About This Webinar
Beam profilers are critical tools for characterizing lasers and light sources, whether the goal is to gain fundamental knowledge during research and development, to set important design parameters during process design, or to diagnose problems in existing optical trains. Advanced laser processing methods such as photolithography, additive manufacturing, and surface processing often require tightly focused beams that are not limited to Gaussian beam shapes. While knife-edge and scanning slit techniques are two options for characterizing small beam waists, their inability to provide true 2D profiles makes them problematic for non-Gaussian beams, and therefore not suitable for some applications. On the other hand, traditional camera-based profilers generate full true 2D profiles, so they are a good choice for non-Gaussian beams. However, for small beam waists, cameras are limited by the pixel pitch of modern imaging sensors.

In this webinar, Logan Hatanaka of DataRay discusses camera-based options for capturing true 2D beam profiles of tightly focused beam waists by using magnification optics, like those included in DataRay’s Industrial Laser Monitoring System (ILMS). By carefully magnifying a beam waist onto a camera sensor, engineers can produce detailed profiles in true 2D, an excellent option for characterizing small beam waists, regardless of beam shape. The goal is to produce an optical system which does not affect the original beam profile; therefore, choosing appropriate optics for a magnification system is critical. Hatanaka addresses important lens parameters and shows how these parameters affect measured beam profiles using real-world data. With a properly designed magnification system, profiling small, complex beam waists is easy and repeatable.
