Glass that has minimum reflection and absorption at 1550nm

Click For Summary
SUMMARY

The optimal glass for minimizing reflection and absorption at 1550nm is chalcogenide glass, which is commercially available and effectively transmits laser light with minimal optical losses. Users are encouraged to consult specialty optical glass manufacturers such as Hoya Optics and Thorlabs for additional technical support and product options. These manufacturers provide resources that can assist in selecting the appropriate glass for laser applications.

PREREQUISITES
  • Understanding of laser optics and wavelengths
  • Familiarity with chalcogenide glass properties
  • Knowledge of optical transmission and reflection principles
  • Experience with sourcing materials from optical glass manufacturers
NEXT STEPS
  • Research the properties and applications of chalcogenide glass
  • Explore the technical resources provided by Hoya Optics
  • Investigate Thorlabs' offerings for optical systems
  • Learn about optical coatings that enhance transmission at 1550nm
USEFUL FOR

Laser engineers, optical designers, and anyone involved in the development of laser systems requiring minimal optical losses at specific wavelengths.

I am building an enclosure for my laser that emits at 1550nm. I need to integrate a window for the laser light to pass through. Anybody have any recommendations on what kind of glass would work best so that the optical losses are kept at a minimum? Ideally, it would be commercially available and not be too expensive. Thanks.
