Can the lense be cut? My project needs a circular piece around 5 inches in diameter. What tools would I need to cut it, if possible?

I think one can easily cut it with good household scissors though I haven't tried it. The Fresnel pattern is circular and centered in the sheet of material.

Not for sure I bought it for making camp fires but as cheap as they are you can give it a try. I believe a regular pair of scissors would work to cut it

They are about the size of a sheet of printer paper (7 X 10 1/4)and are plastic. Very flexible. I haven't tried to cut one but I would think any good pair of scissors would cut it easily as they are only slightly thicker than printer paper.

Absolutely. The raised ridges are concentric and should help guide a razor knife. Tools should be a razor knife or scissors and something circular to use as your guide. It will cut easily, like cutting 3-4 sheets of stacked paper.

I suppose you could use a pair of heavy duty shears, but you lose the effect of the lens. The less surface area you have, the less light focused on the point of heating. If that's not a big issue, the lens is just thick plastic. Also, you have to use the center of the lens, or you won't get a good spot. I would look for a smaller lens to buy first, before I cut a big one to fit.

Btw, for magnification I don't think you need to take it from the center. Test this first for your project. If you can take your circular piece from the edge you can save a good portion of the remainder. Possibly get two 5" pieces from one sheet.

A circular saw (or SkillSaw) would rip it to pieces! I used a razor knife that had an extendable blade. It's a very soft material that can crumble easily

The paperwork with the lens kit says to extend the lense and screw on the filter. Although I am not an engineer, that sounded like a prescription to break either the threads on the lense/filter or break the camera, so I declined the attempt. I contacted the company and was told "We shipped what you ordered" so I gave them a bad rating and will not do business with them again.

At the lens end it is 1.5" in diameter, in the middle area it is aprx 1" in diameter - you might be able to mount it with a two piece clamp type mount around the middle but it would not slide into a 1" mount from either end. There is also the belt clip which does not appear to be easily removable (without cutting it off) which may interfere with the mount alignment. I think it could be done but not without a bit of re-engineering of an existing mount.

Its big enough to cover the opening of a 50mm f1.8 lens. Havent measured the disks. This is a nice set but the plastic is really hard to cut for new shapes in the blank ones even with Xacto tools. To make your own, i would recomend thick black construction paper. Its inexpensive and easy to use.

It is not clear but you can see through it. It has a blue tint. I think you could cut it but the plastic is pretty thick. I would suggest heavy duty scissors like fiskars or something but yes you can cut it.

the short answer is no,however you could try to take it to a eye glass store that has their own lab..and talk to their people that work with plastic lens..anyother way would cost more than the light..paul

This would not be my tool of choice for making the type of cut you describe, although, in an emergency you might be able to rig something up that would be servicable. A circular saw would definitely be preferable especially in terms of smoothness.

Being a plastic material, I suppose it could be cut. Because they are so inexpensive, my recommendation is to buy several.

There is no specific diameter that it cannot cut. Templates are always valuable in this respect, though. There are many templates available - especially if can get access to drafting or art supply outlets. If not, one can conceivably be creative and make/or use ones own template. As mentioned in a prior answer, this "gadget" is a freeform cutter; can only cut thin sheets of paper and requires a bit of practice to be able to cut "clean" circles (or any other shape, for that matter).

I cannot answer your question as we have not tried to remove & replace the lense. However, this question has been asked before and the respondant said that it is possible.

Im not exactly sure but one thing I know for sure is you will need a reducer. This camera will magnify the image the same way a 5mm lens would. The big question you want to know before you buy this is if your telescope can move the camera close enough to the focal plane.

I don't know if it can be cut. I was just very disappointed in both sizes that I ordered (small and the large). The ad says they'll stick together - yet mine didn't. I'd get them together and they'd come apart. I wish that the jewelry could stand upright instead of laying on its side. Also, I would like to have had a clear top. That's just my preference. Wish I hadn't wasted my $$ but I needed something and this item sounded perfect.

I'm not sure as I've never tried that but it does have a separate eyepiece, so there could well be some sort of digital imaging device that would fit in there instead of a glass lens. Good luck!

Make the shape in cardboard and use as a guide. Then use a very sharp knife to make the cut. Best regards, C2CSAFETY best sourse for Pelican cases.

You could cut it to whatever dimensions suit you. Just use a good heavy duty pair of scissors or a straight edge and razor knife. It's only plastic so it's easy.

Technically, you can make 30mm circles. That was the primary reason I bought it as I needed to make many for markers for a project. However, if you have a design you are trying to cut out, it is very difficult to center the device over the image so you cut it out. As noted in other reviews, you really need the products stencils (sold separately) in order to ensure you don't cut through your design.
