Project Description

opto is a Python module that allows you to control Optotune focus tunable lenses using the Optotune Lens Driver 4. Tested with an Optotune EL-10-30.


Opens the serial port, connects to the Optotune, sets the lens current to 50 mA, and closes the serial port, gently returning the lens to 0 mA current:

from opto import Opto

o = Opto(port='/dev/cu.usbmodem1411')

Alternatively, here we use the with statement to create a sinusoidal transition from minimum to maximum current and back:

from opto import Opto
import numpy as np
import time

with Opto(port='/dev/cu.usbmodem1411') as o:
    current_low = o.current_lower()
    current_high = o.current_upper()
    current_delta = current_high-current_low
    for i in np.linspace(0, 2*np.pi, 1000):


Use pip to install from github:

pip install git+

or clone the package using git:

git clone


Requires pySerial
