1W 405nm Laser and 2.5amp Safety Compliant Driver Kit

$259.99$269.99

This is our new single mode 405nm laser kit offering. The spot size is very small (0.003″ or 0.075mm), allowing for precision cuts and engravings or for use in SLS printing.  The laser comes with our 2.5 safety compliant driver kit.  This kit has similar engraving ability to the 2W 445nm kit because the spot size is so small.

Features:

-Smallest spot size available
-Cut and engrave fine detail

Product Description

Fourth Generation Product – it just keeps getting better!

This go around we have kept all of the features that make this laser kit awesome – precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, esd protection, current limiting, and the list goes on.  But NOW we have more safety in mind as well!  The US Federal Government has a list of things that are required for operating these high power class 4 lasers.  They might seem trivial, but they could save your eyesight!  Here is a run down of the new safety features to protect yourself and others:

  • Key Switch – This key is needed to enable the laser.  When the key switch is turned on, the laser is enabled and the key CANNOT come out.  You can only remove the key when it is disabled.  This feature is good if you have curious children or have your laser in a shared area and want to limit use.  Just take the key out and hide it!
  • Remote Interlocks – This feature allows for addition of switches to your enclosure so when it is open, the laser will automatically turn off.  Also provides for the addition of an E Stop button for the laser, which is always good for if you need to stop the laser super quick!  Add as many switches as you want to make a super safe area for your laser machine so nobody can accidentally look into the laser.
  • Power Fault Protection – This one may seem like it is not needed, but hear us out.  Consider your power goes out in your area where the laser is located.  You were running your program and then everything is dark…  Power doesn’t come back on for awhile… long enough for you to forget that the laser was left ON!  You come back and are checking your laser and boom, the power is back on, right when you are looking straight at it.  Well, don’t worry because the laser will be disabled whenever the power to the driver is lost.  Press the reset button and you are back in action!
  • Emission Indicator –  The small little LED on the front to let you know  your really super bright laser is on…  They require this in case you are using an infrared invisible laser.

What this kit includes:

This kit is a combination of the new 1000mW 405nm Laser Diode Component and the 2.5 Amp matching safety compliant laser driver kit with a 12V adapter.  We now include a pair of safety goggles with every kit as well!  This kit includes everything you need to get your laser up and running in your product or project.    The kit includes:

Laser Specifications:

This single 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 high efficiency glass focusing lens for the laser output.   We advise to run the laser at or under 0.6amps, providing about 900mW to 1W of power.  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

This is the fourth generation of the popular High Current Laser Diode Driver series.  We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation.  This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators.  All of these features make for a safer laser operation and will comply with federal laws regulating such operations.

At the heart of the product are laser trimmed parallel regulators to give constant current without the large temperature dissipation of other regulators. Couple this with inherent safety features like soft starting, current isolation, reverse protection, ESD protection, and thermal shutdown control and you have all you need in a small package.

The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products.  The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics.  This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops.   The board has screw terminal connections as well as Molex mini-fit Jr. connectors for easy connections to external equipment for control and the laser diode output.

Features:

  • High power current source for driving Laser Diodes and Light Emitting Diodes.
  • Current Range of  2.5 Amps.
  • Current Ranges are adjustable in 500ma increments.
  • Integrated cooling fan
  • Soft start for diode protection.
  • Reverse diode and ESD protection.
  • Thermal Protection and Over Current Protection.
  • Federal Compliant Safety Features
  • Key switch, Remote Interlock, Power Fault Reset
  • Compact Size.
  • CW Mode and Input Control Mode.
  • Digitally isolated control input.
  • Control from CW to 5KHz.
  • Configurable Input signal: Inverting /Non-Inverting.
  • Multiple connector options for both Laser/LED output and control input.
  • LED status lights for input laser enabled and laser on.
