Python interface to Optotune focus-tunable lenses

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.

Examples

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')
o.connect()
o.current(50.0)
o.close(soft_close=True)

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):
        o.current(np.sin(i)*current_delta+current_low)
        time.sleep(0.01)
