Our custom made forensic safety glasses are designed to assist the user in viewing particular light wavelengths by blocking certain wavelengths while passing others. A common technique is to use a excitation light source of one frequency that causes the item to fluoresce at another frequency. By choosing a forensic safety glass that blocks the excitation light source while passing the fluorescence or emission, the user can view the item being studied.
Our forensic safety glasses are ANSI Z87.1 certified.
US – ANSI Z87.1
For protective eyewear meant for industrial or occupational use in the US, the governing document is ANSI Z87.1, and it has been in existence, through several iterations, for almost 40 years. OSHA in its regulations (see CFR 1910.133) specifically cites Z87.1 as the minimum performance requirement for protective eyewear, effectively giving it the weight of law. Where a hazard assessment in the workplace indicates that eye/face protection is needed, such protection must be provided, and it must comply with this ANSI standard.
The current edition of the standard is Z87.1-2010. In the standard, eye protectors are either non-impact or impact rated devices. Impact rated protectors must meet the established high mass and high velocity tests, and defined, continuous lateral coverage. The following “high” impact tests apply to lenses, as well as to the frames or product housing:
