MPM300-Digimicro position encoder system is affordable and ideal for custom stage development. The custom stage can be used for single mode optical fiber alignment, general nanopositioning, microscope stages, laser source positioning, laser tuning among many applications that require nanometer to micrometer accuracy.

13 reasons why MPM300-Digimicro position encoder system is ideal for custom stage development:

1. 1-100 nm resolution.
2. 0.7 to 3 um accuracy.
3. 200-500 nm repeatability.
4. 150-500 nm return error.
5. 12-100 mm travel range.
6. Large LCD display for standalone application.
7. USB 2.0 interface for plug and play convenience.
8. Free CP300 software for data visualization and acquisition.
9. Included .NET API for custom application development in software such as Matlab and Labview.
10. PID motion control core with 2 channels of programmable DAC output.
11. USB powered to reduce cable clutter.
12. Plunger system and enclosed scale also reduces performance degradation due to dust.
13. A-Quad-B digital input and output for connectivity to other position encoders and motion controller cards.

Example custom stage for gap measurement.

The image above shows MH-12-MPM Digimicro position encoder being integrated into a custom stage to measure the gap between another position encoder scale and the position encoder head. The graph below shows that a 1 nanometer step can be achieved when the loop is closed using a piezo actuator stack and MPM300 PID motion control core.
