Surface Finish Analysis

Surface Finish Analysis Banner

 

Q-PLUS offers advanced surface finish analysis and surface mapping and metrology capabilities 
including graphical depictions, numerous sensor configurations, many algorithm and post-processing options, and even the raw surface finish data. All surface finish measurements comply with ASME-B46.1.

How we acquire surface finish data:

  • Skidded 2D Contact Profilometry
    This type of measurement process involves a gage with a sensitive stylus contained within a probe attached to the metal rest pad, or skid that rests on the object being analyzed. The stylus and skid move together to measure the average roughness of the part's surface.

  • Skidless 2D & 3D Contact Profilometry
    Skidless surface finish analysis is a contact measurement method of acquiring finish data with a stylus. Because the skidless gages use an internal precision reference surface, these gages can measure form and waviness in addition to roughness on a micro-inch level.

  • Noncontact 2D & 3D Optical Profilometry
    This profilometry is a non-contact method which accommodates many sample geometries via chromatic confocal technology which uses white light to collect measurement data. However, whereas interferometry uses the superposition of waves after they are reflected off the object, chromatic confocal sensors measure the wavelength as it hits the surface of the object.

  • Nano Scanning

    Nano Scanning involves 3D scanning at the sub-micron level and is accomplished with a chromatic confocal sensor. This type of scanning can be used to measure or digitize very small geometry and can also acquire surface roughness data.

Q-PLUS Labs’ Nano Measurement Arsenal Expands with New Laser Confocal System

January 2017: Q-PLUS Labs expands its extensive nano measurement capabilities with the introduction of a new laser confocal microscope for non-contact measurement. Using supremely high accuracy laser scanning, this system is extremely versatile and able to perform color profilometry as well as precise measurements down to .5 nanometers (500 picometers)! The system's speed of data acquisition has an incredibly fast response time and can characterize surfaces for accurate measurement results with high-resolution and low noise on a variety of objects, even almost to the "equator" on difficult to measure spherical shapes!
