A light source, whether natural or man-made, typically emits a broad spectrum of wavelengths, including ultraviolet and infrared. In some applications, this full spectrum is acceptable or even desired. In others, however, it may be necessary to limit the wavelengths passing from the light source. This is where optical filters come in.

Every year, VisiMax Technologies holds a "Training Day" for all employees. Though the company's expert staff has thorough experience, the company recognizes the value of continued optical coating education.  Chris Murphy, VisiMax Vice President, explains why the company takes the time to devote 100% of a day to training on processes, equipment, and safety.
