Frequently Asked Questions

The Vacuum Cell Spatial Filter is designed to improve laser beam quality by removing noise and creating a smooth intensity profile.

Pulsed lasers have high peak power, and a vacuum cell is the only alternative to focus the laser beams into a pinhole without causing damage.

No, a microscope objective cannot be used to focus pulsed laser beams into a pinhole due to COD (Center of Distortion) issues.

The Vacuum Cell Spatial Filter is available in various cell diameters ranging from 5 mm to 38 mm and lengths from 100 mm to 1500 mm.

The pinhole is made of titanium or stainless steel, and the windows are made of BK7 or UVFS glass with coatings for optimal performance.
