Life in dark water

A sample of water that is in a jug that I am using to root a plant cutting. The jug itself is opaque white and yet there is life. Taken at about 400x. Some small microbes in there.

Got a new scope!

Well, secondhand anyway...Spotted this Apex Practicioner in Cash Converters the other day and had to put a deposit on it. It needed some work (stage and condenser were wonky) but we got there, and for £60 it was a bit of a bargain. Not bad optics either, tho I have some spares now (including a 100x ...

Danged if I can find Cyclops' exact light amongst the zillions https://tinyurl.com/ph5gr4j in the universe of itty-bitty LED spotlights.

Re: UV light for microscopy?

I am thinking of doing the same as well. You can put a right angle prism (or even a microscope slide at 45 degree) under you condenser (with hypotenuse face facing up towards condenser). Then shin UV torch to it and observe/focus via camera (or computer) screen. Algae may produce faint red light un...

UV light for microscopy?

I have a small UV LED torch (flashlight) and I was wondering what applications I could put it to in regards the microscope. It's visible so not a blacklight but fluorescent objects glow under it, as do white objects.

Re: Present for a kid

The trouble with starter scopes is they nearly always concentrate on high magnification, 'up to 1000x magnification ' in big letters, and without a good light set up they're useless. My first scope was a cheap nasty plastic affair with 600x highest power, but it was so dim with just the mirror it wa...

Re: Tip of a Horsetail frond at various magnifications

Does it have a brand name on it? There are a bunch of similar lamps on the web, but I haven't yet found that particular one yet. No brand on it, I think it's custom made http://img.photobucket.com/albums/v11/Dawnrider/PicsArt_1439575217134_zpsf6pcp45z.jpg http://img.photobucket.com/albums/v11/Dawnr...

Where did the LED light come from? It looks like it produces a powerful beam.
I was sent it by someone on facebook, it is incredibly bright!
