Laser Safety Window P1P21 in polycarbonate 3.1 mm gold

Three standards on the same pane: P1P21 is certified per EN 207, EN 12254 and EN 60825-4. The gold-colored filter is made of polycarbonate with a scratch-resistant coating and weighs little for its protective range; the thickness stays around 3 mm.

The protection covers both ends of the spectrum and the broad field in between. In UV and blue, the filter holds optical density OD 10+ from 180 to 458 nm. In the near infrared, OD 5+ spans the whole 815 to 1100 nm, sharpened to OD 8+ between 880 and 1075 nm and OD 10+ between 940 and 1055 nm. In the infrared, OD 8+ applies from 5230 to 14570 nm. The higher the OD number, the less laser light gets through; the full table is under Technical data.

That breadth makes P1P21 a window for mixed laser fleets: high power diodes, disk, Nd:YAG, fiber and CO2 lasers behind one and the same pane. With approximately 50 percent daylight transmission and good color vision it works in daily operation, for small and large beam diameters alike.

The window comes in four standard sizes and can be made to measure up to 2000x1150 mm. Unsure whether the protection levels are sufficient for your laser? Get in touch with us.
