Electroformed Diaphragm Piece Processing and Application Fields

1. Product Introduction

Electroformed diaphragm pieces are high-precision optical light limiting and shading components manufactured through advanced photolithography and electroforming integrated molding technology with high-purity nickel and nickel-cobalt alloy as base materials. Free from mechanical stamping and laser cutting stress, the products achieve micron-level aperture and pattern accuracy with vertical, smooth, burr-free and distortion-free openings, effectively solving the defects of traditional etched and laser diaphragms such as position deviation, rough edges and uneven thickness. They support one-piece molding of micro round holes, special-shaped holes, multi-array holes and ultra-thin sheets with excellent thickness uniformity. Featuring high flatness, superior light shading and low reflectivity, the diaphragms deliver high dimensional consistency and are suitable for mass production. Widely applied in precision optical imaging, inspection equipment, laser devices, medical optoelectronics and semiconductor optical path control, they serve as core precision accessories for accurate light control and filtering in high-end optical systems.

2. Product Features

• Stress-Free Integrated Molding: Integrally formed by photolithography electroforming without mechanical cutting, stamping extrusion or laser thermal damage. Zero internal stress ensures no warpage, deformation or displacement during long-term service.

• Ultra-High Position Accuracy: Micro holes, array holes and special-shaped holes are formed in one step. The vertical and smooth hole walls feature burr-free and collapse-free edges with no secondary finishing required, achieving extremely high pattern replication accuracy.

• Controllable Ultra-Thin & Uniform Structure: Customizable ultra-thin specifications with excellent overall thickness uniformity and high flatness, meeting the assembly requirements of narrow spaces in precision optical paths.

• Excellent Optical Performance: Available with blackening and matte anti-reflection treatments to enhance light shading and stray light suppression, effectively improving the accuracy of optical imaging and detection.

• Powerful Customization: Supports customized circular, square, polygonal, irregular and multi-group array aperture structures. Non-standard precision diaphragms can be produced with customized molds according to actual demands.

3. Product Performance

• Dimensional Accuracy Performance: Adopts micron-level precision control with aperture tolerance up to ±0.002mm and hole spacing tolerance of ±0.003mm, ensuring high overall dimensional consistency and minimal batch errors.

• Optical Shading Performance: Blackened surface delivers high light absorption and extremely low reflectivity, effectively shielding stray light and diffuse reflection to realize precise optical path control without light leakage and astigmatism.
