640nm 500mW TO CAN With PD Laser Diode

 

Features:

• 640nm 500mW, built-in PD for real-time power detection
• Standard TO CAN hermetic package, good airtightness
• Low divergence angle and excellent beam quality

Applications:

• Laser Positioning & Line Laser Module: Ideal for laser level, cross line generator and industrial positioning marking devices. The integrated PD enables real-time power feedback to keep laser brightness consistent all the time.
• Machine Vision Auxiliary Lighting: Used for barcode scanning, product surface defect detection and visual inspection systems. 640nm red light delivers high imaging contrast under normal ambient light.
• Medical Physiotherapy & Beauty Instruments: Applied in red light phototherapy and skin care small medical devices. Real-time PD power monitoring ensures stable output and improves treatment safety and repeatability.

This 640nm 500mW TO CAN laser diode integrates an internal monitor PD to realize real-time optical power monitoring and automatic power stabilization, featuring stable red wavelength output, reliable hermetic TO packaging and excellent beam performance. With low power consumption, compact structure and outstanding long-term working stability, it is easy for secondary development and automatic assembly. It is widely adopted in laser positioning modules, machine vision illumination, medical physiotherapy equipment and optical experimental instruments, offering a cost-effective and high-reliability red laser diode solution with built-in power monitoring function.
