Many of our customers look to us to help them with their flatness measurement projects. Sometimes they are looking to validate their substrate materials before they spend the money populating the substrates with their products and devices. Other times they are looking to validate the flatness or coplanarity of a finished part surface to see …
Laser Cut Hypotubes (LCHT) are used for many different medical procedures. Most LCHT features consist of small cut or drilled features that allow them to bend and navigate the human body. The inspection for the verification and validation of these small features is an important step in the LCHT’s manufacturing process. As the features shrink …

Digital microscopes typically take and record images using JPEG or TIFF file formats. If desired, image compression algorithms are then applied. Here are the main benefits. Image your whole surface while maintaining your resolution Using smart image compression techniques will allow you to zoom in on a large surface. The resolution will be maintained and …
Displays are constantly being developed with higher resolutions and larger screen sizes. The complexity of modern displays makes measuring the components a challenge. Intricate features of a display can be measured using microscopy, however microscopy techniques are often limited to smaller sample sizes. Peak Metrology offers larger positioning tables and stages to support large area microscopy which …
The VR microscope from Keyence has built in larger stage control and image stitching capabilities. This is useful for measuring larger parts that are greater than 200mm in any one XY dimension. There are a few important considerations to keep in mind when performing measurements over a larger area with this microscope. 1. There is …

Covering Keyence VK-X series scanning microscopes. Scanning microscopes can be difficult to optimize over large surface areas since their measurement depth of field is so small. If the surface you are trying to measure has a slight tilt to it, or if there are localized height differences across it, it will be hard to find …

Shadowing occurs when the laser is blocked by a part surface while trying to return to the sensor head. The problem: Missing surface data The triangulation principle, such as the one used by laser measurement devices, often has a limitation when it comes to measuring surfaces with tall features. These tall features obstruct the outgoing …

Small influences make a big impact on precision measurement processes When working with sub-micron and nanometer-sized features any external vibration influence on the equipment will negatively impact resultant measurement data. External vibrations such as nearby machinery, people’s foot traffic, steady-state floor vibration, and other sources have a large impact on how clean the measurement data …
Larger travel stages from Peak Metrology maintains measurement repeatability Often, larger travel stages are needed to expand the measurement volume of VR Optical Profilers from Keyence. These measurement heads have smaller, high-precision individual fields of view, but come with software capable of stitching these smaller areas together. Overlapping data regions are used to combine the …
