Purchased a USB digital microscope to view trichomes. It appears to work well. The material was removed from the plant and the small device was hand held to take the pictures. It is well made and ideal for my application.
This is the unit.
Ignorance is bliss. I would be happy with some, probably 30 to 40 percent. I am pleased that they are multiplying, enlarging, and easy to see with little effort.
I use a Jiusion Digital Microscope. It even takes video. I have the aluminum base too. I'm going to modify it to work on a tripod. It'll be pretty cool.
