Question about Wesco WS7 Microscope

1 Answer

Double vision I recently took apart my WESCO 3000 series microscope to fix a slipping adjustment on the zoom control. After taking it apart to far, removing the lenses from the little shafts. I put it back together and now the left eye and right eye see something different. The left eye image seems to be a little bit larger on up to the left and the right eye image is slightly smaller down to the right. So when you look through both lenses you go cross eyed. Not sure how to fix?

It looks like when you took this apart you did not alignt the lenses properly, there should be a locating groove or stub which these lenses should fit to... it looks like they are pressing against the stub but are not located properly, hence the distortion. try taking it apart again....when you put it back together again the fault may have gone.

It is unlikely that you needed to go very far with the tear down. You are brave. Put it back together and take it in for servicing.

Why is my presser foot lever loose?
The presser foot lever is very loose and not moving the bar (foot lever). There is probably either an adjustment not set correctly or a screw that needs adjusting or replacing.

  1. In many apps, you can zoom in or out on specific items. For example, you can double-tap or pinch to look closer in Photos or expand webpage columns in Safari. You can also use the Zoom feature to magnify the screen no matter what you're doing. You can magnify the entire screen (Full Screen Zoom) or magnify only part of the screen with a resizable lens (Window Zoom). And, you can use Zoom together with VoiceOver.
  1. Go to Settings > Accessibility > Zoom, then turn on Zoom.
  2. Adjust any of the following:
    • Follow Focus: Track your selections, the text insertion point, and your typing.
    • Smart Typing: Switch to Window Zoom when a keyboard appears.
    • Keyboard Shortcuts: Turn on keyboard shortcuts to control Zoom.
    • Zoom Controller: Turn the controller on, set controller actions, and adjust the color and opacity.
    • Zoom Region: Choose Full Screen Zoom or Window Zoom.
    • Zoom Filter: Choose None, Inverted, Grayscale, Grayscale Inverted, or Low Light.

  3. If you use iPhone with a pointer device, you can also set the following below Pointer Control:
    • Zoom Pan: Choose Continuous, Centered, or Edges to set how the screen image moves with the pointer.
    • Adjust Size with Zoom: Allow the pointer to scale with zoom.
  4. To add Zoom to Accessibility Shortcut, go to Settings > Accessibility > Accessibility Shortcut, then tap Zoom.
  1. Double-tap the screen with three fingers or use accessibility shortcuts to turn on Zoom.
  2. To see more of the screen, do any of the following:
    • Adjust the magnification: Double-tap the screen with three fingers (without lifting your fingers after the second tap), then drag up or down. Or triple-tap with three fingers, then drag the Zoom Level slider.
    • Move the Zoom lens: (Window Zoom) Drag the handle at the bottom of the Zoom lens.
    • Pan to another area: (Full Screen Zoom) Drag the screen with three fingers.

Microscope backlight has suddenly become intermittent

The "pot" really adjustable electrical resistance feed in the bulb directly of through a triac is most likely showing intermediate contact between the resistance coil and "slider" - it will have to be replaced.

The autofocus is not working. I tried going to manual focus and this won't work either. Also when I try to zoom out it will only let me go about a qauter of the way then it stops, and won"t zoom out...

Was it recently dropped or bumped in any way? The focus and zoom motors are not activating or limiting. It could be misaligned or slipping gears. Listen for motor running as you press the appropriate function - such as manual focus or zoom. If you hear anything then the motor are running but not adjusting the lens - therefore the gear is loose and/or the motor is slipping. It must be taken apart to repair.

I recently tried to turn my Casio Exilim EX-S6 when the lens won't come out all the way. I turned it off and back on and the lens came out all the way but did not focus. I than repeated the off and on and...

Mine does the same thing. I took it apart and found that one of the microscopic plastic gears in the zoom assembly had a few teeth broken off. If you like to tinker and if you can find a replacement assembly, it shouldn't be too hard to fix. I'm still looking for parts, though.

Image appears double and slighly off when viewing

I was having a double vision problem with my Barska 10-30X50 zoom, 195FT/100YDS binoculars. One image was always higher than the other. This was tolerable at low zoom, but was further aggravated the more I zoomed in. I found that I could grasp both barrels and twist them in opposite directions (one side up, the other side down) and force the two images to merge--but that was a strain and an unpleasant viewing experience. As an experiment, while looking through the binoculars, I grasped the far end of the right barrel and twisted it on its axis. Nothing happened at first, but after a certain amount of resistance it began to rotate independently of the body. Lo and behold, this shifted the barrel's axis, and the image for that eye moved vertically! I turned it until the two images merged, and now I'm thrilled to say that the problem is solved! I don't have a clue if this would work on any other brand or model, but it's worth a try!

Putting it back together

In 1965 I did the same thing with a Nikon single focal length lens my F Photomic. This lens was far more simple then a modern AF zoom lens. I had to bite the bullet and pay a camera repair man to fix the lens. He told me that had I not tried to fix the lens myself, the repair would have cost 1/4. The only answer to your question is to take it to a camera repair man and get a quote. I would check the quote against the price of your lens on E-bay and use that to determine if you want to fix your lens or replace it.

By the way, it is very rare for dirt between elements to be so problematic that it results in a degradation of picture quality.
