When asking someone for a laser beam profiling demonstration, it is important to understand what you are asking for and what you should expect. This white paper covers the steps needed to take to set up a demonstration, and what is expected of each party.
This article presents the advantages of using lock-in amplifiers for measuring signals below the noise floor, how they work, and available devices from Ophir.
This white paper discusses sensor fusion, a process that merges data from numerous sensors to create a more complete understanding of the laser-enabled process.
The lower operating costs of LED luminaires drive growing demand for them in consumer and commercial markets. This increased demand requires an adaptation to improved quality testing methods that can provide superior measurements and not slow down the process of production.
This application note presents how Ophir Optics’ BeamCheck system is able to measure critical laser beam parameters for laser-based additive manufacturing.
This article reports the measurement results acquired when a metal sheet was scanned with a resolution chart engraved on its surface.
Traditionally, laser operators only verify a laser’s average power or energy to improve efficiency and, if everything is in order, put their laser back into service. This article discusses steps required to identify and use a camera profiling system (arrayed camera, attenuator, and beam dump) for laser management.
A critical component in a laser manufacturing process is the understanding of which process parameters or key control characteristics must be measured and how they will relate to product quality and waste. A laser profiling system can be a great benefit for characterizing and identifying which variables affect product quality and waste minimization. Unfortunately, many companies realize this too late and incur more expenses and extended downtime than necessary when trying to implement the system near the end of the process. This article dives into a method of using in-house tools, like laser profiling, to characterize and optimize a process in advance so that product quality and process variability may be understood and maintained.
Many of today’s conventional marking, welding, drilling, and cutting laser systems have the challenge of focusing the laser accurately on the object’s surface. As the demand for faster and more precise manufacturing processes increase, the need to control the focal point of a laser becomes much more critical. This application note discusses a new laser measurement method that integrates Optimet sensors into laser systems, offering the benefits of autofocus capabilities while upgrading a number of system performances.
In order to improve laser-based processes, a variety of parameters must be measured to understand how design changes effect performance, and how to help avoid component degradation. The challenge occurs when figuring the proper frequency of measurements throughout the life of the laser, choosing which measurements should be tracked, and what should be done with the collected data. There are five times within a laser system’s lifetime where the collection and application of laser performance measurement data are critical to the process’ outcome.
