PRECISION APERTURESPRECISION APERTURES

National Aperture is the leading manu facturer of precision micro-apertures.Our specialty is primarily in the 0.5µm to 1000µm range for round holes, withsizes up to 8,500µm and Slits and patterns up to 25mm square.All aperture e dg es are carefully fabricated employing proprietary computer-ized micro-drilling, micro-slitting and micro-finishing techniques. All fi n i s h e dcomponents are rigidly quality controlled before shipping. Standards are trace-able to NIST.For special needs, we have provided a choice of options at an additional cost.

Some typical applications of our apertures include:

• spatial filtering, • high power laser light control, • gas/liquid flow control, • spectrometry, • fiber optics, • astronomy, etc.
