High performance optics
Light shielded miniature electron gun
50 or 100 mm z-retraction (optional)
Integral multi-segment shutter (optional)



Product Description:
The SPECS reverse view ErLEED optics was originally designed by the University of Erlangen-Nürnberg (Lehrstuhl für Festkörperphysik). 20 years of continuous development have lead to its current high perfomance specifications. The ErLEED 100/150 is exclusively manufactured by SPECS. In order to achieve the highest possible quality and performance of each optics we select materials and components very carefully and put great emphasis on the quality of the mechanical and electrical manufacturing. As a result SPECS now offers an improved retraction mechanism with unique reliablity and minimized outgassing rates due to reduced friction.

Optics are available on DN100CF and DN150CF flanges (ErLEED 100 and ErLEED 150 respectively) with 2, 3 or 4 grids. For both optics integrated retraction mechanisms and multi segment shutters to protect the optics are available. Two power supplies are offered: our analog version ErLEED 1000A for LEED only and the fully digital version ErLEED 3000D for LEED/AES.
