watec¶

The object which takes photos with the optical Watec camera looking at the sample.

In Pylatus Script editor the watec object is already imported into Python interpreter.

Instance methods:¶

snap

snap¶

watec.snap(name=None, dir=None)

Creates a sequence action to save the next camera frame as a JPEG named name in dir. The dir is relative to the experiment root; if it is None, the photo is saved into the experiment root itself. If name is None, the photo is named after its timestamp.

A snap is practically instant, but rarely the camera hangs for about 10 s.

A photo every second for 20 s, each named after its timestamp:

for i in range(20):
    watec.snap(dir='photos')
    diffractometer.sleep(1)
