Automatic Pockels Linearization

Some time ago, we described a procedure to manually create a look up table for the laser power slider to achieve linear power.  Now, if you have a Thorlabs’ PM100D meter your job has been made much easier, as Scanbox can perform the calibration automatically. As a first step, you will need download and install the…

Simultaneous control of an electrically tunable lens and a pockels cell

We are preparing Scanbox for fast, volumetric scanning, by providing simultaneous control of an electrically tunable lens (to focus on different planes) and a Pockels cell (to control laser power). The Scanbox card has an integrated, 12-bit current source used to control the focus tunable lens. Similarly, an integrated DAC on the Scanbox card controls laser power via a Pockels cell. The…
