## Questions & Answers

**Q: What is the focal length? Thank you.**
A: The groove pitch is 0.5mm. The focal length is 320mm

**Q: Cant I cut this into a smaller sizes with an exacto knife or box cutter?**
A: Wow, a bunch of wrong answers. Not only is it possible to trim the edges and use the center portion, it is even possible to cut it into sections, and each section will continue to function. The only difference is that a lens cut from a location not in the center will need to be held over to one side. If it isn't apparent what the total effect will be, just imagine that you took the lens and covered half of it with paper and tape, and then covered have of the remaining rectangular piece, so that once again you have a square section. Obviously this section has to be held to one side, and it probably wouldn't work very well for a reading lens. But you certainly could still use it to start a fire.

**Q: what is the magnification**
A: Unlike with a telescope or a microscope, a magnifying lens's magnification varies as you move closer to or farther from the object you are observing.  I can tell you that it can project the light from the sun to a point about 1/2" in diameter.  This is a concentration, compared to the size of the rectangular lens, of almost a factor of 500.  That doesn't mean that you can see somethings 500 times its size by looking through the lens.  What is means is that it has a huge amount of light gathering surface and focuses it on a very small spot.  This may not be the answer you are looking for; but I can't think of a better way of stating it.  It can ignite a fire in a second or so.

**Q: How can it be used for 'do it yourself solar cooking'?would this size be bigenough to cook?wouln't it need reflector to reflect to the bottom of pan?**
A: I have seen a fresnel lens used to cook (at burning man). They pointed the beam at a cast iron and cast iron pans are good at dispersing the heat evenly across the pan. It probably took a while for it to heat up but it was definitely working.

### ⭐⭐⭐⭐⭐ Works great
*by M***S on August 9, 2025*

Works great. Exactly as it should. Affordable, durable, very light, about 12 inches long, easily magnified the solar light and concentrated it to a laser which cooked anything to over 1200 c.

### ⭐⭐⭐⭐⭐ Perfect magnifier. Good price
*by B***N on March 4, 2025*

Used it for a coding project where the text could not be magnified. Made it extremely easy to see smaller text.

### ⭐⭐⭐⭐ Magnifiers a good deal for the price!
*by K***H on October 30, 2015*

I ordered these because it seems to me that whenever I need one to read small print when I'm out somewhere, I don't happen to have one in the bag that I'm carrying with me at the moment. So now I can stuff one in every bag I've got to have one at the ready whenever I need it. They do the job nicely. The text is bigger and more than clear enough for me to read whatever I need to read. I'm very nearsighted and I'm a contact lens wearer, and with my lenses in, reading small print is out of the question without either reading glasses or a magnifier. And frankly the magnifier fits it my purse much more easily than a bulky pair of reading glasses. So these are perfect for when you're on the go. I recommend keeping each one in the little plastic sleeve it comes in to protect them from scratches because to offer a 10 pack at that price, naturally the material they're made of is not as substantial as you'd find in magnifiers of this type that are sold individually. But they're still a great deal if you're looking to keep multiples stashed in various places so you don't have to go looking for them.
