Product Specification
The silicon fly-eye lens is placed inside the machine for use in the light path system and is an important part of the reflective equipment. It is also a very useful optical element in the lighting system, which can be used to generate a uniform irradiance distribution. The silicon fly-eye lens is an integrated arrangement of multiple small lenses, and the two fly-eye arrays are arranged in parallel so that the transmitted light is evenly distributed. The key to achieving uniform illumination using a double-row fly-eye lens array is to improve its uniformity and illumination brightness.

How does a LSR fly-eye lens achieve uniform illumination?
If we want to see a moving or still picture through the projector, we need the picture to be evenly illuminated and presented on the screen. Therefore, in order to achieve uniform illumination, the spatial light modulator needs to be uniformly illuminated. Normally, the illuminance distribution of the light source is Gaussian, so it is not possible to illuminate the spatial light modulator directly and uniformly. We have to "De-Gaussianize" the illuminance distribution and change it to a uniform distribution.
The silicon fly-eye lens arrays usually occur in pairs and work together with the spotting mirrors to provide a uniform distribution of the illumination plane. The focal point of each small unit lens in the first fly-eye lens array coincides with the center of the corresponding small unit lens in the second fly-eye lens array, and the optical axes of the two fly-eye lenses are parallel to each other, and the spotting mirror is placed after the second fly-eye lens, and the focal plane of the spotting mirror is placed on the illumination screen to form a uniform illumination system.
Advantages of Silicon Fly-Eye Lens
1. High Light Transmittance The silicon fly eye-lenses can achieve to 92% to 94% light transmittance, without surface coating. |
2. Temperature Resistance The silicone material is flame resistance, and the temperature resistance vary from -40 to over 200 Celsius degrees. |
3. Anti-yellowing After double 85 tests, 5000 hours, the silicon fly-eye lens has no changing. |
4. Cost Effective Comparing to glass fly-eye lens, the production costs is way much lower. |
Liquid Injection Molding Silicon Fly-Eye Lens Application
The silicone fly eye lens is used for projectors, with LSR injection molding, for large volumes, the production costs will be much lower than glass fly-eye lens.

FAQ
Q: What is fly-eye? Q: The fly-eye is composed of tens of thousands of single eye, just like the eyes of dragonflies and flies. The fly-eye is composed of more than 3,000 small eye units that have their own optical systems, which work both in concert and independently. Therefore, the fly eye not only has high speed and high precision resolution, but also can effectively calculate the orientation and distance between itself and the observed object, which is beneficial to make faster judgments and responses. |
Q: Can you design silicon fly eye lens? A: We regret that we mainly do OEM service, we can't design optical lenses for now. |
Q: What shall I offer to custom a silicon fly eye lens? A: Please offer us 2D and 3D drawings with specific light performance requirements. |
Q: What's the lead time to develop a silicon fly-eye lens? A: For prototyope mold, the lead time is 25- 30 days. |
Q: Can I visit your factory? A: Yes, highly welcome to visit us, contact us to arrange the visiting. |
