etalumacontrol 0.1.1

Library for interacting with Etaluma microscopes and stages

etalumacontrol

Introduction

This library provides a simplified Python interface for interacting with Etaluma microscopes and motorized stages (600 and 700 series). Essentially, the code provides a simplified wrapper for Etaluma's own C# SDK using Python.NET. This package requires Python 3.8 (or higher, but Python.NET currently supports only up to 3.8).

Current state and limitations

This library was written to facilitate our own use case, but may also be useful to others. If there's a particular feature that you feel is lacking, feel free to submit an issue or PR. Etalumacontrol has only been tested on our LS720, but should work on any 600 and 700 series microscope. 32-bit versions of the LumaUSB and WSC DLL's are included, but have not been tested.

Installation

You may install etalumacontrol from PyPI by entering the following into a shell prompt, preferably after activating a virtual environment:

py -m pip install etalumacontrol

Sample program

Here's a sample program which moves the stage to a specified position, acquires an image, and displays it on the screen.

from etalumacontrol import EtalumaStage, LumaScope

# use the "with" statement to automatically handle resource allocation
with EtalumaStage() as stage, LumaScope() as scope:
    # move stage to center of microscopy slide
    stage.move('x', -62.9)
    stage.move('y', -38)

    # turn on the brightfield led
    scope.set_led(brightness=20)

    # turn up the gain
    scope.gain = 10

    # set shutter speed to 150 ms
    scope.shutter = 150

    # acquire image and show it
    img = scope.get_image()
    img.show()
