What is the difference between Polorized Light, Darkfield, and Brightfield Illumination Methods?
Polarized Light are light waves which are uniformly aligned in one direction. Polarized microscopes improve image contrast and quality. A perfect microscope for a quantitative , transmitted, polorized light application is the LOMO POLAMtm-L 213 Series Microscope. This microscope can be configured for both research and routine applications, as well as for teaching environments.
Darkfield is an illumination method used to examine specimens which cannot be distinguished from the background. Components include a dry darkfield condenser for low magnifications and any
low magnification objectives. An oil darkfield condenser is used for higher magnifications. Higher magnification oil objectives must have an iris.
For a live blood microscopy application a Darkfield microscope is just as effective as an inverted metallurgical microscope.
A perfect microscope for live blood microscopy would be the LOMO Laborascope LA-MI-AL-3000
Trinocular Microscope. This microscope is perfect for the lab and clinical applications. This microscope offers all of the advantages of the contrast techniques-Brightfield, Phase Contrast, Darkfield, and Epi-Fluorescence. It is an excellent choice for Photomicrography.
Brightfield is an illumination method in which light is reflected off the specimen and passed through the objective to the eyepieces. A perfect addition to your laboratoy is the LOMO Invertoscope Series microscopes.The LOMO a LA-MI-INVERTOSCOPE has all of the contrast techniques-for your application, such as Brightfield, Phase Contrast and Polarization. In this series of Brightfield microscopes an additional contrast technique to consider may be DIC.
Whichever microscope that you select from the LOMO collection you can expect nothing but the very best in Optics performance. You will want to have this microscope in your lab.
Remember not with everything but with most things in life you get what
you pay for!
