  • Anti-reflection coatings are also available at your specified wavelength.
  • Sapphire transmits ultraviolet light, but sometimes exhibit fluorescence when subjected to powerful ultraviolet sources. For this reason, they are best suited for use with visible to infrared wavelengths.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
