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

Details

◦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). WEB Reference Catalog Code/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.
