RESUMO
The transitional near-infrared (NIR) laser was defined as ranging from 1.3μm to 1.4μm, within which the most sensitive tissue to laser damage changed from the retina to the cornea.The ocular damage effect has attracted much attention due to the increased varieties and output power of laser in this spectrum region in recent years.Compared with visible and mid-and-far infrared wavelengths, the ocular damage effect induced by transitional NIR wavelengths has many peculiarities and impact factors due to the bulk absorptionby ocular media.This paper reviews the existing ocular damage threshold data and analyzes the characteristics, impact factors and unresolved issues relating to ocular effects induced by laser radiation over the transition zone.
RESUMO
The assurance mode from laser source for medicine is brought forward based on the three-tier mode of the whole assurance system in equipment of scientific research that is in the measurement of quality control personnel, engineering technique personnel and operator. The successful implementation of model will do laboratory equipment for the conditions of security work to a new level in our academy that can play important protection effect in overall research tasks.
