Now hundreds and thousands of dollars a shot at every turn, does not easily acceptable to consumers. The recent good news on an Australian University, saying that he could have developed a new lens which costs are extremely low, and the main ingredients of this lens, it is silicone!
We have written about earlier drops made from microscope, and of course these lenses are made of a similar principle, but can be fixed by silicone instead of water droplets focus features.
Silicone is actually solid polydimethyl siloxanes (PDMS), it is colorless, odorless, non-toxic, non-flammable, highly hydrophobic and elastic that is well suited to produce has become shaped glasses with breast fillers. Its high degree of transparency and plasticity, makes PDMS become good material for production of this low cost eyeglasses.
Production method is probably the PDMS bit of liquid on a flat surface, inversion plane PDMS accumulation in the Central Government, and then to put the 70 degree Celsius oven for at least 15 minutes of baking and roasting (I have not explain as much as possible like in the whole cake) and PDMS is heated to crystallize. If we want to increase the curvature of the lens, then repeat the entire process again in the PDMS, until reach the desired curvature.
So what about this lens optical effects?
There is no disappointment or surprise? Microstructure effect of this lens is excellent, and developers hope that this lens can be used in scientific research or educational purposes. But given its small size and optical performance, believed to be a conventional lens material also takes a very long time.
But come to think of a layer of photographic products are high prices and high profits and short cycle, so that companies want to develop. Instead of this low cost, of the corresponding low profits glass may be the major vendor support? Haha.
