Keeping the Optical Spherical Lens clean often increases the life of the optical glass lens. Because the pollution causes many problems in the lens, the uneven distribution of the laser power during reflection makes the lens base temperature high and the marginal temperature low, and this change is optically called the lens effect.
Failure to comply with the requirements and attention to lens finishing, random handling will create new pollution or even scratch the optical glass lens, resulting in unnecessary losses. In general, you should pay attention not to let the mirror touch the hard object directly. When cleaning, it is best to clean it with water (or a small amount of detergent), then use a special test cloth or excellent cotton paper to dry the water droplets on the lens. If the Optical Lens is not scratched, it can't be used all the time.
