Laser LGP
The Laser Light Guide Plate (Laser LGP) is a precision-engineered optical component designed to deliver uniform high-efficiency illumination in LED lighting systems. Using laser-engraved dot patterns, our Laser LGP provides exceptional control of light extraction across the surface, resulting in superior brightness uniformity.
Manufactured from optical-grade PMMA with advanced laser processing technology, the Laser LGP is ideal for applications requiring large-area light distribution, high lumen output, and ultra-thin form factors.

LGP Micro-Patterning Technologies
Bespoke Light Guide Plate for every application.
Every LGP is custom-engineered using a proprietary algorithm. By analyzing key variables such as panel dimensions and light-entry points, we optimize the laser dot density for the best uniformity.
Complement Products
Laser LGPs are typically paired with front diffuser sheets (opal, or UGR<19 optimized).
Back reflective sheets improve output by redirecting backward-emitted light toward the front surface, enhancing overall system efficacy.
We provide a complete “optical bundle” to simplify your supply chain and ensure component compatibility.
Applications
Laser Light Guide Plates are used across industries where large-area uniform illumination is critical:
Architectural lighting — backlit walls, feature ceilings, large-format feature panels
LED backlit signage — advertising light boxes, retail displays, illuminated logos
Office lighting — high-uniformity LED panel lights, especially for non-standard format
Automotive — interior ambient lighting, illuminated trim panels, dashboard backlighting
Industrial — machine vision backlight systems, inspection lighting
Medical devices — illuminated diagnostic displays, operating room panels
