Really short user manual (Thanks to Joonas Govenius):
- Turn on projector (without a sample).
- Start software.
- Raise the objective all the way up.
- Put in the objective you want to use.
- Choose objective, resist, and substrate in software.
- Load your design.
- Check that the reported dimensions & pixel size make sense.
- Tweak exposure time.
- Set tonality (positive/negative exposure).
- Insert a dummy sample for focusing (or focus in an unused area of your real sample).
- Move the stage to a reasonable place for focusing.
- Choose "focus mode" (as opposed to "alignment mode"), i.e., blue light.
- Adjust height manually until you get a sharp image in "camera view".
- Go back to "alignment mode" (green light). Note that the image should not be in focus anymore (green and blue wavelengths cannot be simultaneously focused).
- Insert your real sample with unexposed resist.
- Move to the area you want to expose.
- For best resolution, correct tilt.
- For precise alignment, fine tune rotation and position.
- Expose (single pattern or matrix of patterns).
- Turn off projector (when done)!
