Optical light filters, useful for eye protection from laser radiation, are provided. The filter can absorb harmful radiation from lasers of several (at least six (6)) types which have a range of different specific wavelengths, yet permit sufficient visibility. A novel mixture of compatible absorbers in a transparent plastic carrier, having the required stability to withstand processing conditions and having satisfactory stability for use under environmental conditions is disclosed.
本产品提供了用于保护眼睛免受激光辐射伤害的光学滤光器。这种滤光器可以吸收多种(至少六(6)种)具有不同特定波长的激光发出的有害辐射,但仍有足够的可见度。本发明公开了透明塑料载体中兼容吸收剂的新型混合物,这种混合物具有所需的稳定性,能够承受加工条件,并在环境条件下具有令人满意的稳定性。
