940 nm band gratings

PING – Polarization independent (low PDL) gratings for 940 nm band
 

Main characteristics:

  • Fused silica transmission gratings
  • Production technology: Holostepper/lithographic stepper and RIE etching
  • 940 nm band is defined as 915 nm – 980 nm (but can be OEM customized)
  • 100% dielectric materials – No polymers, epoxies, gelatins or metals
  • Grating chip thickness: 1 mm
  • Operating temperature at least 500° C
  • Packaging: Packed in semiconductor grade Gelpak containers, sealed in class 10 cleanroom
