2. STJ Seal-Series 355nm DPSS Lasers

The STJ Seal-Series Lasers includes both UV and green lasers with excellent beam quality and perfect spot characteristics. The whole machine adopts integrated structure design, and the optical path and external drive circuit are integrated, which makes the product have strong anti-interference ability. Optimize and upgrade the fully sealed structure to prevent external dust. At the same time, the isolation of external water molecules make the machine have strong resistance of humidity, making the SEAL series adaptable to harsher industrial environments. In addition, a self-cleaning system in the cavity allows longer lifetime of the machine.
