Optomechanical Assembling
Altechna has opened a new chapter in its optical manufacturing journey: with an increase in demand for optomechanical and optical assemblies, the company is strengthening and expanding its service by introducing a new line – bespoke assemblies and subassemblies based on customers’ designs:
- 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.
Type of work offered
Altechna offers a variety of assembly and manufacturing solutions. 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 be immediately incorporated into the systems of users.
- Increased yield: reducing customer headaches from damages caused 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.
