Description

Laser Safety Window 930-1090nm & 9000-11000nm is a precision optical shield designed to provide comprehensive protection in environments using near-infrared and far-infrared laser systems. This safety window enables operators to view laser processes from outside the Nominal Hazard Zone (NHZ) without risking exposure to hazardous wavelengths. Whether used in system enclosures, doors, panels, or room windows, the window’s balanced combination of optical density and visible light transmission ensures both safety and visibility.

LaserStar offers this safety window as part of its broader range of laser protection accessories, specifying filter performance, material properties, and design flexibility. LaserStar Technologies

Protection & Filter Specifications

The Laser Safety Window 930-1090nm & 9000-11000nm is engineered with multiple optical density (OD) levels across different wavelength segments:

• 930 – 1030 nm: OD 5+

• 1030 – 1090 nm: OD 7+

• 9000 – 11000 nm: OD 6+

• For CE compliance, it supports DI AB5 for 930–1030 nm, DI AB6 + IR AB7 for 1030–1090 nm, and DI AB4 for 9000–11000 nm LaserStar Technologies

This structure ensures strong attenuation of hazardous laser emissions while allowing safe viewing. The window also meets European safety standards (CE) for laser protection. LaserStar Technologies

Optical & Physical Properties

• Visual Light Transmission (VLT): 20% — balancing protection and visibility LaserStar Technologies

• Standard Size: 1000 mm × 1200 mm (39.4″ × 47.25″) LaserStar Technologies

• Material: 5 mm polycarbonate (PC) — strong, durable, heat resistant, and transparent LaserStar Technologies

• Color: Green tint to enhance contrast and filter out unwanted spectral components LaserStar Technologies

• Custom Sizes: Available on request (minimum quantity applies) LaserStar Technologies

The use of polycarbonate offers benefits in durability and impact resistance compared to acrylic or glass — important in environments where safety, handling, or accidental impact may occur.

Applications & Use Cases

The Laser Safety Window 930-1090nm & 9000-11000nm is well-suited for a wide range of laser system environments, including:

• Nd:YAG / Fiber Laser Enclosures: Protection for 1064 nm systems operating in the near-IR band

• CO₂ / Far-Infrared Systems: Covering the 9–11 μm band for CO₂ laser protection

• Laser Welding & Marking Stations: Safe viewing windows on workstation doors or partitions

• Laser Cutting & Engraving Enclosures: Visual access panels in laser machine housings

• Optics & Research Lab Windows: Barrier windows in lab setups needing simultaneous visibility and hazard protection

In each of these contexts, the window allows operators to monitor laser processes while ensuring compliance with safety standards for near-IR and IR laser exposure.
