5. Smartphone holder
Attach the smartphone holder to the eyepiece.
The suction cups must be clean and free from dust and dirt. A slight moistening is helpful.
Now press your smartphone on the retaining plate and make sure that it is properly secured.
As a backup, you should secure it with a rubber strap.
Smartphones with a rough surface will not hold as good as smartphones with a smooth surface.
Now start the Camera app.
The camera needs to rest just above the eyepiece. Center the smartphone exactly over the eyepiece, so the
image can be seen precisely centered on your screen.
In some cases you need to adjust with the zoom function to display the image fullscreen. A light shading
at the edges is possible.
Take the smartphone carefully off the holder after use.
NOTE:
Make sure that the smartphone can not slip out of the holder.
Bresser GmbH assumes no liability for any damages caused by a dropped smartphone.
6. Condition and prepare viewed objects
This microscope features transmitted light, so that transparent specimens can be examined.
If opaque specimens are being examined, the light from below goes through the specimen, lens and eye-
piece to the eye and is magnified en route (direct light principle).
Some small water organisms, plant parts and animal components are transparent by nature, but many oth-
ers require pretreatment — that is, you need to make a thinnest possible slice of the object by hand cutting
or using a microtome, and then examine this sample.
