Technological Capabilities

Optomechanical Assembling

Altechna offers a full range of assembly and manufacturing solutions, from exact build-to-print projects based on customer’s instructions, to fully custom-designed solutions that are tailored to fit the specific end-user needs:

  • Optical parts: prisms, waveplates, lenses, and other glass parts optically contacted or cemented together.
  • Optomechanical parts: optics mounted on various types of metal mounts and housings, either fixed or shifting.

Optomechanical solutions are designed and manufactured in-house to fit your specific needs.

Type of work offered

We offer a variety of assembly and manufacturing solutions in ISO 6 cleanroom environment. Starting with exact build-to-print projects based on customer instructions, and ending with fully custom-designed solutions, these are tailored to fit the specific end-user needs.

 

Any work is accompanied by:

  • Rapid reviews of project needs by a dedicated engineering team
  • A design-to-cost mentality
  • A clear information flow, strict deadlines, and full customer involvement
  • Quality control pre- and post-manufacturing, all carried out in-house
  • Full traceability of each manufacturing stage

Our goal is to provide a service whereby we can help the end-user to gain the following additional benefits:

  • Time and resource savings: the complex, multi-stage processes required to build optomechanical sub-assemblies demand a large amount of internal resources and time.
  • Simplicity: the pre-built, aligned, and cleanroom-packed modules can immediately be incorporated into the users’ systems.
  • Increased yield: reducing customer headaches from damages to precision optics when being built into assemblies.
  • Space-saving: with goods coming from Altechna, a company‘s own cleanroom areas and manufacturing lines can be reallocated to other projects.
  • Cost saving: a skilled team of technical experts is ready to help with your needs for the most competitive price on the market.
