Brief introduction of silicone lens

Brief introduction of silicone lens

Silicone lens, silicone lens has good high temperature resistance, can withstand temperature of 300 degrees Celsius, high strength, strong drop resistance, light transmittance is about 94%, but the molding dimensional accuracy is slightly poor, not suitable for high requirements on light distribution accuracy The lens is generally directly packaged on the LED chip.

Liquid silicone rubber(LSR) optical lenese yellowing resistance 2000 times in UV and Resistance to yellow 5000 Hours,

liquid silicone rubber(LSR) optical lenese yellowing resistance ability

What is refractive index of liquid silicone lenses ?

In terms of emissivity, PC is about 1.526, PMMA is about 1.592, and glass is about 1.523, all of which have a certain degree of dispersion, which is easy to cause visual fatigue.

The optical silica gel is 1.41, which can maintain a stable low refractive index in high and low temperature environments and various wavelengths of light, and has a low degree of dispersion, which can achieve high-definition imaging effects.
