Sapphire Laser Cap
Sapphire Laser Cap

Characteristics

  • High strength and high reliability
  • No degradation even with a high power laser
  • Excellent heat dissipation (Thermal conductivity: 40 times that of glass)
  • No variation in the polarization extinction ratio due to the strict regulation of the optical axis (c-axis)
  • High transmittance achieved by excellent AR coating
  • High strength and high airtightness achieved by excellent metallization coating
  • Kovar rings bonding available
  • Special shapes such as square windows and tapered versions available
