AT-F7-AIR

The AT-F7-AIR is ideal for high precision scans with a fixed aperture. AT-F7-AIR is part of the ESRF-Type X-RAY slit family and was initially designed and developed by ESRF engineers and scientists to address the need for compact, reliable, high-precision slits with sub-micron resolution. The design is now licensed to JJ X-Ray.

The slit system holds four motors which set the position and the opening of the aperture. For each dimension, one motor defines the aperture opening, and another determines the position of the aperture. Because only one motor is moved during a one-dimensional scan, the AT-F7-AIR is the optimum choice for high precision scans with a fixed aperture.

A distinctive feature of the AT-F7-HV and AT-F7-AIR slit systems are the flexible positioning of their 7mmx7mm aperture due to a total translation travel range of 14 mm.
