stly make sure that you’re using the focus ramp (component A4) properly! The focus ramp is, as the name suggests, a ramp that is thick on one end and thin on the other. Sliding the focus ramp from left to right changes the distance from the lens from the sample, shifting the focus. To start at the lowest focus, put the thin side of the ramp between the lens and the sample. To adjust focus, push toward the thick side while viewing your sample until you can see the sample clearly.
Secondly, make sure you are viewing objects that are translucent, or allow light through. Completely opaque objects can not be viewed using transmission light microscopy.
Third, errors in the assembly process can result in difficulty focusing. Please review the videos at https://www.youtube.com/playlist?list=PLnO8NcEb6LFy1p0rCVBfHY0JUgBswRC4m to ensure you have properly built your Foldscope.
Please visit our youtube tutorials page at https://www.youtube.com/playlist?list=PLnO8NcEb6LFy1p0rCVBfHY0JUgBswRC4m. for help with assembly and usage!
No you can keep it!
Yes! You can use isopropyl alcohol to clean your lens!
First, it depends on the type of sample, if it is a dry sample like the clothing fiber or grass seeds one coverslip is fine, it it is a wet sample we recommend sandwiching the sample.
Did your receive a deluxe kit? If so we would recommend using the transparent tape on the other side of the cover slip to sandwich between the transparent tape and the clear coverslip sticker, thus saving your coverslip stickers!
If you received the basic classroom version with no tape then we recommend using two clear coverslips for best results with wet samples.
Hope this is helpful!
First I would say visit our YouTube channel and view how to prepare slides at https://www.youtube.com/watch?v=vOq-8cORMd0&list=PLnO8NcEb6LFy1p0rCVBfHY0JUgBswRC4m&index=4&t=9s
Our paper slides are made out of the same material as the Foldscope, thus are waterproof and can be used to make wet slides, using the regular slides you have purchased will work as well!! They will fit perfectly into the slots on the foldscope!
