From Optical Prototype to Production

Optical manufacturing is the process of designing, fabricating, finishing, coating, measuring, and assembling components that control light. It can include lenses, mirrors, diffractive surfaces, microlens arrays, optical filters, and complete assemblies. At Apollo, manufacturing methods include single-point diamond turning, polymer injection molding, thin-film coating, precision metrology, and assembly selected around the product’s optical requirements and planned volume.

The transition begins with confirming that the prototype meets functional requirements and that its tolerances, materials, and geometry can be reproduced economically. Apollo performs design-for-manufacturing review, tolerance analysis, and verification before selecting fabrication methods. Diamond-turned prototypes can prove a concept, while injection molding, coatings, assembly fixtures, and appropriate inspection plans support repeatable production at the required scale.

Single-point diamond turning is especially useful when a program needs small quantities of custom optics, complex aspheric or diffractive surfaces, or rapid prototype evaluation before committing to molding tooling. Apollo can diamond turn plastic and metal materials and produce components from 1 mm to 300 mm in diameter. The method provides a practical bridge between optical design and production planning.

Yes. Optical-grade polymers can provide strong light transmission, low birefringence, chemical resistance, dimensional stability, heat resistance, or cost advantages depending on the selected material. Apollo works with acrylic, styrene, Zeonex, Zeonor, Ultem, polycarbonate, and other specialty polymers. Material selection should consider wavelength range, environment, sterilization needs, optical geometry, production volume, and target performance.

Apollo provides thin-film coatings for polymer and glass optics, including anti-reflective, filter, mirror, and beamsplitter coatings for UV, visible, and NIR ranges. Polymer coating requires careful attention to temperature limitations and substrate behavior, which differ from glass processing. Coating selection is based on the intended wavelength range, reflectivity target, environmental demands, and component geometry.

Tolerance analysis determines how normal variation in optical surfaces, mechanical features, materials, and assembly affects overall system performance. It helps engineering teams balance required performance against manufacturing capability and cost before production begins. Apollo combines optical and mechanical perspectives to identify critical tolerances, reduce avoidable risk, and create designs that can be manufactured and assembled consistently.

Verification can include simulation, prototype testing, dimensional measurement, surface profiling, interferometry, microscopy, roughness analysis, and polarization measurement, depending on the component. Apollo’s in-house metrology equipment measures both mechanical and optical characteristics. Comparing prototype results to design specifications helps reveal aberrations, surface issues, or assembly concerns before a program proceeds to production tooling or volume manufacturing.

Yes. Apollo assembles polymer-based optical products ranging from UV-cemented doublets to multi-element systems, including 34-element endoscopes. Available methods include mechanical assembly, UV bonding, ultrasonic welding, manual prototype setup, semi-automatic fixturing, and automation for higher volumes. Assembly approaches can support glass-polymer hybrids, refractive-diffractive systems, opto-medical devices, and opto-electronic products under ISO, FDA, and GMP protocols.
