The optical profilometer mainly measures two-dimensional coordinates, including geometric elements such as lines, circles, arcs, rectangles, and the length, angle, contour, and surface shape of parts. It can also make three-dimensional auxiliary measurements, such as hole depth and surface flatness.
High Restoration, Fast Focus, Precise Imaging Professional Choice
High-Precision, Space-Saving Intelligent Measurement Solution
Profilometers are widely used in precision manufacturing, quality control, and scientific research fields, such as testing engine parts (pistons, gears) in the automotive industry, analyzing wafer surface morphology in the semiconductor industry, and evaluating the accuracy of artificial joints in medical devices. They also support mold reverse modeling and scientific research experiments. They are the core tools for measuring surface profile, roughness and form and position tolerances, and help facilitate high-precision product design and process optimization.

Q1: What is the difference between a profilometer and a roughness meter? ​​
A1: Profilometer: can measure the complete surface profile and multi-dimensional parameters (such as angle, groove shape), with more comprehensive functions
    Roughness meter: dedicated to surface roughness (Ra/Rz) measurement, portable and low cost.
Q2: What parameters can the Profilometer measure? ​​
A2: Basic parameters: Ra (roughness), Rz (maximum profile height), straightness, roundness, angle, groove depth/width, etc.
Advanced analysis: complex geometric features such as surface fitting, groove center distance, convexity, logarithmic curve, etc.
Q3: What are the main types of profilometers?
A3: Stylus profilometer: High accuracy, but may scratch soft materials.
Optical profilometer: Non-destructive testing, suitable for precision optical components or brittle materials.
Laser profilometer: High-speed scanning, suitable for dynamic or large-sized objects.
Tips: What parameters does the profilometer mainly look at?
Roughness Parameters: Ra (average roughness), Rz (peak-to-valley height), Rt (maximum roughness).
Geometric Parameters: straightness, roundness, convexity, groove width/depth, groove curvature radius.
Profile Analysis: logarithmic curve, profile, horizontal/vertical distance.
