NOT ALL FRESNEL LENSES ARE CREATED EQUALLY. ALL THE LENSES WE SELL WERE SPECIALLY SELECTED FOR THEIR SUN COLLECTING ABILITIES. ALL HAVE BEEN TESTED AND THEY ARE THE BEST OF THE BEST FOR SOLAR NEEDS. FULLY RESTORED LENS IN WORKING CONDITION - JUST ADD A FRAME HERE IS THE PROCESS: Lens with crack or chip that goes all the way through. Restored See next photo. ------------------------------------------------------------------------------------------------------------- Area is spot heated to melt plastic, resin is added and deprived of oxygen and a UV cure drop is mixed in. The area is polished and the restored area or areas are stronger than the original lens. This will not crack or run. ------------------------------------------------------------------------------------------------------------- This is a larger crack that is in the process of running or getting bigger. Next photo shows the restoration. ------------------------------------------------------------------------------------------------------------- The same process listed above is applied but an ultra-highspeed device is also used to permanently stop the crack. This will NOT re-crack or run. Again, these restored areas are stronger than the rest of the lens. Frequently Asked Questions: Q: Does the scratches or restoration areas reduce solar performance. A: Less than one percent. The area of minor scratches and restorations do block a bit of sunlight but they are much less than one percent of the total area. Q: Will the restored crack reopen or run when used or handled. A: NO, the restored area is stronger than the rest of the lens and this process has been perfected over a 3 year period. It is UV resistant, resistant to temperature extremes and is not affected by cleaning, washing, or weather (humidity or rain). It is solid. Q: Why are you selling these now? A: These lenses have been stored in a controlled environment for a few years. We have perfected the process of restoration and they are ready to go. Spot Fresnel Lenses are becoming very, very rare. This gives the backyard scientist on a budget a great lens at a great price. I actually use scratch and ding lenses in most of our Youtube videos. Long lasting and powerful! Q: Do these lenses have the same buyer protection and money back guarantee as your other lenses? A: YES, ALL GREENPOWERSCIENCE products are backed with a full 14 day customer satisfaction that currently has our rating at 100%. Please check our feedback! Any other questions, please feel free to ask. We would not sell these if they did not work and were not 100% tested for solar usage. WARNING!!!!!
