LL-Series 650nm Miniature Laser Diode Modules

The LL-series laser diode module is designed for OEM applications with the lowest cost, miniature size, and beam focusing requirements. Additional heat sink may be needed for LL-series laser module under continuously operating for a long period of time. 

Designed for the OEM, it is ideal for a wide range of low power laser applications, such as general sighting, leveling, and positioning. 


  • Basic Performance and the Lowest Cost 
  • Miniature Design: 9mm Dia. x 18.3 mm L 
  • Fixed Focus or Adjustable Focus
  • Elliptic Beam Shape
  • Automatic Power Control Circuits 
  • Connector: Pin (-) & Brass Case (+)
