PMMA offers superior optical clarity and UV stability but is more brittle. Polycarbonate (PC) is tougher and handles higher temperatures, making it better for harsh environments, though it may have slightly lower light transmission.

Precision optics for beam shaping and light distribution
What are Lenses components?
Lenses are critical for controlling LED light output, enabling beam collimation, diffusion, or focused projection. Selection depends on the LED footprint, required beam angle, material thermal stability, and mechanical mounting constraints within the enclosure.
How to Choose Lenses Components
Selecting the right lens requires balancing optical performance with mechanical integration.
Beam Angle
Define the required FWHM (Full Width at Half Maximum) to ensure the light spread matches your application, from narrow spots to wide floods.
Material Selection
Choose PMMA for high clarity, PC for impact resistance and higher heat tolerance, or silicone for extreme thermal environments.
Mounting Method
Verify if the lens uses snap-fit, adhesive, or mechanical holders to ensure alignment with the LED source.
Efficiency
Check transmission rates; high-quality optics minimize internal reflection losses to maximize total luminous flux.
Compatibility
Ensure the lens geometry is compatible with the specific LED package size and emitter array layout.
