Product Description

This kit is a combination of the popular 1.7W 445nm Laser Diode Component and the 2.0 amp adjustable laser driver with the OEM power cord.  This does NOT include a power adapter.  You must provide a 12V power supply with at least 2 amps of available current to run.

This includes everything you need to get your laser up and running in your product or project.  Just add the power supply (12V recommended) with enough current and you are ready to go.  We now even cable the laser with a Mini Fit Jr. connector at 2.5 feet to make it even easier to hook everything up!  The kit includes:

Laser Specifications:

This multi transverse mode laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink.  The laser is set in the heat sink with thermally conductive paste.  The front of the component contains a adjustable glass focusing lens for the laser output.  The laser has an ABSOLUTE MAXIMUM of 1.7W and should only be run at this level for very short times.  Additional cooling techniques would be advisable if you want to run for extended periods at this high power.  1 amp at 1W will allow for longer “on” times and will not degradate the laser as quickly.  Thermal issues are the number one reason for catastrophic failure of the laser.  while the mounting case provides heat sinking capability for the laser diode, it is up to the consumer to make sure the laser is operating effectively within these limits.

Driver Overview:

2.0 Amp Version

This version of the popular High Current Laser Driver offers up bigger regulators, bigger power adapter, more capacitance, more resistors, and more options for current limits.  It includes the OEM Power Connector with Cable 6′ 18AWG – Straight to easily connect to a DC power supply of choice.  There is a 3 volt drop across the regulators, so choose a power supply to be above your laser diode voltage plus at least three volts.

This kit does NOT come with an included power adapter.  Feel free to choose an associated power adapter from the accessories section of www.jtechphotonics.com or from any other supplier.

This driver will provide 2.5 amps of constant regulated and protected current to the diode. Configurable current limits with jumpers for 0.5, 1.0, 1.5, and 2.0 amp settings and adjustable output with an analog trim pot. It also can be remotely controlled with an opto isolated input with a super huge range of acceptable voltages for turning your driver on and off. Does your equipment in your project or system that you want to interface with have backwards logic? No problem! There is a jumper for choosing inverted or non inverted logic as well! Perfect for integrating into any final product or project.
