Q. Can the stage turn more than 20 degrees?
A. Sure! The stage itself can do continuous 360° rotation. The beam steering kit does 20° since that's the practical limit for beam reflection angles with mirrors, and also prevents the two mirrors from colliding.
Q. Can the stage move a greater mass?
A. Yes. Let us know what you need, and we'll let you know if it's feasible.
Q. What software do I need?
A. You don't need any special software. The developer's kit includes our powerful New Scale Pathway software to get you started. This PC-based GUI receives your commands and communicates with the stage via a USB adapter. For embedded systems your processor and firmware communicate directly with the stage. Which leads to the next question...
Q. How do I send commands to the module?
A. Direct digital or analog servo input. You can use it as a SPI slave, use I2C or UART channels, or use the analog position servo. We provide a reference guide that explains how to connect, set up and communicate with the module through any of these methods - in addition to the USB adapter and included software mentioned in the previous question.
Q. Can I get better than 0.025 degrees resolution?
A. Yes. Closed-loop resolution is limited by the internal position sensor, not the motor. You can achieve better resolution by commanding motor sub-steps (open-loop resolution). Measuring the magnitude of the sub-steps requires an external sensor with better resolution. The typical open-loop resolution is less than 0.0057 degrees (100 microradians).
