Looking for a ring light for my microscope. There are a lot of options, some of them are really cheap, others are expensive. I am wondering is there any difference between the cheap one and the expensive one. For instance this light from Euromex and the Chineese option from Aliexpress. https://www....

I have worked with thin sections some years ago.. I am retired now and just use the microscope as a hobby... I don't take it as serious as I once did...

I guess it depends upon whether a person views "color rendering" as critical... To me it is not very important...

Hi Mary, The idea is to have one between the light and the subject and another between the subject and the eye.. I use a second hand camera filter over the light so it is easy to rotate to get extinction.. This works also: https://www.ebay.com/itm/Polarizing-Film-EDUCATIONAL-GRADE/252617982312 BillT

"Electric nano-wires often connect species of bacteria , one to the mesh of others..and indeed utilize electric signals for group responses to habitat conditions."... BALONEY!!...

You watch too much "Avatar"...

WELCOME!...

"Moreover, the LED is said to be 1W. I am in doubt about the brightness you will get, especially for darkfield, should you wish such modality." Replacing the 1W LED with one of a higher wattage should prove very little problem... I have found them all very simple to do.. You just have to keep up wit...

Hi lubobul, Take a look at this Amscope on Ebay... https://www.ebay.com/itm/AmScope-40X-2500X-LED-Lab-Trinocular-Compound-Microscope-w-3D-2-Layer-Mech-Stage/143133511670?epid=2255438810&hash=item21536c0ff6:g:UyAAAOSwpYxcFTLW:rk:21:pf:0 It is a trinoc and seems to have better features than the Optika...

Don't worry about negative comments here on your choice... I would just look at AmScope.. I think you can get the same or similar setup from Amscope usually for less money.. Chinese scopes are fine for hobby use unless you are a boring perfectionist that leads a very dull life..

Gears and gear technology is an art and a science... At one time there were two basics systems of generating gear teeth.. The MAAG system developed in Switzerland where the cutter is shaped like a rack, and the Gleason system developed here in the USA, where the cutter was circular... It has evolved...

Welcome, and dive in!... Both feet!...

"species interactions on earths huge biomes are symbiotic/beneficial"...Not always the case... It IS the "dismal" 'struggle of the garden' which Charles Darwin emphazied)... Dr.Lynn(it is Lynn, not Lyn) Margulis's statements are nothing more than unproven theory and speculation... Nature is a fight ...

"Do different species organize themselves differently? Do some secrete poison to clear away other species?".. YES!!... They sure do!... I read somewhere where two species of bacteria were competing for growing space.. One defeated the other by attacking and wiping them out with generated Hydrogen Pe...

"I wouldn't use the 35mm camera, never really liked film, even before digital becam available."

Since you never really liked film, what did you use??..

BillT

Will be anxious to see what you come up with...

BillT

This looks like it would be a lot of fun!...
