Starrett introduces HDV250 featuring superior surface illumination and high-resolution imaging for greater accuracy.

Inspecting with Optical Comparators provides an overview of the optical comparator, which uses optics to project an enlarged, two-dimensional shadow of a part onto a glass screen for measurement of ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Optical Gaging Products (OGP®), a world-leading manufacturer of precision multisensor metrology systems for industrial quality control, announces a technological breakthrough in value-class video ...

Hackers frequently find themselves reverse-engineering or interfacing to existing hardware and devices, and when that interface needs to be a physical one, it really pays to be able to take accurate ...

Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

Simple optics display the part upside down and backwards on the glass screen. Corrected optics display the part right side up and backwards. Fully corrected optics yield an image identical to the part ...
