What is the difference between 200W and 300W rated laser protection products?
The difference between 200W and 300W rated products is the addition of an extra layer of material, providing higher maximum irradiance protection:
- Maximum Irradiance: All of our products are tested to withstand 200W/cm² or 300W/cm² with a beam size of 5mm for up to 100 seconds. These tests simulate a direct hit under controlled conditions.
A common misconception is that a 1500W laser requires a 1500W-rated barrier or curtain solution. This is often not the case (though every situation is unique). In practice, all of our laser safety barriers, curtains, eyewear, and windows are specifically designed to contain diffused laser energy, not direct laser contact.
To clarify this distinction, we have provided an image demonstrating the difference between direct hit and diffused radiation control. In practice, all of our barriers and curtains are designed to contain scattered or diffused laser radiation, although we test them to withstand a direct hit for up to 100 seconds. Proper engineering and administrative controls are also essential components of a comprehensive laser safety strategy. For more guidance on laser safety, refer to our Class 4 Laser Safety Guide.
