Selecting Industrial Laser Optics
Lasers are one of the most significant and prevalent inventions of the 20th century. They have created entire industries, optimized many processes and enabled thousands of applications ranging from CD players to nuclear fusion research. It is because of the laser that we have sophisticated flying vehicles and infinitesimally small microprocessors. Lasers have enabled eye surgeons to restore better than 20/20 vision to the weak-sighted, and have served as crucial tools in the field of internal
