Freedom Technologies

Product Details

Freedom Technologies offers the complete line of
Aeroel™ laser non contact optical micrometers . The design
of these optical micrometers is based on the latest developments
in scanning laser technology, resulting in an optical micrometer
which provides stable measurements to a very high degree of
accuracy. These laser micrometers can measure round, and non
round parts while in process. The “quadraline’
optical micrometer is designed specifically for the measurement
of non round and rectangular parts.

The optical micrometers are grouped into major industrial
categories. Within each category, appropriate application
software, hardware, fixtures and accessories are available,
making the product line complete for each specific application.
As a result we offer the user a complete solution and not just a
laser micrometer. The categories are; mechanical, extrusion, wire
and cable, specialty (magnet) wire, and Intelligent (OEM) laser


Freedom Technologies has a wide range of products to chose from
in the Laser Micrometer department. They have kindly broken down
their catalogue by product applications:

Wire and Cable

The Mechanics category includes laser micrometers for both bench
top and on-line diameter measurements. The machine tool industry
requires sophisticated feedback systems to obtain a constant
process accuracy. The laser micrometer has proven itself to be a
necessity in improving efficiency of NC lathes and centerless
grinding machines.

For the extrusion market, we offer both single axis and dual axis
laser micrometers. All of these laser micrometers are designed to
provide on-line control of extruded products. A special version
(Quadraline) enables the measurement of extruded or rolled
products with rectangular shapes.

The two families of laser micrometers designed for the extrusion
process are called the Extruline and Quadraline laser
micrometers. Each laser micrometer includes a laser gauge head
and a micro control unit. Both families are briefly discussed


Wire and Cable Industry

On-line diameter measurements are performing a very important
role in the wire industry today. With the ever increasing demands
on higher tolerances, measurement techniques which yield
real-time diameter and ovality measurements to a high degree of
accuracy are necessary. To meet that demand, the laser micrometer
is rapidly becoming a required instrument in the production
process of wire and cable products. The laser micrometer offers
wire drawing operations a solution to enhance the process, reduce
scrap and improve the quality of the end product. Several system
configurations are offered to accommodate both dry or wet drawing
machines, single or multiple lines, and ferrous or non ferrous

Laser Micrometer Product Overview

Automatic Laser Measuring Station
Because of the high accuracy, Digital Signal Processing (DSP) and
high scanning frequency of the XLS laser micrometers, a fast and
very accurate automatic measuring station is available. This
Profilab system is the most advanced automated measuring system
on the market today.

he Profilab system is built upon the Super Meclab and an
automated linear slide system. The Profilab can measure diameter,
roundness, taper and runout of cylindrical sections. In addition
effective cutting diameter of fluted cutting tools and
straightness of parts can be measured. You can position the part
to a specific desired location to a resolution of ± 5

The top photo to the right shows the scan of a spool valve. The
spool valve is held on centers and was scanned in seconds. The
resulting measurement locations are depicted in red lines. To
scan a part like a spool valve, it takes approximately 10
seconds. Up to 250 measurements can be made on a part. Parts can
be held with a variety of fixtures, centers, adjustable V blocks,
and rotating fixtures, etc..

Cutting Tool Measurement System
A complete cutting tool system utilizing the Super Meclab and a
manual position slide makes up a cutting tool measurement system.
You can measure maximum diameter, minimum diameter, average
diameter, diameter range, effective cutting diameter,
concentricity and measurement position. The cutting tool is
rotated by a stepping motor. Both odd and even fluted tools can
be measured with the system.

The XLS laser micrometers have a number of exclusive features
which enable these high precision measurement systems. These
exclusive features included in the Super Meclab are:

  • Permanent auto calibration, the laser gauge never needs
    calibration due to drift.
  • Auto compensation due to thermal drift of ambient
    This includes the ability to store thermal calibrations for
  • Multi point calibration. The user can use an infinite number
    masters to put in his or her own calibration, which also will
  • A digital oscilloscope is included to see the waveform of the
