Pinholes are made of very thin metal foil, only 0.01mm thick, which is the thinnest thickness. As we all know, the thinner the pinhole material, the sharper the picture.
In order to eliminate the burr, we use laser to pierce, and repeat 15 times to make the edge of the pinhole smooth.
Pinhole size：0.1mm / 0.15mm / 0.2mm / 0.25mm / 0.3mm / 0.35mm / 0.4mm / 0.45mm / 0.5mm / 0.6mm / 0.7mm / 0.8mm / 0.9mm / 1.0mm
