Product Description
Introducing our CNC-Machined Acrylic (PMMA) Housing and Optical Component Set, engineered for manufacturers who demand high transparency, tight dimensional accuracy, and premium finishing. Each part is milled from high-purity PMMA and processed through a precision-controlled machining workflow to ensure maximum clarity and performance.
These components demonstrate advanced engineering features, such as uniform surface texture, mirror-like clarity, and uniform screw-seat machining with metal inserts for enhanced strength.
Perfect for optical systems, camera modules, sensor housings, LED illumination units, and testing fixtures.
Engineered with reliability in mind, these PMMA parts maintain stable geometry, resist cracking, and provide long-term optical performance under demanding operating environments.
Applications
· Optical light guides and diffusion modules
· Transparent mechanical housings
· Camera and sensor windows / covers
· LED illumination components
· Optical testing fixtures and jigs
· Prototype and pilot-run transparent parts
