Optomechanical components

Development and construction of optomechanical modul kit systems with the following features:

• flexible,
• easy to use,
• cheap,
• compatible to micromodul system from company Linos (former Spindler & Hoyer), 40x40 mm base area and 6mm rod connection system,
• and miniaturized module system woth 20x20 mm base area and 3mm rod connection system (can be integraded directly into devices).

Basicelements

• adjustable translation stages (one- and two degree of freedoms)
• adjustable rotation elements
• adjustable roll and pitch elements
• flexible to use groove base material
• height adjustable mounting stages
