Our laser and amplifier module generates a laser light for the optical probes, receives the light back from the probe, and converts the light to an analog voltage.
Picture Above: Laser and Amplifier Module configured with a single laser, 2 detectors, and 2 voltage output
This module is controlled via command line functions through a DB9 connector in the back of the unit. Controls allow the user to modify the laser power, the gain of each detector (which can be set to auto-gain or to a fixed gain), and switch between AC and DC coupling.
This module has two optical-to-electrical conversion circuits, and either one or two laser circuits.
Voltage output is -5V to +5V via BNC connectors.
Configuration
Several modules are available with various lasers, detectors, and connectors. Below are the main parameters:
Available lasers:
| Description | Power | Wavelength | Class | Comments |
| Single Mode Red | 60 mW | 660 nm | 3B | 1 or 2 lasers per module |
| Low Power Red | 100 mW | 635 nm | 3B | 1 or 2 lasers per module |
| High Power Red | 300 mW | 635 nm | 3B | 1 laser per module only |
| High Power Blue | 400 mW | 450 nm | 3B | 1 laser per module only |
Available optical connectors:
- ST (bayonet type), or
- FC (screw type)
Other connectors could be wired upon request.
Available amplifier gain:
- Regular gain range: 20 to 1,120
- High gain range: 160 to 8,960
Standalone or Packaged
This module can be used either as a standalone unit or packaged in a Sensor Interface Unit.
As a standalone unit, the laser and amplifier module requires a 12V power supply.
Up to 8 modules can be packaged in a Sensor Interface Unit (SIU). When packaged in an SIU, the settings of each module can be controlled in a web browser via an Ethernet connection.
