Component Specifications

Definition
Aperture plates are precision-engineered components featuring precisely machined openings that regulate the passage of light, electrons, or other particles in detection systems. They serve as critical elements in optical and electron microscopy, spectroscopy, and particle detection equipment by defining beam size, shape, and intensity for accurate measurement and analysis.
Working Principle
The aperture plate operates by physically restricting the passage of particles or radiation through precisely dimensioned openings. In detection systems, it controls beam characteristics by blocking unwanted peripheral signals while allowing the central beam to pass through defined apertures, thereby improving signal-to-noise ratio, resolution, and measurement accuracy.
Materials
Stainless steel (304/316), aluminum alloys (6061-T6), copper alloys (C11000), or specialized materials like tungsten for electron applications. Surface finishes typically range from Ra 0.4-1.6 μm with optional coatings (gold, nickel, or anti-reflective treatments).
Technical Parameters
  • Flatness <0.01 mm
  • Thickness 0.5-5.0 mm
  • Tolerance ±0.005 mm
  • Surface Finish Ra 0.4 μm
  • Aperture Diameter 0.1-10.0 mm
  • Operating Temperature -20°C to 150°C
Standards
ISO 10110, ISO 14999, DIN 3140
