This is a small monocular/instructable about my discovery, when playing with lenses. The dimension of this small monocular are about 15x10 mm ... but I'm not sure about the magnifying ratio. I would say something about 3-6 times (or maybe more).
Step 1: What Do You Need...
You need just 2 main items :
1. lens from the small SPY camera
2. lens from a (broken) green laser pointer.
Then you need :
3. something that would hold the lenses together in a fixed distance to get a sharp picture (in my case = washers)
4. glue gun
Step 2: Lets Do It ...
In my case, I had luck, because the lens from the laser pointer fit exactly in the hole of the washer. And by previous experiments I realised, that I need cca 4mm distance between the two lenses to get a clear-sharp image.
So I used 2 washers. On one I glued the camera lens ... and in the other one I put the laser lens. The good thing about the washer was, that the lens hold there really good (without any other corrections or changes to be made) ... and you can still adjust the lens a little bit - to push it deeper in the hole or opposite.
- I do apologize for the NOT sharp picture. I made this pictures with my Nokia N95. The phone focused on surrounding area, and I didn't realised it :(
Step 3: Results ...
Here you can see two pictures. I made both of them from the same distance. You can see how powerful this small monocular is.
I think, this could be used on spy cameras that need to have a look at long distance & by the same time still remain small.
Thank you ...
