Easy, all-in-one beam steering solution draws a big crowd at Photonics West 2016
Victor, NY — March 8, 2016— The M3-RS-U two-axis beam steering system with built-in controller was the most popular demo in our booth at Photonics West and Bios 2016. Here are a few of the questions that we answered most often at the show.
Q. Where is the controller?
A. Inside the module! This is not what people expect and sets a new standard for the industry. No more separate boxes or big green printed circuit boards! With the M3-RS-U there is no external controller. It’s all inside. Learn more about the M3 Smart Module design platform
Q. How is this better than a galvo system?
A. There are several advantages to the M3-RS-U system:
- It is smaller – the stage itself is smaller, AND we’ve eliminated the external controller. This is a big advantage for people trying to create smaller, handheld or portable systems.
- It has no jitter and holds absolute position with power off. This is a big advantage when you want to move a beam to a fixed point and hold it there.
- It has all-in-one simplicity. See the previous question!
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). Consult this application note for more information.
Q. What is the repeatability?
A. The closed-loop repeatability of the mirror position is +/- 2 encoder counts or +/- 0.05 degrees.
Q. How much does a Developer’s Kit cost?
A. Beam steering kits are $3,450 for a two-axis kit with mirrors and laser, and $1,980 for a one-axis kit with mirror. M3-RS-U Rotary Smart Stages are also sold separately with volume pricing available.
Q. Where can I buy one?
A. Developer’s Kits are currently available from New Scale – call (595) 924-4450 or email email@example.com. Kits will be available from DigiKey and Mouser in Q2 2016.
