HF-100

HF-100 product family is an ultra-high-finesse reference optical resonator. Utilizing a proprietary IBS deposition and post-processing technique, we grow ultra-low-loss optical thin films with absorption-scatter loss below 1 ppm on superpolished mirror substrates. We offer two options for the cavity spacer block, ultra-low-expansion glass and thermally-compensated composite spacer. 

  • Finesse: up to > 500,000

  • Wavelengths: 600 - 1500 nm

  • Cavity spacer: ULE glass, composite spacer

  • Zero-crossing temperature: 295 K

  • Mirror substrate: fused silica, ULE

  • Options: PZT tuning, CRDS report, custom spacer design
