Scanning slit profiler9/17/2023 Carbon dioxide (CO 2) lasers are widely used in materials processing, and have a 10.6 micron wavelength that cannot be profiled with most cameras. Slit scanners can typically measure down to 4 microns without the use of magnifying lenses.īecause slit scanners measure beams at high powers with little or no attenuation, they are ideal to profile beams used in material processing. They also prohibit analysis of a beam at its focus because the attenuator increases the optical path length of the beam and may add aberrations. Attenuation optics can distort a laser's beam and add additional complexity into the measurement. In many applications scanning slits eliminate the need for additional optics, such as lenses and attenuators. While different techniques and instruments are available for profiling laser beams, this versatile design uses scanning slits to accommodate a wider variety of wavelengths, beam powers, and beam sizes. Optical assemblies are used in an extensive range of technical applications to deliver a laser beam of a certain size, quality, and intensity to a region of space.
