Laser Diodes can be attached to the ACRO system mounting plate as well as other tools and accessories - use at your own risk!
Please note: There are lot of great choices when it comes to laser diodes, so be sure to pick the right one for your application. Power choice is important as well as making sure your diode supports PWM.
The ACRO multi mounting plate hole pattern is designed to accommodate many available diodes. If the diode you choose has a different mounting pattern you can easily drill holes in the acrylic to mount.
Please discuss the diodes that you use in the discussion for the ACRO
