Microprint Slide v1

I can’t figure out how to view the microprint slides on the foldscope. It works fine under a regular microscope! I’ve viewed the guide, I’ve tried putting space slides, I’ve used different microprint slides, I’ve used different foldscopes (I have a class set), I’ve tried using my cellphone, I’ve done it opposite than what was recommend (spaces slides on opposite side, slide backwards), I’ve tried using different light sources – nothing!

What am I doing wrong?

I can view other things just fine, but not the microprint slide.

    Is the microprint slide opaque?

    What do you actually see when you look at the microprint slide with the foldscope? Is it dark? Sorry I am not familiar with the microprint slide.

      Hi Jay,

      You can see the product here: https://www.foldscope.com/user-guide/#microprint

      They came with the class set as a product to be used for practicing student viewing, focusing, and panning skills.

    Interesting, I have not used or seen one before, not in any of my kits. 🙂

    It says that it is metallic on the “front side” I assume that the microprint is translucent, is that the case? Is it like little tiny stained glass windows? Can you see light through the print with the naked eye?

    Are you using the LED illuminators or holding the Foldscope up towards ceiling lights or the sky?

      It was not a part of the deluxe kit I received as a teacher and my coworker who ordered the regular kit didn’t get one either.

      I can’t really tell if the microprint is translucent (which may be part of the problem). I’ve shined a light through and it is hard to tell. I’ve used the LED illuminator, held it to the sky, used a cell phone flashlight, and even held it to the sun (I know, I know).

      The slide works just fine on an AmScope at 40x magnification. With illumination from the bottom, the images and text are clear, but there’s no color. With illumination from the top, the images and text come through in color.

      It’s like the light needs to come from the front to illuminate the reflective surface (it’s like a holographic sticker), but that doesn’t really make sense to me if students are supposed to look through the lens and practice using a foldscope.

        Hmmm that is interesting, I was wondering about the transparency and front vs back illumination issue. It is interesting thet the images on the Foldscope figure “Viewing the Microprint Slide” shows the logos in color https://www.foldscope.com/user-guide/#microprint

        It does not say in the txt anything about needing top illumination… hmmmm

        There is an e-mail address in the FAQ: info@foldscope.com

        You might need to try that. Sorry I couldn’t provide an answer.

    I am guessing that you are just seeing black, is that correct? The metallic part would not let any light through and the logo part is probably very small given the magnification of the Foldscope. Is there a way to make sure you have the microwriting in line with the lens? The images seem to have a tiny smudge on them https://www.foldscope.com/user-guide/#microprint (or my computer screen needs cleaning…) I am guessing that is the viewable area and it might be tiny… so aligning it with the lens could be the trick.
