IdealPhotonics' motorized pinhole rotary wheel is an automated optical component integrating an adjustable pinhole array (e.g., Ø50μm-2mm multi-specification) and motor drive (stepper/servo). Through programmed switching, it achieves precise pinhole size selection (repeatability ±2μm) and millisecond-level response, making it suitable for high-precision optical path systems requiring dynamic aperture control, such as confocal microscopy and beam collimation.Features include multi-aperture rapid indexing (e.g., 6/12 apertures), high concentricity (<5μm deviation), and a dustproof sealing design. It also includes RS232/USB communication interfaces and vibration-resistant locking, meeting the repeatability and efficiency requirements of automated experiments.
