I really can’t disagree, I am particularly suseptible to UV as I had laser eye correction done this year and have to be extremely cautious at all times. I also work in the construction industry and eye safety is not ever something to skimp on.
This morning I ordered two pairs of these:
For a purchase like this I highly recommend going to a reliable source. I found options on Amazon, but not all of them were traceable back to consitent standards and testing.
Regarding the enclosure, here is a bit of info from Laser Safety Industries website:
Laser Windows | Laser Safety Window Options:
- For Class 4 lasers, please refer to the acrylic laser safety windows and the glass laser safety windows.
- For only our low power laser safety windows, or what seems to commonly be referred to by our clients as “laser shielding” or “laser shield acrylic sheets”, please refer to our low power laser safety windows. Please note, these should never be used with class 4 lasers, please consult your Laser Safety Officer or please feel free to give us a call.
A single 24in x 36in window rated at OD5 is over $700. Low power windows, not acceptable for class 4 lasers, are OD3 but cost $260. Our conclusion is that based on the price we paid there is no way the enclosure provides enough safety for our eyes.
