The 485-02-15 mirrors much of the functionality of our 4302 LaserSource, with 2 Amps and 15 Voltages of output capability. With a lower cost and smaller footprint, the LaserPak fits better into embedded applications and other low cost applications.

High Compliance
The 485-02-15 features a high 15V compliance for higher voltage applications, such as LED testing or quantum cascade lasers (QCLs), as well as excellect performance with lower voltage laser diodes.

Analog or Computer -- Your Choice
The 485 Series LaserPaks provide both a robust analog interface as well as computer control (USB or RS232) for precise remote operation (you can even use both interface simultaneously). The analog interface provies on/off control, status, and analog monitor of current and voltage, while the computer interface provies complete control over all operating parameters.

Analog Modulation
The 485-02-15’s analog interface supports modulation rates up to 65kHz.

  • 2A range
  • 15V compliance
  • 0.1mA resolution
  • <60uA noise
  • USB and RS-232 interfaces

Develop with a LaserSource,
Deploy with a LaserPak

The LaserPak is command-set compatible with the LaserSource an also features the identical laser interface. This means you can start your development with the LaserSource, a robust benchtop instrument with a full user interface and display, then move to the lower cost LaserPak as you roll out the application to production or your end-users.

Simple Multi-Channel System
Using the 1402C-RM Rack Mount Tray, you can quickly rack groups of 3 or 5 Paks into a rack for a quick multi-channel system.

USB & RS232 Computer Interfaces
Includes for USB and RS232 computer interfaces standard.

Field Configurable AC Input
The LaserPak is configured in the factory for either 115V (485-02-15-115) or 230V (485-02-15-230) operation, but can be reconfigured in the field for either voltage.
