Single Side Compound Eye Lens Microlens Array

Key Features

Single-sided compound eye lenses are array-style optical microlens arrays, “one side is flat, the other is covered with tiny sub-lens units”. They control light through the cooperation of multiple sub-lenses. Here’s what makes them stand out:

• One-sided light control: Focus or uniform light, choose one: The flat side sticks to devices (easy to install), and the compound eye side (sub-lens side) can accurately focus light (narrow spread-out light) or make light uniform (turn strong light into even light). No need to flip the lens for one-way light control—fits compact devices.
• Multi-unit cooperation, high efficiency: Each sub-lens controls light independently, then combines the effect. For focusing, multiple sub-lenses collect light simultaneously, resulting in 30% brighter images than a single lens. For uniform light: after refraction by multi-units, light uniformity is ≥90%—no bright or dark spots.
• Ultra-thin and light, saves space: Total thickness is usually 1mm-5mm (half thinner than traditional lens groups), weight is light (≤0.1g per square cm). Fits into small devices like phone modules or micro sensors—no extra space needed.
• Tough and anti-fading, wide use: Made of BK7 glass or fused silica, transmittance for visible light is ≥92%. Handles -20℃~+80℃, transmittance drops by less than 2% per year with long use. Works from consumer electronics to industrial testing.

Common Uses (Real Scenes You’ll Get)

Consumer Electronics & Displays

• Mini projectors: Focus-type single-sided fly-eye lenses make the projector’s light brighter by 40% (after multi-sub-lens focusing), and the screen edge won’t be dark.

• Testing: Uniform-light fly-eye lenses turn the test light into even surface light. Shining on parts (plastic/metal), flaws (scratches, color differences) won’t be hidden by light and shadow—cameras recognize them more accurately.
• Laser marking positioning: Focus-type fly-eye lenses split the laser into multiple small spots, covering the marking area at the same time. Marking speed is doubled, and no overheating damage from single spots.

Medical & Bio-Optics

• Medical endoscope lighting: Mini single-sided fly-eye lenses are installed at the probe tip. They turn cold light into even light—no “too bright areas or dark areas” when lighting internal tissues, helping doctors diagnose more accurately.
• Bio-sample imaging: Focus-type fly-eye lenses focus excitation light on samples. Multi-sub-lenses collect light at the same time, making fluorescence microscopes catch sample signals faster—testing time is cut in half.

Lighting & Sensing

• Smart car lights: Uniform-light fly-eye lenses are installed in daytime running lights. They turn LED light into even long-strip light—no glare to oncoming cars, and can control light range (only light the road, not the sky).
• Distance sensors: Focus-type fly-eye lenses narrow infrared light into thin beams. Detection distance is 50% longer than ordinary lenses—phone screen-off and automatic door sensing are more sensitive.

How to Choose (3 Simple Steps)

First, decide “use”: Focus or uniform light?

• Need to focus light (e.g., laser positioning, sensors): Choose focus-type, small sub-lens units (0.05mm~0.5mm) for more concentrated focus.
• Need uniform light (e.g., lighting, testing): Choose uniform-light type, more sub-lens units (50×50 or more) for more even light.

Next, check “size”: Will it fit?

• Small devices (mini probes): Choose overall size ≤10mm×10mm, thickness ≤3mm—leave 0.2-0.5mm installation gap.
• Large devices (projectors, industrial testers): Choose overall size ≥20mm×20mm—easy to connect to light sources and imaging parts.

Finally, check “environment”: Is the material tough?

• High-temp/UV scenes (near industrial furnaces, UV testing): Choose fused silica—resists high temps and UV aging.
• High-demand scenes (medical, research): Choose sapphire—hard, scratch-resistant, and can be disinfected for repeated use.
