CC02-A
The comparator circuit box performs real-time comparison of optical signals against a user-defined threshold and generates TTL outputs accordingly. It also offers direct TTL 1 and 0 outputs for controlling common lab instruments.
It is well-suited for Real-Time Precision Opto-Control (RPOC) applications, including biomolecular control, cell sorting, and integration with other modalities for real-time decision-making.
How to add RPOC to your laser scanning microscopy systems with the comparator circuit?
Adding RPOC functionality to your microscope is straightforward. All you need is a comparator circuit and, optionally, RPOC control software.
Photokinesis offer advanced RPOC software developed in both LabVIEW and Python.
Additionally, you can select from a variety of laser sources to serve as action lasers. The comparator circuit is typically used in conjunction with an acousto-optic modulator (AOM) to deflect the action laser, or it can directly control the laser itself.
