Assembly
In addition to precision optical components, Perkins Precision (PPD) also offers mounted optics and optical assemblies. From cemented doublet lenses to high-power, adhesive-free beam splitter cubes to beam expanders and simple ring-mounts, we have the ability to convey the job from your idea to a finished product.
Examples of bonded and/or optically contacted assemblies include polarizing beamsplitter cubes, air-spaced etalon cavities, ring-mounted lenses and windows, multi-element lens assemblies and monolithic prism assemblies.
