Optical polishing to Ra<0.1μm. 92% light transmission.
Acrylic Surface Finishes
From as-machined to optical-grade polished, we offer finishes to match your application requirements.
As-Machined Finish
Visible tool marks, matte/frosted appearance. Most cost-effective option for non-visual parts.
Semi-Polished Finish
Buffed edges with translucent clarity. Good balance of cost and visual quality for functional parts.
Optical Polish Finish
Crystal-clear transparency with mirror-like edges. Essential for light pipes, lenses, and premium displays.
Common Acrylic Applications
Light Pipes & Guides
LED light distribution, indicator lights, backlit panels
Optical Lenses
Camera housings, protective windows, magnifiers
Display Cases
Museum displays, retail showcases, electronics enclosures
Lab & Medical
Flow cells, sample holders, microfluidic devices

Acrylic Machining FAQ
Can you achieve water-clear edges on machined acrylic?
Yes. We offer optical polishing that produces crystal-clear, water-clear edges with a surface roughness of Ra < 0.1 μm. This is essential for light pipes, lenses, and premium display applications.
What's the maximum thickness you can machine?
We can machine acrylic up to 50mm thick from standard sheet stock. For thicker parts, we can laminate and bond multiple sheets. Our max part envelope is 1200mm x 600mm x 50mm.
Do you offer colored or tinted acrylic?
Yes. We stock clear, frosted, black, and white acrylic. Custom colors and tints (including fluorescent and specialty grades) are available on request. Lead time may be slightly longer for specialty materials.
