1064 nm band gratings

PING - Polarization independent (low PDL) gratings for 1064 nm band

Main characteristics:

  • Fused silica transmission gratings
  • Production technology: Holostepper (Holographic stepper) and RIE etching
  • 1064 nm band is defined as 1055 nm - 1085 nm (but can be OEM customized)
  • 100% dielectric materials - No polymers, epoxies, gelatins or metals
  • Grating chip thickness: 0.625 mm
  • Operating temperature at least 500° C
  • Packaging: Packed in semiconductor grade Gelpak containers, sealed in class 10 cleanroom
