Challenge

Challenge & Solutions For Light Guide Prototype

01

Internal Optical Clarity

We use specialized diamond milling tools and slow-feed rates to eliminate internal micro-voids, ensuring maximum light throughput without scattering.
02

Intricate Micro-Optics

Using high-precision 5-axis machining, we accurately replicate complex prism arrays and micro-textures that control light distribution across the guide.
03

Surface Haze Reduction

Our multi-stage vapor polishing process removes all machining marks, achieving a mirror-like finish essential for high-efficiency total internal reflection.
04

Thermal Expansion Control

We utilize heat-stabilized PMMA and polycarbonate materials to maintain dimensional accuracy when the guide is subjected to high-intensity LED heat.
05

Complex Mounting Fitment

In-process probing ensures that the light guide’s snap-fit features and housing interfaces are machined to precise tolerances for vibration-free assembly.
