PTL Lasers
Back to Lasers

  • Two year warranty
  • 3 types of fiber endings: FC connector, focusable circular spot or structured light pattern
  • Uniform intensity distribution with line generators
  • Wide range of wavelengths, from 635 nm to 1550 nm
  • ESD, over-temperature, over-voltage, and reverse-polarity protection
  • Rugged, industrial-quality housing

StockerYale’s Lasiris™ PTL series diode laser module is specifically designed to distance the diode laser from the focusing and beam shaping optics by a length of optical fiber. This can isolate and protect the diode from heat or harmful radiation sources. The diode is also protected by passive internal heat dissipation, a rugged housing, and reverse-polarity, over-voltage, over-temperature and ESD protection.

The Lasiris™ PTL laser uses patent optics to generate a uniform intensity line or crosshair. Other patterns are also available. Enquire about our custom designs.
