Polarizing Nikon: Crossing Pols for Asbestos Fibers
Read the Edited Video Transcript for ‘Polarizing Nikon: Crossing Pols for Asbestos Fibers’
Hi, this is Chad with Munday Scientific. Today we’re going to talk about the Nikon E400 polarizing scope.
We already have a couple of videos on the E600 and the E400, specifically about the polarizing portion of these microscopes, but this one is a little bit different. So, we want to show you one quick thing.
Key Features
Michael’s going to come in here and demonstrate. On this scope, you have the 360° analyzer right here, and you also have the wave plate. The wave plate has to be aligned in the light path, and it has to line up with the polarizer.
The Polarizer and Condenser
A lot of times, you’ll see polarizers on this style of scope. That’s what we want to highlight. This is a standard flip-out condenser, but notice how it won’t come out? Usually, you can slide that out, but the reason it won’t come out is because it has the polarizer attached on the bottom.
This polarizer is what you rotate. Here’s your polarizer to cross the poles. It just snaps into the bottom of the condenser, and then you can rotate it like this.
Crossing the Poles
Once you get the poles crossed, you can insert the wave plate into the light path, and you’ll see a nice pink hue through the microscope. You can also shift the color spectrum, which is really useful.
Applications
This setup is commonly used for asbestos work, and this particular scope is excellent for that application. The customer who bought this microscope wanted a quick explanation of how to cross the poles, so that’s what we’ve shown here. We were able to save them money by using this polarizer instead of a different version.
Closing and Contact
Overall, it’s a great scope. If you have any questions, you can email us at —that’s “Munday” with a “U.” Or give us a call at 919-775-5596.
