ALL HAVE BEEN TESTED AND THEY ARE THE BEST OF THE BEST FOR SOLAR NEEDS.AS WE LEARNED YEARS AGO, NOT ALL FRESNEL LENSES WILL WORK WELL. ______________________________________________________SIMILAR LENS IN ACTIONSECURED IN A WORKING FRAMEALMOST 4 FEET TALL!!!!!!!!!!!47 inches TALL by 36 inches WIDE Lens LENS IN GOOD GONDITION WITH A FEW MINOR SCRHATCESbut that WILL NOT affect performance if using for sun collection. OVER ALL EXCELLENT CONDITION THIS IS A LINEAR BEAM FRESNEL LENS.This type of lens is desirable for heating liquid as it produces a flat beam that is 6 inches long vs. a small 1/4 inch spot.This lens will melt zinc (692 degrees Farenheit) anywhere along the 6 inch beam but will not melt glass. This is perfect for water boiling applications and it is less likely to destroy your equipment.THIS IS NOT A TOY AND THE WINNINGBIDDER AGREES TO THE WARNING AND TERMS BELOW.All corners are miter cut for a nice finish.Lens held securely in place with a wooden inlay. (NICE!)Special insert insures you lens will not fall out when in use. Lens stays flat even when horizontal. NO DISTORTION!!!53 POUNDS OF PRESSURE JUST RIGHT TO HOLD FORTHE LIFE OF THE LENS.PRE-DRILLED HOLEWARNING : 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!
