When is Smooth Too Rough?
When you think of roughness, you might envision a wide assortment of sandpaper grits, whereas the abrasive material size decreases, the grit number increases. Coarse 60 grit sandpaper is almost pebble-like. Medium sandpaper-like that is used on wood is 120 or 150 grit. A super smooth 3200 grit wet and dry sandpaper is so fine it could practically pass for paper. As you probably already know, ...

Accuracy and Uncertainty... they are not the same
How tall are you? In everyday conversation you probably would answer in a general way by saying, “I’m five foot, eight inches tall.” But how true is your answer? Are you exactly 5’8” tall? It’s likely you rounded up your height to the nearest inch, so in reality our height is probably somewhere between 5’7”and 5’8”. If we want a ...

Why Graphics Really Matter in Metrology Software
It’s a saying we’ve heard more times than we can count. “A picture is worth a 1,000 words.” We know its meaning—a picture, or graphic, tells the story quickly, enabling us to organize our thoughts and interpret meaning more easily than the same material presented in words or numbers. Studies on learning styles repeatedly suggest that presenting data using visual ...

Additive Manufacturing — New Frontiers for Production and Validation
Today, additive manufacturing (AM) is dramatically changing the way that manufacturers produce end-use parts and components. Not surprisingly, analysis of the accuracy and repeatable tolerance range of AM has become a critical issue. If an AM part is integral to a safety–critical aerospace or medical application, it is essential to achieve dimensional and surface finish tolerance targets ...

What is an Aspheric Lens?
Aspheric lenses (or more simply, aspheres) are used in a wide variety of applications as a way to optimize optical performance while ensuring an efficient design. They are characterized by a radius of curvature that varies from the center to the edge of the lens, affording them greater optical functionality. Because of this, they can reduce the number of elements needed in an optical assembly ...

How Smooth is Smooth?
This question is of interest to many manufacturers today. Why? Because more of them are making high precision, small-scale components that are critical to the function of a host of end products. A company’s livelihood may mandate that the components they use in their products are uniform, definable, and "high-precision". This is where an understanding of smoothness is helpful. So how smooth ...

The Promise of Hydrogen: Metrology of Fuel Cell Manufacturing
Hydrogen is one of the most abundant elements available on the planet. It is increasingly recognized in the transportation industry as a critical source for fuel cells. Fuel cells convert the chemical energy of a fuel directly into usable energy – electricity and heat – without combustion. They have recently penetrated the electric vehicle market due to their efficiency, quick ...

3D Optical Metrology – Versatile Tools for Advanced Manufacturing
When looking at metrology, general discussion often revolves around the relative merits of contact or non-contact measurement solutions. There is now a drive across nearly all industries for smaller and more complex components (which are often prone to contamination or damage by even the slightest contact with a probe). For these exacting applications, non-contact optical metrology solutions, or ...

How Metrology Can Improve Electric Vehicle Gears Processing
Automotive manufacturers recognize that consumers are quickly shifting their views towards greener transportation. This is driving newer or improved manufacturing processes to produce electric vehicles (EVs). As interest ramps up in creating efficient EVs, the decline of the internal combustion (IC) engine is inevitable. As the IC engine is phased out, the number of necessary drive train ...

Excitation Correction in a Fluorescence Spectrometer
When fluorescence spectra are measured in Edinburgh Instruments fluorescence spectrometers, two types of correction can be applied to the spectra; excitation and emission. In our previous blog post, we focused on emission correction and its role in the detection system. Now we turn our attention to excitation correction.Fluorescence spectrometers use xenon arc lamps as the excitation source for ...

Comparing Optical Turbidity With LISST-ABS
For measuring suspended sediments, the use of optical backscatter sensors or other turdibity sensors is widespread. At the same time, it is understood that these sensors respond to total particle area, not volume or mass. In other words, optical turbidity sensors have this property: their sensitivity decreases with increasing grain size. The decrease follows 1/diameter. This has been published ...
