IdealPhotonics' Precision Pinhole Kits are optical components consisting of high-precision micropores (1-1000μm in diameter) and rigid supports. They enable beam spatial filtering, wavefront shaping, or point source generation through sub-micron aperture control.Features include a high-precision micropore array (sub-micron aperture), strict tolerance control, and multiple material options (such as stainless steel/laser processing). These kits are suitable for beam collimation, spatial filtering, and optical system calibration.
