For replacing HeNe lasers! High-power 633nm semiconductor laser.
The TOPMODE 633 laser is a groundbreaking semiconductor laser light source developed to replace HeNe lasers.
The TOPMODE 633 laser is a groundbreaking semiconductor laser light source developed to replace HeNe lasers. It utilizes the unique CHARM technology, allowing for stable operation while maintaining a single frequency mode over long periods. Its compact housing, measuring 19 cm in length, is also a significant attraction. The output achieves a high power of 50 mW in spatial mode (25 mW in fiber output). In applications using multiple HeNe lasers, it can be branched for efficient operation. The dedicated CHARM controller features a slim design of 45 mm and enables complete PC remote control via USB or Ethernet.
