LM4U - light microscopy, for you!
What is LM4U? - Briefing Abstract
Look, its not really a taught course! OK?! Its a briefing for new users and whoever else needs to know the bare essentials of light microscopy. This is not a substitute for a full "Basics of light microscopy course", but it will get you started. This very brief, "crash course in light microscopy basics", covers:
- What you need to know about light microscopy and the LMF/IPF, but never knew to ask.
- Concepts you need to know / refresh, including tips and tricks, concerning how to improve your imaging experiments and impress your RGL/PI, and TAC.
- Safety: Lasers, mercury lamps, etc.
- How to use the LMF / IPF
Target Audience:
Everyone doing light microscopy- ESPECIALLY NEW-COMERS!!!
Content
(1 slide per point)
Introduce yourself
- Who are we?
- Who are you?
Practical Microscopy Tips and Tricks
- What is a Microscope - Provdides Magnification and more importantly Resolution.
- Basic Ray Optics of a Lens.
- refraction
- Conjugate planes
- Single Lens has 2 focal planes FFP and BFP
- little microscope
- What is confocal
- Resolution
- optical resolution - Point Spread Function / Airy Disk
- Pixel Spacing (size?) Physical CCD dexels vs Picture Elements vs point scanning
- Numerical Aperture vs Magnification : Abbe/Rayleigh Resolution d = lambda / 2NA
- What is contrast? (No light = no image; no contrast = no resolution)
- Fluorescence and Stokes Shift
- Spectrum databases / viewers for planning expt.
- Fluorescence and Stokes Shift
- Detectors: CCD vs. PMT Widefield vs point detection
- Digitization
- Detector Saturation
- Objective language / reading
- Coverslip thickness is part of the objective design (#1.5 0.17 mm +- 0.01)
- Lens Immersion media
- old oil, wrong oil, wrong collar setting
- Lens cleaning
- Project Planning / Workflow
Safety
- mercury HBO lamps - explosion risk - what to do it it explodes.
- lasers (jewelry, interlocks, eye level above laser level, dont disable/defeat laser safety devices, dont look at a laser with your remaining good eye. )
- White light sources (HBO, MetalHalide etc. and Halogen) can also hurt your eyes.
