FIT Series Nanosecond Q-Switched DPSS Laser (Air-Cooled & Water-Cooled UV)
Description & Introduction
The FIT Series Nanosecond Q-Switched DPSS Laser is designed for high-precision industrial applications requiring stable beam quality and reliable long-term performance.
Air-Cooled FIT Model
Featuring a lightweight and compact structure, the air-cooled version measures only 339×140×144 mm and weighs just 5 kg, making it ideal for integration into compact laser systems. It maintains excellent optical performance comparable to water-cooled models and operates reliably in extreme environments from -5°C to 40°C.
Water-Cooled UV Model
The water-cooled UV version is even more compact at 264×139×114 mm, with a total weight of only 4 kg. It offers over 30% average power margin, ensuring long-term stability and extended service life. Built on advanced DPSS nanosecond Q-switched technology, it delivers superior beam quality with proven reliability.
The FIT series is an ideal solution for precision marking, micromachining, electronics processing, and high-end manufacturing applications.
