Learning about the condenser

I posted my condenser frustration on the Forum on Microbehunter.com. The folks there are very generous with sharing their knowledge and suggesting places to find information.

I found enough information and diagrams online to help me understand the condenser and how it works. I’ve been practicing to learn how to make the most of it.

Ordered polarizing lenses that fit my filter holder. Up to now I’ve been using the plastic lenses from 3D glasses that came with our TV. They work, but the plastic is vulnerable to scratches.

I’ve been concentrating on viewing various chemicals and solutions. It’s time to take a break from that and get back to living things.

Condensers – a minor rant

As a rank beginner, it has not been easy to learn about condensers. My student scope did not have one.  My big excitement about having a condenser on my new scope was because it has a filter holder. I wanted to learn about how to use it.

My internet searches brought up all kinds of technical information with diagrams of a condenser’s construction, and about cones of light. Somewhat interesting but at this stage of my learning curve, I don’t care about technical details.  Maybe later, when I’ve learned more.

I am interested now only in how to get the best images. I finally got useful information from a December, 2008 Microbe Hunter Magazine article. At last!

I wish that knowledgeable people would take pity on those of us who start out with very basic equipment.  Please, someone publish on line a  “Condensers for Dummies”. Or maybe I’m the only dummy.

First Darkfield Experiment

Darkfield has been a mystery to me. I’ve seen plenty of photos taken in darkfield; but didn’t really understand how or why to use it. There are plenty of darkfield filters available online but my lack of understanding made me reluctant to make even a small investment.

Then I came across a Microbe Hunter video about these filters and how to make one. As always, these videos are filled with lessons and practical information.

It seemed that it was fairly simple to make my own. I located transparent plastic, used a filter as a template, cut it out, and cut a small circle of black paper attached with double stick tape to be the stop. It’s not pretty, but it works. 

YAY!

I’m not ready for Rheinberg or Oblique filters but they look fascinating. For now, I’m still taking baby steps.
