WebbTraditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale sign of amp glow. As the ASI2600MM Duo uses zero-amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging. QE (Quantum efficiency) In most circumstances, visible light is not hazardous, and measurement of continuous visible light emissions is usually not necessary. When exposed suddenly to a highly intense visible light source, most people exhibit an aversion response that includes blinking and turning the head. This response typically occurs within … Visa mer The threshold limit values (TLVs) refer to values for incoherent (non-laser) visible and infrared radiation in the wavelength region of 305–3,000 nm that nearly all workers may be exposed to without adverse health … Visa mer To evaluate the hazard, the exposure to the eye and skin at the location of exposure is compared with the respective exposure TLV. … Visa mer American Conference of Governmental Industrial Hygienists (ACGIH), 2016.American Conference of Governmental Industrial Hygienists TLVs and BEIs – 2016, … Visa mer If light hazards have been identified in the work place, it may be necessary to implement one or more control measures to eliminate exposure or reduce it to as far as is reasonably … Visa mer
