ABSTRACT:
Improved goggles for use with laser projection systems allow passage of a narrow band of red wavelengths that surround the wavelength at which the laser is projecting. The goggles block adjacent wavelengths. Thus, the laser image is in contrast, and is easily seen by a wearer. At the same time, the goggles pass at least a portion of the blue and green wavelengths. Thus, the wearer is provided with an image that is not unnatural, but includes most of the natural colors. In this way, the goggles not only provide a clear image of the laser beam, but also are easily worn by a wearer for an extended period of time.
