Laser Micrometer Systems for Precision Non-Contact Measurement
A laser micrometer is a precision measuring tool that uses laser scanning technology to accurately measure the diameter, width, or thickness of a part without making physical contact. These advanced measurement systems are widely used in manufacturing and laboratory environments where accuracy is required.
Unlike traditional contact measuring tools, laser micrometers can capture dimensional data quickly and consistently while reducing the risk of part deformation or measurement error.

What Is a Laser Micrometer?
A laser micrometer is an optical measuring device that projects a laser beam across a target area. It calculates dimensional characteristics based on how the object interrupts or blocks the laser light.
Laser micrometers are commonly used to measure:
1. Outside diameters
2. Wire and cable dimensions
3. Tube and pipe diameters
4. Thickness measurements
5. Edge positioning
6. Part profiles
7. Continuous production materials
Laser micrometers rely on optical scanning rather than physical contact. This makes them an ideal solution for applications with measurement variability.
The Mechanics of a Laser Micrometer
A laser micrometer operates by projecting a precisely controlled laser beam toward a receiver. When a part passes through the measurement area, the instrument detects the beam and accurately calculates the object's dimensions.
This measurement process provides:
1. Non-contact inspection
2. High-speed measurement capability
3. Excellent repeatability
4. Micron-level precision
5. Reduced operator influence
6. Real-time process monitoring
Many modern laser scan micrometers can integrate directly with quality control systems, automated production equipment, and statistical process control software.
Different Micrometers for Different Measurements
Understanding the different micrometer styles available can help you choose the most effective measurement solution for your inspection, machining, or quality control application.
Laser Scan Micrometers
Laser scan micrometers use advanced optical scanning technology to perform highly accurate, non-contact measurements. These systems are commonly used for measuring diameters, thicknesses, widths, and profiles in manufacturing, laboratory, and automated inspection environments where precision and speed are critical.

Tube Micrometers
Tube micrometers are designed specifically for measuring wall thickness and dimensions of tubing and curved surfaces. Their specialized anvils allow accurate measurements in applications where standard micrometers may not provide sufficient access.
Blade Micrometers
Blade micrometers feature thin measuring faces that allow users to measure grooves, keyways, narrow slots, and recessed features with greater precision than standard micrometers.
Gear Tooth Micrometers
Gear tooth micrometers are engineered for measuring gear tooth thickness at the pitch line, making them valuable tools for gear manufacturing, inspection, and quality assurance applications.
Screw Thread Micrometers
Screw thread micrometers utilize specialized anvils and spindles to accurately measure thread pitch diameters and verify threaded components during manufacturing and inspection processes.
Point Micrometers
Point micrometers feature pointed measuring contacts that allow access to narrow grooves, recesses, and hard-to-reach surfaces where traditional flat anvils may not fit.
Disc and Ball Anvil Micrometers
Disc micrometers and ball anvil micrometers are designed for measuring thin materials, curved surfaces, tubing, and specialized workpieces that require alternative contact geometries for accurate readings.
Interchangeable-Anvil Micrometers
Interchangeable-anvil micrometers provide added versatility by allowing users to swap measuring contacts for different applications, helping reduce the need for multiple dedicated measuring tools.
For additional specialty measurement solutions, Penn Tool Co. also offers V-Anvil Micrometers, Spline Micrometers, Groove Micrometers, Hub Micrometers, and other specialized micrometers designed for industrial environments.
