3/11/2023 0 Comments Scanning slit profiler![]() In the case of a scanning slit, the beam should have a minimum of four times the slit width, providing a minimum of approximately 8 µm. If a camera is being used, the beam should be no less than 10 pixels wide to provide excellent accuracy. However with small beams, many things need to be considered. In the case of large beams, users require a profiler with an adequately large aperture. In comparison to pyroelectric and InGaAs varieties, Si and Ge sensors are less expensive. The laser’s wavelength establishes the kind of detector the beam profiler should possess. This article deals with questions that users need to ask to locate the right laser beam profiler for their laser and application.įigure 1. Currently, there are cameras and scanning slit profilers, which possess a number of options for different types of detectors. Sponsored by Ophir Photonics Group May 12 2016Īs there are several different types of laser (Figure 1), the need for many different profilers to oversee the range of lasers has increased.
