laservision plastic laser protection windows

The technological development in the field of absorbing dyes during the last years results in more and more resistant plastic laser protection windows. In the past the plastic windows were commonly used against stray radiation. Meanwhile some plastic laser protection windows achieve a laser resistances comparable to that of mineral glass windows. A representative example therefor is the laser protection window P1P10 with 6mm thickness. Between 1030nm-1400nm it achieves with OD8+ and a 10 seconds test time an EN 207 protection level of D LB7 + IRM LB8. laservision offers a large variety of plastic laser protection windows for different laser applications.

An essential advantage regarding plastic laser protection windows is the availability of much larger sheets (up to 2mx3m) and the lower weight. The main application range is machine building and laser enclosures. For such applications laservision is offering a large variety of different plastic laser protection windows depending on the wavelength and application.

Windows are not considered to be PPE and can be marked with their optical density OD only, but as a standard, most materials do have a certification acc. to EN207 and acc. DIN EN 60825-4 and indicate LB ratings. A test acc. EN12254 with AB-protection levels is defined up to a power of 100W or 30J only. Laser enclosures or housings (as a part of the laser mechanism) are not a part of the application range of the EN12254.

Highlights

• Low weight, good optical properties
• Available for many laser and laser combinations
• Most window filter certified acc. EN207 with 5s and 10s
• Dimensions up to 3000mm x 2000mm for certain materials
• Some filters available in 3mm or 6mm thickness
