When precision and image quality are critical to the performance of an optical assembly, minimizing the number of lenses can become a critical design consideration.
The world’s first laser came into the world on May 16, 1960, a little over 50 years ago. Invented by Theodore Maiman, a PhD experimental physicist, it changed the world as we know it. Because of it, millions of blind people are now able to see and machine tools are able to precisely drill holes ranging from a few microns to several millimeters in diameter in the hardest of metals.
When the laser was first invented over 50 years ago, hardly anyone envisioned its use in eye surgery. Today, however, the laser has become an indispensable tool for many eye surgeons and has largely replaced the traditional scalpel in many procedures. High Power Laser Pointer are widely used, for example, to counteract the effects of diabetes, to reshape the cornea of the eye to improve sight and to remove cataracts that can impair vision.
