Microscopy in the classroom

11/11/2020 10

  • Microscopes of all types have made their way into educational environments

https://webcdn.leica-microsystems.com/fileadmin/_processed_/d/2/csm_Buffalo_State_College_student_microscope_classroom__e881e96f55.jpg

Compound light microscopes are the most common type of microscope found in classrooms today.

  • Simple
  • Low cost
  • Readily available
  • Small footprint

The Compound Light/Optical Microscope (OM)

11/11/2020 11

  • Reflection of photons off a surface

yields a true color image

  • True color with large fields of view
  • Max magnification is 1,000X (10x100)
  • Limited depth of focus causes image

blur from out of focus planes

slide-12
SLIDE 12
  • You cannot look at things smaller than what you’re looking at them with
  • Examples:
  • Optical techniques: 400-700 nm lateral resolution limit of ~0.2 mm
  • SEM: wavelength of electron, more importantly, spot size of electron beam
  • AFM & Profilometer: end radius of tip/stylus

The Scanning Electron Microscope (SEM)

11/11/2020 13

  • Interaction of an electron beam with a

surface provides an image

  • Grayscale with large fields of view and

best in class depth of field

  • Wide magnification range. Tabletops

up to 300,000x

  • Elemental Identification also available

New Phenom Desktop SEM UI is ideally suited for remote access

  • Optical microscopy provides a true color image while SEM provides a range of

f grayscale values Optical Microscope Scanning Electron Microscope

➢ SEM's z-contrast provides value added in a variety of applications Low z residue

  • SEM offers best in class depth of

f fi field

➢ Increased depth of field enables rapid inspection over large lateral areas. ➢ SEM is very commonly used as a defect inspection instrument.

Comparing OM to SEM in Practice

11/11/2020 16

  • SEM offers substantially higher resolution than OM

➢ The ~1,000x-20,000x range opens a vast array of applications for SEM ➢ Big picture: putting SEM on the resume is valuable to the student
