Details on all of our laser measurement instruments.

A laser beam profiler will increase your chance of success anytime you wish to design or apply a laser or when you find your laser system is no longer meeting specifications. You would ...

Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. However, there are enormous challenges that must be overcome ...

Researchers are devising ways of generating and using more complex higher-order multimode formats, such as a TEM03 or TEM33. Some current examples are: telecommunications, analytical ...

BeamWatch AM has been designed specifically for use in the additive manufacturing industry to provide non-interfering real-time beam measurement at the location of the working plan ...

Ophir Photonics uses pyroelectric detectors in a number of their products, both for beam profiling and for laser power measurement.

There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this applications note is to explain some of the terminology used in the ...

The m² Beam propagation measurement is made by observing how a laser beam behaves when focused with a lens. The ISO 11142 protocol calls for measurements to be made along the z-axis ...

Having worked in laser marking and engraving for several years, I can say that there is a certain mindset when it comes to laser quality that, in some cases, could be a dangerous one, ...

AM involves building up a structure by adding material to it layer by layer, with each layer being a precise cross section of the structure. Originally used for rapid prototyping, AM ...

The underlying operational principle is based on the fact that residues of body fluids, natural oils and sweat absorb radiation in the infrared range.

Many non-invasive methods for measuring blood glucose have failed because they were not accurate enough: Glucose values in body fluids such as tears, saliva or sweat do not correlate ...

With lasers there will always be opportunities for improvement. Reliable technology for measuring the laser beam can really help with process optimization.

Beyond knowing power or energy, most laser owners and operators have never seen their beam in real time, because most lasers are invisible to the human eye. Users rely on the certification ...

The technology used in the BeamWatch laser beam profilers enables the measurement of high-power beams without ever touching the laser beam. As the technology is relatively new, it has ...

Setup and location of the beam was relatively simple. The X and Y movements were used in conjunction with the 633 nm target laser to center the beam on the camera chip.

Dynamic range is meant to characterize the ratio between the highest and lowest measurable signals (i.e. the signal range). As we've written before on our blog, most laser beam profiling ...

Successful outcomes require the power density distribution of the laser beam, as it is delivered to the work, to be symmetrical, uniform, and stable.

There are a number of valuable tools found on the Ophir web site that help lasers users determine the appropriate sensors for their laser beams. These tools also help compute power ...

To create consistent, strong structures using laser-based additive manufacturing processes that meet flyable DOD standards or FDA requirements, the metallurgy must be consistent. In ...
