Custom LED Lens Manufacturer for Lighting Projects
Asahi Optics provides custom LED lens design, optical simulation, lens structure design, mold tooling development, sample testing, small-batch trial production and mass production for lighting manufacturers in Europe, the United States and global markets.
Custom LED Optics Designed Around Your Luminaire
Asahi can develop custom optical lenses according to your LED package, PCB layout, optical requirement, fixture structure and target lighting application.
Custom optics should start with the luminaire, not a standard lens
Asahi can develop custom optical lenses according to your LED package, PCB layout, optical requirement, fixture structure and target lighting application.
What Can Be Customized
- Beam angle and light distribution
- Lens size, shape and mounting structure
- Waterproof or sealing structure
- Surface texture and optical features
- Optical mold and production tooling
Material Flexibility
Custom LED lenses can be developed with PC or PMMA materials. If your project requires a specific material brand or grade, Asahi can evaluate and source according to your requirement.
- Optical-grade PC lens development
- Optical-grade PMMA lens development
- Customer-specified material brands
- Material selection based on transmittance, thermal and outdoor requirements
