µ m level small beam measurement

Scanning slit spot analyzer for measuring diameters less than 2; 0  U  The extreme small light spot of m has advantages that cannot be compared to other types of analysts Testing with the knowledge edge method can reflect the shape of the small light spot

0.1 µ m ultra high resolution

The scanning slide spot analyzer, based on a unique measurement principle, achieves a resolution of 0 for the spot&Nbsp; 1  µ m can more clearly and accurately reflect the morphology of the light spot without losing important features

Measurable high power beam

The scanning slit spot analyzer only allows light at the slit to pass through and collect power values at each time, and does not receive all the light power at once This allows the scanning slide spot analyzer to test next 100000 of high power laser

Innovative, precise, and compact structural design

The newly launched scanning slot spot analyzer by Dimension Labs has a rotating cylinder with a ± 90 ° adjustment range in the vertical laser incidence direction, so that the XY axis is marketed on the front responses to the long and short axes of a spot, outputting more accurate spot simulation and measurement

At the same time, an adjustable aperture is used structurally to cover the aperture of the light passing through, with a zero adjustable range of light passing through, effectively isolating the interface of environmental light and straight light, while protecting the aperture of the light passing through and frame slides, avoiding human touch and damage The adjustment method is also invasive and conservative.

Technical Introduction

The slit scanner includes a rotating wheel with two pairs of slits of different widths that are perpendicular to each other. There is a rotating motor installed in the rotating wheel, which can control the rotation of the rotating wheel and change the rotation rate. Laser is emitted from the entrance of the slit scanner, and while the rotating wheel rotates, it scans the x and y axes of the laser vertically through the slit. While scanning, the photodetector inside the rotating wheel records power and position information to obtain different time moments; X-axis and  The power magnitude at different positions and times on the y-axis. Process the data to obtain parameters of beam quality such as beam diameter, ellipticity, and center position

In the rotating roller orthogonal slit measurement scheme, the slit is used for physical attenuation, which can attenuate the measured light intensity without distortion to the linear response range of the detector. This measurement method can be used for high-power range laser beam quality measurement
