imaging (2 and 3 above) if different
• Ability to mount both epifluorescence illumination systems and switch between physiology and high-resolution epifluorescence imaging modes
• Monochrome camera suitable for real-time imaging cellular physiology
• Monochrome camera for high resolution general epifluorescence (if different from above)
• Ability to mount both cameras and switch between physiology and high-resolution epifluorescence imaging modes
• Image acquisition and analysis software suitable for running cellular physiology studies
• Image acquisition and analysis software suitable for general epifluorescence studies. Ability to combine fluorescence images to produce composite images, ability to undertake image analysis/cytometry measurements of fluorescently labelled specimens.
Desirable requirements:
• Motorised control of microscope operation
• Additional image analysis options for analysis of standard histopathology tissue sections
Other:
• If all capability is not possible on one microscope chassis then would consider two systems.
