Selection of high-quality base materials: 

Adapted to the requirements of micro-pore diameters Crafted from high-quality materials including stainless steel, copper, Kapton PI, PET and rubber, our Micro Diaphragms cater to diverse application requirements. Metal substrates (stainless steel, copper) offer high mechanical stability and precision, ideal for fixed-aperture applications in industrial and scientific instruments. Polymer substrates (Kapton PI, PET) provide lightweight and flexible solutions for portable devices and micro-electro-mechanical systems (MEMS). Rubber diaphragms offer excellent elasticity and durability, minimizing sound or light distortion in audio-optical applications. All materials are selected for their dimensional stability, corrosion resistance and compatibility with micro-fabrication processes, ensuring consistent performance across extreme environmental conditions.

Precision Manufacturing Process: Ensuring Micro Aperture Accuracy

Our Micro Diaphragms are produced using advanced microfabrication techniques such as photolithography, laser cutting, and chemical etching. Laser cutting provides ultra-precise aperture sizes with a tolerance as tight as ±1μm, ensuring consistent light control. Photolithography enables the production of complex aperture shapes (circular, square, rectangular, custom) with clean, burr-free edges. The diaphragm substrate is processed to achieve high flatness (<λ/4 @633nm), preventing light scattering and ensuring uniform aperture performance. For metal diaphragms, an optional blackening treatment reduces reflection from the aperture edges, minimizing stray light interference in imaging systems. Stringent quality control ensures no pinholes or defects in the aperture area.

Core Performance Advantages: 

Empowering Precise Light Control Ultraopto’s Micro Diaphragms boast exceptional aperture precision and dimensional stability, with long-term performance unaffected by temperature fluctuations (-40°C to 120°C) and humidity. The diaphragms provide precise light intensity control,  while polymer options provide lightweight and cost-effective solutions for high-volume applications. The diaphragms’ versatile design supports both fixed and adjustable aperture configurations.

Full-scenario application coverage: 

Cross-industry micro-light control adaptation Our Micro Diaphragms are widely applied in industrial, medical and scientific fields requiring precise light modulation. In micro-optical systems such as miniature cameras and sensors, they control aperture size to optimize image quality and sensitivity. In medical devices including endoscopes and diagnostic instruments, they regulate light intensity for safe and clear internal imaging. For precision imaging systems such as microscopes and spectrometers, they adjust depth of field and reduce aberrations to enhance resolution. The diaphragms also find use in audio-optical devices, MEMS systems, aerospace sensors and laboratory optical instruments. Their micro-scale design makes them indispensable in modern miniaturized optical technologies where space and precision are critical.
