Product Description: 
The PHOIBOS 150 WAL Analyzer is a true 180° hemispherical energy analyzer with 150mm mean radius.  The analyzer, the lens system, and the detector are surrounded by two layers of 2 mm thick µ-metal to screen external magnetic fields down to an uncritical level.  For ultimate performance, the analyzer and lens system are constructed entirely from non-magnetic materials inside the µ-metal shielding.

The design of the wide-angle deceleration lens uses an entrance mesh with high transparency and an optimized electrode design. The mesh is shaped to produce an image of the sample region that is analyzed at the aperture with negligible spherical aberration. The mesh lens collects electrons emitted from the sample over a cone of up to ±30°. The lens can be operated in different modes for angular studies and high transmission. All lens modes can be set electronically. The standard working distance of 27.75 mm and the ±40° conical shape of the front part of the lens provide optimum access to the sample for all kinds of excitation sources. Trajectories within an angular range of ±30° starting from different positions but with the same angle are focussed on the same location on the analyzer plane.
