Microscope polarisant 400x
This interactive tutorial simulates 360-degree rotation of birefringent samples through crossed polarizers in a polarizing microscope. To operate this tutorial, first select a sample from the Choose A Specimen pull-down menu. Next, use the Angle slider to rotate the sample stage through 360 degrees. The image will change depending on sample orientation, with the birefringent crystals changing.

Polariser la lumière consiste en quelque sorte à la filtrer pour ne conserver qu'une seule direction de vibration (celle du filtre). Ce principe est utilisé dans le microscope polarisant : Un premier filtre polarisant fixe (le polariseur) polarise la lumière dans une direction (verticale ici) : la lumière qui le traverse est dite polarisée.

The technique improves the resolution and color details of smartphone images so much that they approach the quality of images from laboratory-grade microscopes. The advance could help bring high-quality medical diagnostics into resource-poor regions, where people otherwise do not have access to high-end diagnostic technologies.

Microscope polarisant virtuel Cette appli web simule un microscope polarisant, et permet l'observation de lames ou de zones de lames d'intérêt pédagogique. L'intérêt est de pouvoir compléter les fiches d'identification des minéraux ( dispo sur le site de l'académie de toulouse ), afin de faciliter l'identification, qui reste difficile.

What are the different types of microscope? The main types of microscope are: light microscope, compound microscope, confocal microscope, scanning electron microscope and transmission electron microscope. Light and compound microscopes are illuminated by visible light and can magnify between 200 and 1000 times respectively.

The average numerical aperture of 20x and 40x polarized light objectives is usually 10 to 25 percent higher than those for ordinary microscopes because observations of conoscopic interference patterns require high numerical apertures. Objectives designed for polarized light microscopy must be stress and strain-free.

The virtual microscope stage is graduated in 10 degree increments and allows rotation through a full 360 degree turn of the sample. As the sample is rotated, birefringent elements of the sample undergo intensity changes (from brilliantly illuminated through total extinction) that reflect their orientation with respect to the virtual microscope.
