Laser observation window products are available for most common (e.g., Nd:YAG, CO2, Argon, etc.) laser wavelengths; however, the level of protection will vary depending upon the window material and laser wavelength being attenuated. Acrylic sheets (2'x 3' x 1/8" & 3' x 4' x 1/8" standard sheets) are more rigid than PVC film and can be cut to custom sizes. PVC film comes in two standard widths of 15" and 30". Virtually any length of film is available. Warning signs and labels are available for almost any laser application. They are manufactured in four configurations: PVC, plastic, magnetic & paper.
