Blue light safety sensor

Blue light safety sensor

The PMA1121 analog blue light safety sensor provides an accurate, convenient, and cost-effective way to measure the harm of blue light radiation to the eyes in occupational settings. Employers, safety personnel, and risk management personnel can use this detector to protect workers from excessive blue light exposure every day. Such exposure, according to extensive medical research, can cause permanent and irreversible damage to the eyes, as well as visual field defects and visual impairments.

The PMA1121 analog blue light safety sensor can display the effective radiation weighting values of the American Conference on Government Industrial Health (ACGIH) spectral weighting function for blue light hazards. Light sources can produce blue light hazards, including monochromatic collimating lasers and parallel arcs, or tungsten lamps (such as search lamps). Flashes generally do not pose a serious danger because compared to continuous light sources, flashes have limited energy.

Typical blue light:

150 W halogen lamp at a distance of 50 cm -70uW/cm2

150 W xenon arc lamp at a distance of 50 cm -80uW/cm2
