Tip of a Horsetail frond at various magnifications

#1 Post by Cyclops » Thu Aug 13, 2015 3:27 pm

I found a Horsetail growing in the garden and broke off a piece, set up my LED for reflected microscopy and took some shots with my phone over the eyepiece.

Is that a mirror you are using on the stage to help reflect the light??...

Hi Cyclops,
I think using the disk as a reflector seems to help.. I might try a small mirror and see if it does anything... Anyway, It looks like dark field to me... Very good!...

Very nice, you've the prototype of a good & effective system there! Some very fine detail in the images too, good lighting has clearly helped the camera to focus well - keep it up there's some very good things going on there. :) Beautifully rich tones too.

Nice pics! I was just looking at an invasion by horsetail of the Rose Garden in Berkeley, CA.

Where did the LED light come from? It looks like it produces a powerful beam.

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.

Hi CaterpillarGuy,
It is nowhere near a "little lamp"... It is 3 watts and is incredibly bright.. So much so, you can't bear to look directly at it...

"Little", dimensionally speaking. ;-) I'm looking for the whorled fins. Do they get hot?

No brand on it, I think it's custom made

I'm wondering if I undo those 3 screws I can fit filters/diffusers:

Yes because no light is coming from beneath

Danged if I can find Cyclops' exact light amongst the zillions https://tinyurl.com/ph5gr4j in the universe of itty-bitty LED spotlights. They're mainly used for recessed lighting rather than microscopy, btw.

This one http://www.dx.com/p/e27-helical-luxeon- ... c6QsrKrS70 is very similar but is set up for a socket.
It runs on house current, but I saw others that run on 12V, either AC or DC.

It plugs into a 12v wall wart

That site shows all mains powered lights, mine runs off a 12 v adaptor

I don't know the wattage of mine but it is insanely bright! The brightness control is off and just on. There's no real control, it's all or nothing!
