Metrology and Manufacturing

The scale and diversity of Thorlabs' product portfolio allow us to invest in a comprehensive suite of metrology equipment essential for both the development and manufacturing. Our optomechanical design and manufacturing teams leverage diverse technologies to ensure the dimensional accuracy and quality of motion of our optomechanical offerings. Moreover, they have access to the optical inspection equipment needed to measure the performance of the component when used in an application. Tailored to the specific product, our testing capabilities encompass a wide spectrum, including assessments for environmental durability, vibration resistance, lifetime expectancy, thermal performance, damage threshold, and more. This comprehensive approach ensures all products undergo rigorous evaluation to meet the highest standards of quality and reliability. Some of the key metrology resources for our optomechanical group include:

  • Touch Probe CMM
    • Touch probe CMM machines are instruments for checking dimensions on a wide range of machined parts. They can be programmed for use in continuous monitoring of manufactured parts and used on-the-fly to inspect a first-piece prototype. They also support a range of inspection needs for measuring dimensions in precision subassembly.
  • Vision Systems
    • Vision systems have evolved rapidly in the last decade and are now used to perform many inspection processes. Once programed, they can measure dimensional tolerances to nearly the same precision as a CMM in a fraction of the time. They are used to easily inspect and sort components, validate engraving, and, with some systems, evaluate surface quality and wear.
  • Interferometer
    • Many of the products and components in the photonics industry must be tested at the micrometer and nanometer level. For these inspection processes, we frequently use specialized interferometric instruments. For example, when we measure the performance of a linear stage, we use an interferometer to examine the pitch and roll deviation from perfect motion over the stage's range of travel. For a mount that holds an optic, an interferometer ensures that the mount is maintaining the surface flatness of the optic, or in some cases, is not creating stress induced birefringence.
  • Gauges, Surface Plates, Hand Tools
    • Gauges, surface plates, calipers, dial gauges, and other tools continue to play an important role in the precision manufacturing of photonics components. All of our metrology equipment is meticulously maintained, and we have a robust process to ensure that their certification status is kept current through scheduled calibrations.

Manufacturing Capabilities

Thorlabs continually invests in the expansion and modernization of our manufacturing capabilities. Our software provides real-time reporting on the status of our machinery, which ensures that our production output stays on schedule and meets our customers' needs. Below is a partial list of the vertical manufacturing capabilities available to our optomechanical design group.

From start to finish, any given component manufactured by Thorlabs is touched by more than a dozen people. Each person in the process is empowered to identify any potential quality issues regardless of whether it affects their operation. By embracing a total quality approach to our manufacturing, we strive to provide the highest caliber optomechanical components in the photonics industry.

3- and 5-Axis Vertical Mills

Vertical mills are an extremely versatile resource for Thorlabs. We use them to prototype designs, produce initial production runs as the main production line is tooled and validated, and as the main production resource for a wide range of components. Many of our vertical mills have some form of automation that allows them to operate continuously during a shift, and in some cases, between shifts. The automation solutions vary from simple two-pallet systems to 60-pallet systems that can be swapped in and out without tooling or setup.

Horizontal Mills

Thorlabs has invested extensively in the optimization of our horizontal milling centers for use in the photonics market. We have implemented tooling solutions that provide cost and quality advantages to our customers, whether they need a high volume of a single component or a large mix of components in low volumes. Once the initial investment is made in the fixturing and tooling, Thorlabs can efficiently machine the needed components and implement production ramps by duplicating the setup on additional spindles.

Swiss Screw Machines

Our Swiss Screw Turning Department specializes in single point turning applications. For example, we manufacture fine adjustment screws and bushings that are used in our own products as well as sold directly to our customers. The superior performance of a Swiss Screw Machine in terms of deflection and vibration of the material for small parts is important for components with demanding tolerances. This paired with our specialized vision system for turned parts allows us to design and manufacture solutions that a traditional lathe could not accomplish. Our Swiss Screw Machines are equipped with bar feeders that maximize production capacity, thereby minimizing costs.

Lathes

Our Lathe department is the main producer of turned components. We handle a wide range of bar stock and select new lathes optimized to specific components. In 2019, for example, we purchased a lathe with live tooling on both the spindle and subspindle. This addition enabled us to produce a large number of components in one operation, rather than needing to be turned and then milled. As a second example, in 2022, we purchased a lathe that had a small working volume and no live tooling options. The benefit of these features is a reduced cycle time on turned parts like our SM05 lens tube line. Carefully selecting the jobs that run and their order can significantly reduce the setup time and optimize the cost to produce a component.

Wire EDM

In 2018, Thorlabs added a Wire EDM Department, positioning us to manufacture components unable to be made using a mill or lathe. The wire EDM machine ablates conductive material by passing a current from a wire through the material being cut. Since this is a slow, non-contact method of removing material, the wire EDM machine can hold tolerances that would be difficult to hold otherwise. Additionally, the size of the features that can be created are only limited by the diameter of the wire. Material hardness is an advantage, not a limitation, of the wire EDM. The wire EDM can be used to cut hardened steel just as easily as aluminum.

Tumbling and Bead Blasting

While post-machining finishing processes typically receive little attention, we consider them integral to the final product. Our finishing departments have a range of tumbling and bead blasting options that let us remove tooling marks from aluminum and steel, while maintaining the dimensional tolerances of the component. These techniques produce mirror-like finishes on hardened stainless steel.

Passivation and Anodization

Thorlabs has fully automated passivation (for stainless steel) and anodization (for aluminum) lines in our manufacturing facility. Managing this capability in-house reduces lead times, enables tighter quality control, and optimize finishes for specific products or customers. Many of our vacuum-compatible products are made from stainless steel; by controlling what enters our passivation system, we can ensure that contaminants are never introduced into the passivation line due to a prior customer’s run.

CNC Grinding

The ability to CNC grind surfaces allows us to achieve the surface flatness and quality that are critically important to the performance of certain types of optomechanical products, such as linear stages.

Laser Engraving

Nearly all products are engraved with a logo, part number, or serial number. By having this capability in-house, we can control the cost and minimize the time it takes to perform the operation. Custom engraving is available for many components.
