Max Power (Saturation) of CCD Beam Profilers
CCD cameras are used very often as UV, visible, and near-infrared laser beam profilers. When selecting a beam profiler, you always need to check the laser parameters against the beam profiler...
View ArticleMeasuring LED Fixtures & Luminaires: Without an Integrating Sphere
Need to measure flux, color, and flicker of your LED lamps and luminaires? FluxGage is a completely new method to measure all these features of your LED, without using an integrating sphere. This will...

Using a Silicon Beam Profiler for UV Lasers?
Read this before you do any damage. Technically, silicon absorbs well down to 350 nm, and could even work at lower wavelengths (to 190 nm). However, silicon is especially susceptible to damage from UV...

How to Calculate Laser Beam Size
Gaussian laser beams don’t have a simple cut-and-dry beam width. If you’re not familiar with the math behind a “Gaussian” you might wonder why this would be. Here’s why: The image above (from...
View ArticleBeamSquared for Easy M2 Measurement
This new video is a nice, short primer on Ophir-Spiricon’s new “BeamSquared,” replacing the M2-200s as the M-Squared measurement system of choice: Find out more here:...

Integrating Spheres for Lighting and Laser Diode Measurement
An integrating sphere is a powerful tool to capture all the light of a widely divergent beam. The inside of the sphere is coated to be highly-reflective, in a diffuse manner. This scatters the light...

Recalibrating Your Laser Power Meter for Long-Term Accuracy and Reliability
We’d all like to imagine that our things will stay in mint condition forever. But we know that’s not the case. Just like laser degrade (and therefore must be measured), the measurement equipment...

Measuring Really Small Laser Beams (< 10 microns)
Profiling small laser beams and measuring the beam size (or mode field diameter) can be a serious challenge. But it’s critical to measure, especially in such applications as fiber optic coupling...

Laser Beam Optics Calculators
A laser is a complicated animal. Whether you’re a lab researcher or an industrial worker, there are several parameters you might need to calculate, such as power density or ideal focus spot size. We’ve...
View ArticleAdditive Manufacturing: Maintaining Quality & Control
Additive manufacturing (AM) has exploded in the last few years. No longer just a tool for quick plastic prototypes, AM now works with metal and can be used to create specialized parts that cannot be...
