Frequently Asked Questions

Precision Air Slits are micro-machined from solid opaque material.

Precision Air Slits do not rely on transmission through glass, so they are not wavelength dependent. In addition, there is no coating and hence no possibility of pinhole effects in high power applications.

Precision Air Slits have a diameter of 9.5 mm, a thickness of 13 µm, and a slit length of 3 mm. The dimensions tolerance is ±10%.

The range of slit widths available for Precision Air Slits is 5 to 500 μm.

Precision Air Slits can be used in all the same applications as Optical Slits, including generating a line spread function, as entrance and exit slits in spectrophotometers, and in a wide range of imaging and alignment applications.
