PA/FSL
Pinhole Diameter
Zoom

Mounted metal foil with a pinhole or slit 400μm or less. Used in spatial filters, laser diffraction experiments and microscopic magnification correction.

◦A precision etching process creates holes with high circularity and slits with high parallelism.
◦For YAG lasers (1064nm) and CO2 lasers (10.6μm), pinholes made of high copper coated with gold should be used.
◦Pinholes and slits are pre-mounted in aluminum frames for ease of handling and mounting.

Guide

▶Contact our Sales Division to purchase unmounted pinholes or slits.
▶When an aperture φ1mm or above is required, use an iris diaphragm (IH).
W4039
▶Custom pinholes can be made to order.

Attention

▶Dust can obstruct the light through a pinhole. Use and optic bulb blower to remove the dust. Canned air may break tear the foil.
▶Take care when handling unmounted pinholes. The foil is thin and fragile.
▶The holes and slits are only visible under high magnification.
▶For fixed slits, when the number that represents the width of the slit is at the bottom, the long side of the slit is oriented in the horizontal direction.
▶Pinholes can be damaged if the laser power is higher than the laser damage threshold.
