Zero Field Cavity
-
Zero field cavities generate a zero magnetic field in an air gap. They are mainly used to calibrate hall probes for their zero scale value of output for the magnetic field strength H or the magnetic flux density B they measure. For example Gaussmeters can be calibrated by using Zero Field Cavity.

Resister Blackjack
-
Resistor blackjack is like regular blackjack but better! Your goal is to assemble a single resistance from several resistors that is as close to 21k while not being over.Unlike regular blackjack, the resistors can be combined in series and in parallel, giving the game a whole new dimension. Plus, resistors have tolerances so achieving a mathematical 21k doesn't guarantee a win.

Resist Processing Systems
-
The EVG100 series resist processing systems establish new standards in quality and flexibility for photoresist coating and developing. Designed to provide the widest range of process variations, the EVG100 series’ modularity offers spin and spray coating, developing, bake and chill modules to suit individual production requirements. These systems accommodate the processing of an extensive range of materials such as positive and negative resists, polyimides, double-sided coating of thin resist layers, high viscosity resists, and edge protection coatings. These systems can handle more than one substrate size, from 2" to 300 mm diameter, rectangle, square or even irregular shaped substrates, with no or very short tooling time. This allows the development of new devices or processes on an industrial level, which not only requires high flexibility but also controlled and repeatable processing. EVG has built up many years of spin and spray coating experience for demanding applications and incorporates this knowledge into the EVG100 series, where our process know-how can be leveraged to support our customers.
