Couldn't be, that was zinc that was melted as you can see. If it was a 1909 S VDB it would be mostly copper and those were mostly zinc so they were later that 1982.

 

haha i feel dumb

 

Would a laser this strong even be legal to own?

 

Like 09 S VDB's are rare

 

It is a fresnel lens, not a laser. It uses the sun and concentrates the focal point. I bought 5 of them from the Salvation army from old overhead projectors. Haven't decided what to make yet, I was hoping to make a solar top for my ceramics kiln.

Some projection TV systems used Fresnel lenses up to four or five feet across. Most of those videos seem to be using ones of two feet or less and they are getting temperatures of over 800 degrees. A four foot lens gathers and focuses four times as much light.

 

Aw heck Jim. Put on the "mad scientist" lab coat and be creative........

 

So instead of burning just 1 ant at time, you can cook the whole mound!!

 

Everything is legal until you get caught.
