About Fresnel lens:
Can you cut the lens
into a small size for me?
No, we can't. You have to cut the lens yourself.
Do you make 1 meter
custom Fresnel Lens?
No, we can't. Because it is difficult to pack with strong
enough protection, besides the shipping company will not
accept such large package.
Can your fresnel magnifying
sheet be put directly on the page to magnify object?
All the magnifying sheets should keep a focal distance to object

without focal length, it is just a regular sheet which can
not magnify object.
