A number of introductory and advanced microscopy lectures can be found on the iBiology Microscopy Course website.

Be sure to check out the lectures by HCBI Faculty Director Professor Jeff Lichtman:

Description: Light has properties of particles and waves. Understanding the wave nature of light is essential to understanding the workings of a microscope. This lecture describes Huygens Wavelets, constructive/deconstructive interference, and diffraction.

Point Spread Function
Description: An infinitesimally small point appears in the microscope as a spot with a certain size, blurred in the Z-direction and with concentric rings around it. This "point spread function" reveals many of the optical properties of your microscope. This lecture explains why and how the microscope images a point as a point spread function.

Description: The resolution of a microscope can be defined as the smallest distance at which two small objects can still be seen as separate objects.  This lecture discusses various criteria for resolution, the factors that influence resolution in the lateral and axial planes, and how to sample an image adequately using a camera or confocal microscope, such that the full optical resolution is retained.

Choosing the right camera for your microscope
Presented by: Doug Richardson, Director of Imaging, HCBI
Description: Selecting the right camera for your microscope, or more specifically, the correct camera for your specimen, can be a difficult task. Recent advances in technology have flooded the market with hundreds of choices from cheap webcams to very expensive scientific digital imaging devices. This webinar will outline some key considerations when selecting a camera for your project. Topics will include: pixel count, pixel size, color vs. monochrome, CCD vs CMOS, spectral response, noise, and read-out time.
