Of course, the best way to know the amplitude of the movement is to count the fringes of a known radiation (usually given by HeNe laser) Share. This stability makes it excellent for use in OEM applications. Even though the eye is less sensitive to this wavelength than others (notably visible light), continuous exposure to a focused beam will cause damage. Firgure 1. The measurement technique was demonstrated for transient n-dodecane liquid lms in the absence and presence of n-decane vapor. Kai Ou, . Lasers emitting in this wavelength region are particularly hazardous for the eye, as near-infrared light is transmitted and focused to the sensitive retina in the same way as visible light, while not triggering the protective blink reflex. Extensive exposure to near infrared (IR-A) radiation may also contribute to such cataracts. As nouns the difference between laser and infrared. 850nm torches will give the best picture, they will have a slightly longer usable range and they are less likely to create blurry images than 940nm torches. Far Infrared (1400 nm - 1 mm) Most of the radiation is transmitted to the cornea. The infrared heads for < 10 W power and for 10 to 50 W power are coolerless because our technology allows for extremely efficient heat dissipation.
