Laser Safety Window| Laser Safe Glass
At Excelite, our infrared laser polycarbonate sheet is designed to safeguard the Face Shields for flame welding and cutting or equipment operators.
The high temperatures associated with flame welding and cutting emit a spectrum of visible, ultraviolet, and infrared light that can pose a risk to your eyes when the brightness exceeds safe levels.
Excelite Laser safety window(also names IR polycarbonate sheet, laser safety glasses) crafted from high-impact polycarbonate sheets, our laser safety products are designed to withstand high-power laser beams, offering unparalleled protection against a diverse range of laser types, like 1064nm Nd:YAG, but not CO2 lasers(10.6um wavelength).
With an Optical Density (OD) that exceeds 6, these windows block UV and IR light providing protection during gas flame
welding and cutting operations as a barrier against harmful laser radiation.
But we understand that laser protection isn’t the sole requirement. Our laser safety glasses also deliver on performance, boasting exceptional Visible Light Transmittance (VLT) for crystal-clear visibility. This feature is crucial for operators who need to maintain precision in high-stakes environments, whether that’s in aerospace, healthcare, or advanced manufacturing sectors. Available in acrylic and custom sizes, Excelite’s laser safety viewing windows aren’t just a safety precaution; they’re an essential tool for maintaining both operational efficiency and stringent safety standards.

1.Laser safety cover for equipment machine
Laser protective polycarbonate sheets can be used to create enclosures and covers for laser cutting and engraving machines, protecting workers and the surrounding environment from laser radiation.
2.polycarbonate laser guarding screen for Medical lasers
Laser protective polycarbonate sheets can be used to create shields or barriers that protect healthcare workers and patients from laser radiation during medical procedures.
3.Polycarbonate laser protective sheet Manufacturing
Laser protective polycarbonate sheets can be used to shield equipment and workers from laser radiation in manufacturing facilities, such as in the automotive or aerospace industry.
These polycarbonate sheets include a colored tint that enhances protection against specific types of laser radiation.
Laser enclosures, laser safety window are specifically designed to isolate various types of laser activities, including those involving excimer, argon, alexandrite, IPL, IR lasers, and KTP.
Lightweight and durable Laser Welding Helmet offers superior protection. Common Laser Applications Nd:YAG – 1064nm, Alexandrite – 755nm, General Region of Laser Protection: Infrared (IR).
Laser welding viewing windows, Fiber Welding Windows, enable safe viewing access from the perimeter of your laser welding safety zone, protecting observers from hazardous radiation while maintaining clear visibility.
Suitable for various wavelength lasers’ processing equipment, laser marking system cover plates, laser management area partitions, mobile protective screens, etc.
Class 3 and Class 4 lasers’ direct and diffuse reflections are harmful, so corresponding laser protection windows must be installed. The GB7247 standard also mandates laser protection baffles for these classes. Installing protective windows on Class 2 laser processing equipment can further enhance operator safety.
Not necessarily. Common thicknesses are 5mm and 3mm, with similar parameters. Different thicknesses and sizes result from varying device window design requirements. Stacking two 3mm thick laser protection windows with the same parameters will increase the protection factor, but thickness alone does not determine protection parameters.
The choice of base material for laser protective windows significantly influences the protective performance of the finished window. You can contact us to find the difference with two material.
Under normal circumstances, if the equipment has been equipped with a laser protective window with appropriate parameters, the operator does not need to wear laser protective glasses. However, if discomfort occurs, it may be due to unsuitable parameters or light leaks in the equipment, and wearing laser safety glasses is still recommended. Wearing glasses is necessary when performing laser calibration and debugging in the equipment.
Absorption protection is all-round protection, absorbing and protecting light of corresponding wavelengths. It has no selectivity to the light source and can protect various diffuse reflection lights. Even if there are scratches, it will not affect the protective effect. Reflective protection, on the other hand, is selective to the light source and must face the protective surface for greater effect. Its practicality in an actual factory environment is limited.
No, most laser protective windows are made of organic materials and cannot be cleaned with high-concentration organic compounds like alcohol, acetone, or dichloroethane. If fingerprints or marks are present, use alcohol liquid below 2% or soapy water, and dry with a glasses cloth. Normal towels are not recommended as they may leave marks.
