Resolution in width direction: 0.05 mm.
International standard ISO 11146-1:2005 specifies methods for measuring beam widths (diameters), divergence angles and beam propagation ratios of laser beams (if the beam is stigmatic) and for general astigmatic beams ISO 11146-2 is applicable. The D4σ beam width is the ISO standard definition and the measurement of the M² beam quality parameter requires the measurement of the D4σ widths. Webb30 jan. 2024 · Laser line sensors feature a maximum line width of up to 64 mm, depending on the measuring range. The sensor can be positioned so that the dimple peaks and the basic thickness of the sheet can be determined reliably by the laser line.

For the pixel pitch (or, equivalently, pixel size), we recommend that the smallest beam you will measure should fit within at least 10 pixels. For example, if the sensor has a pixel pitch of 5.5 µm, you should not try to measure beams smaller than 55 µm with it. govt first grade college hunsurWebb12 juni 2024 · 7 illustrates the result of an experimental setup measuring depth of semi-transparent media with sub-pulse width resolution.
