The delta stage is a 3D printed x-y-z translation stage. As the optics do not move it is particularly suited to more complex imaging (phase, reflection, fluorescence microscopy).

3D printed parts

• Some delta stage depending on your required configuration
• choose transmission delta stage depending on your required configuration
• choose reflection delta stage depending on your required configuration
• choose transmission and reflection delta stage depending on your requried configuration
• 3 feet All three feet are in the one file. All three feet are in the one file.
• 1 Raspberry Pi & Sangaboard base
• 0 simple base
• 2 sample clip Both sample clips are in the one file. Both sample clips are in the one file.
• 3 gear All three gears are in the one file.
• 3 small gear All three gears are in the one file. All three gears are in the one file.

Main steps

1. Printing the components
2. Assembling the actuators

Optional Components

1. Attaching the sample clips
2. Attaching the motors
3. Reflection illumination
4. Transmission illumination
5. Connecting the electronics

Software

1. You can control your microscope using the OpenFlexure software.
2. You will need to adjust the configuration file, so that the software knows which stage you are using. More information coming soon..

Bases

There are three optional bases to choose from:

1. Simple base: Short; matches the footprint of the OpenFlexure Delta stage. Best suited if you have small motor controllers, or just want more stability.
2. Raspberry Pi base: Taller; Custom designed base to fit the Raspberry Pi and leaves room for a optics module. Best suited if you want to just use a Raspberry Pi for the camera and are controlling the stage by hand or with small motor controllers.
3. Raspberry Pi and Sangaboard base: Tallest; Custom designed base to fit the Raspberry Pi and Sangaboard. Best suited if you want the fully automated OpenFlexure Delta Stage Microscope.
