Custom Optics & Capabilities Resources Use our helpful tools, guides, videos and other resources to solve your optical design challenges. Optical wedges with rigorously controlled angles manipulate light propagation for intricate beam steering, finely tuned spectral manipulation, and tight dispersion compensation. Custom optics Optical assembly Debris shields LaCroix's step-by-step optical design, volume manufacturing, and rigorous quality control processes bring new levels of precision to your optical system. 1. Optical Design Partner with our Manufacturing Engineers to verify your design or make suggestions on optimizing it for manufacturability and performance. 2. Grinding, Polishing Planar parts are processed in one of two ways: single-sided with multiple parts blocked on flat tools, or double-sided using specialized machines that process both sides at once. In both cases an oversized blank will be generated, fine ground, then polished. 3. Processing Coming off the pitch lap, the finished surface will be protected and the second surface will be processed. Parts off the double-sided polisher will continue through the plant for further processing. In-house precision tooling induces angles in optical wedges. LaCroix's Production Technicians to optimize the manufacturing process with a combination of CNC and conventional manufacturing methods. Special proprietary alignment devices are used to ensure the optical axis of the different elements can be maintained within seconds.
