Hi MichaelG,


Thank you very much for your comment, I forgot to explain that 100X was 10X Objective with 10X Eyepieces.

Re: A commercial or DIY smoke cell for microscopy?

Then carefully move this slide under microscope to observe Brownian Motion. Focus the microscope objective a little bit higher to see the smoke particles moving around. It will be easier to use Joss Stick as a source of smoke. The smoke in the cell will last about 1 or 2 minutes, then we have to fil...

Re: A commercial or DIY smoke cell for microscopy?

4. When we put this Smoke Cell over a microscope slide, it will be a small Smoke Cell that can be used to observe Brownian Motion. 5. To use this Smoke Cell, I setup microscope with Dark Field mode (if you have not a Dark Field patch, build one of it first). Adjust microscope brightness to about 80%...

Re: A commercial or DIY smoke cell for microscopy?

I would like to share easy DIY small “Smoke Cell” to observe Brownian Motion under microscope at 100X as follow; 1. Cut a cardboard strip about 3mm x 84mm to use it as a wall of Smoke Cell as show in the picture. This size will fit with 22mm cover slip. If the cardboard is quite thick and you need a...

Re: Dark field difficulties

Hi matt123 May I suggest you to test your set up in the Dark field like this; - Cut a normal photocopy paper in the size of standard microscope slide (around 1 x 3 inch I think). - Use your Prepared Microscope slide and set up your Dark field to the best result as you can. (Cross section of any wood...

Re: Onion Cell 400X GUF

Thank you very much Apochronaut and JimT for your comment.

I think GUF filter is usable at 400X, it can show fine details and look much better than normal Bright field illumination.

6. You may try to increase or decrease “Gradient Stop” Stop 1 and Stop 2 in PowerPoint to increase or decrease Gradient area, but I am OK for the 40% and 80% that I have used. Using UGF Filter is a trial and error approach, first step you have to fully open the condenser diaphragm and slide UGF filt...

Re: Review Amscope 60X Objective

Now the 60X Objective was in place of 100X Oil Objective and I keep the 100X Oil Objective in the box for future use. Sometime I think that, the Microscope manufacturer should put the 60X Objective in the set as option A and 100X Oil Objective in the set as option B. It may be more useful for amateu...

If I need more than 600X, I can use 16X Eyepieces to get 960X Magnification and the image quality is acceptable to me.
