All corners are miter cut for a nice finish. Lens held securely in place with a wooden inlay. (NICE!) WARNING : I have included a Youtube video to demonstrate the power of this type of lens when placed in the sun. The lens should NEVER BE LEFT IN THE SUN UNATTENDED. Fresnel lenses concentrate several square feet of sunlight down to less than 1/2″. My personal tests have resulted in surface temperatures in excess of 2000 degrees farenheit WITH A SPOT LENS AND 900 degrees farenheit WITH A LINEAR LENS. VERY DANGEROUS. IF YOU DO USE THIS FOR SCIENTIFIC PURPOSES, DO NOT LEAVE OUTSIDE OR NEAR SUNLIGHT EVER. TREAT IT AND RESPECT IT AS A FURNACE OR BLOWTORCH. Stuff instantly can catch on fire. Buyer assumes all risks and agrees that separating the lens from the protective cover is done so at their own risk and responsibility. If you are crazy enough to use this for sun collection I strongly recomend wearing protective eye goggles (wielding/blow torch) to prevent eye damage. Protective clothing (fireproof) is also recomended as well as a large open space away from structures and autos. CHILDREN OR PETS SHOULD NEVER BE IN WORK AREA!
