Custom Optics Solutions for Precision Manufacturing

Standard optics work well for many applications. Custom optics exist for the cases where they don't. Common drivers include unusual form factors or packaging constraints, wavelength or spectral requirements outside catalog ranges, thermal or environmental conditions that affect performance, integration with sensors, housings, or illumination systems, and performance targets that depend on system-level behavior. Custom optics are rarely about pushing theoretical limits. They are about making real systems work reliably.

Custom optical development often includes optical design and tolerance analysis, material selection based on wavelength and environment, geometry optimization for manufacturability, coating selection and validation, and mechanical integration considerations. Successful custom optics are designed with manufacturing and validation in mind from the start, not retrofitted later.

Custom optics may be produced from glass, optical polymers, crystalline or specialty materials, or coated or hybrid substrates. Material choice affects optical performance, thermal behavior, durability and lifetime, and cost and scalability. Material decisions are rarely reversible later without redesign. This is why they must be made early and realistically.

A custom optic that cannot be manufactured consistently is not a solution. Manufacturing considerations include achievable tolerances for the chosen process, tooling and process stability, scalability from prototype to production, and inspection and validation methods. Designs that ignore manufacturing capability often succeed once — and fail at scale.

In custom optics, performance is often limited by sensitivity to small dimensional changes, alignment and mounting behavior, and environmental variation. Sensitivity and tolerance analysis are essential to identify true performance drivers, avoid over-specifying non-critical features, and control cost and yield. The goal is predictable performance, not perfect geometry.

Many custom optics require coatings to manage reflection and transmission, define spectral behavior, and improve durability or cleanability. Coating selection must account for substrate compatibility, stress and thickness limits, environmental exposure, and lifetime expectations. A coating that works on one material or geometry may not work on another.

Custom optics must be validated against real operating conditions, not ideal assumptions. Validation may include optical performance testing, environmental exposure, thermal cycling, and durability or lifecycle testing. Validation data should reflect how the optic will actually be used, mounted, and maintained.

Custom optics are typically justified when system performance depends strongly on optical behavior, integration constraints rule out standard components, volume supports tooling and development investment, and long-term stability matters more than initial cost. They are not always the right answer — and knowing when not to go custom is part of good engineering.

Rather than asking 'Can this be custom made?', engineers should ask: What problem is the custom optic solving? What performance truly matters? What constraints are fixed? How will this be manufactured repeatedly? How will performance be validated over time? Clear answers to these questions lead to successful designs.

We achieve tolerances down to 0.002mm concentricity, surface finishes of 1.5 nanometers RMS, and surface figures of <¼ wave peak-to-valley in metals and <½ wave in polymers.

We utilize both single-point diamond turning (SPDT) for prototyping and precision components, and high-volume polymer injection molding for production-scale manufacturing with advanced metrology throughout.

Our custom optics serve medical devices, aerospace and defense systems, automotive applications including LIDAR and sensors, VR/AR displays, lighting systems, and consumer electronics requiring precision optical performance.

We work with PMMA, polycarbonate, polystyrene, cyclic olefin polymers (COP/COC), ULTEM, and metals including nickel, brass, copper, and aluminum, selecting materials based on optical and environmental requirements.
