On ours, we had this same problem and all we ended up having to do was turn the light bulb up towards the black plate and it comes on, then turn the bulb down towards the feet of the microscope and it goes back off.

The dimmer switch is not working it wont light up or dim at all put in a new light bulb

A good idea would be to check the wiring by taking it apart. if the wires are bad, you must get new ones and solder them to the light socket and the battery holder making sure not to cross the positive and negative wires.

What is the other types of microscope ? how do they differ from a compound microscope ?

Compound Microscope
  • Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.
Dissecting Microscope
  • Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.
  • A Scanning Electron Microscope uses electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.
  • Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.

My tasco microscope light will not turn on and the battery pack

sometimes when a battery causes corrosion inside something, you can clean off the springs or contacts where the battery goes. if i can, when that stuff happens i use sandpaper or something like that to clean the contacts. you cant always get sandpaper where you need it though. just try to find something to like scrape stuff off if its on there

Light on the Vivitar 900x microscope does not function

It's not uncommon for these low end microscopes to have wiring issues right out of the box. My guess is a faulty contact at the switch or at the socket, as these microscopes work on a very simple electrical circuit.

You can try to disassemble the microscope yourself and see if you can find the disconnected wire, shouldn't be too hard. The other options are to send it back to walgreen's and try to exchange it, have it sent back to directly to vivitar for warranty repairs, or have a technician check it for you.

Same problem, tried flipping it every which way with no luck - both the light itself and the arm that hold it. Finally, when trying to change the batteries, I noticed that they battery housing was odd: usually the positive end of the battery is against the node, and the negative end against the spring. This is true for one of the batteries, but for the other one has to turn it backwards, so that the positive end is against the spring. This is the only time I have seen a battery go in that way, and so naturally I had not looked for -/+ labels, but had just put the batteries in the housing in the way one would assume they go. When I changed the one around (and it was labeled that way), it solved the problem and the light came on. I don't know if I just got lucky, but you might as well try and see if it works for you.
