Microscope help: how to look at an object from the side way?

  1. Apr 2, 2007 #1
    Does anyone know how to look at a object from the side way on a microsocope?
    I've tried using a mirror, but the focus distance (to the object in the mirror) was too small.
    I've also tried to google "90 degree microscope objective lens" or something like that, but couldn't find anything.

    Any help is appreciated.

    Thank you.

    A mirror is the only way to do it, assuming that you can't simply rotate your sample. For short working distances (high mag objectives) this is not trivial. You might want to consider an alternative way of imaging your sample.

    Thanks a lot for the reply!

    But is there 90 degree "bended" objectives out there on the market?

    It depends on the object, what kind of object?

    I'm not aware of any specialist optics that can achieve this on a standard microscope.

    And if you use a mirror, you will need to use a "first surface" (or "front surface) mirror. Your laser lab or optics lab should have one they can loan you, or you can buy them from Edmond Optics, etc.

    Sorry for the ultra late reply.
    I need to look at a droplet of mixture from the side.

    I've been using mirror for awhile now.
    The image isn't really that great, but probably it's good enough for now.

    Thanks for everyone's help!

    Okay, this may be a stupid suggestion, but here it goes anyway:

    You're looking at a droplet, so it's pretty homogeneous throughout the drop, I'm guessing. The only reason that it'd look different from the side is because of gravity.

    If you rotated your microscope 90 degrees (hah, this could be a real challenge for some microscopes!), you may be able to see what you want.

    This, of course, is a very "ghetto" method, and probably won't be taken seriously. But hey, if it works, then awesome!!

    Yes, I also thought about that. But with the microscope I'm currently using, it is impossible to do that without some major modification. Plus, I can't guaranty its function after the modification (and it's not mine).. haha
    I need to look at it from the side because I've added something to the droplet, and applying voltage and stuff.. and the gravity's affect in the setup, of course.

    But thanks for the suggestion anyway.
