Northvale, NJ — October 16th, 2013 — Inrad Optics has introduced a new quick ship program for industry-standard interferometer transmission flats. The transmission flats can be configured online and will be express shipped.

The quick ship program applies to 4-, 6- and 12-inch transmission flats. Options include:

  • Coating choices. The transmission flats are available uncoated, with a standard coating or with a custom coating based on evaporative vacuum coating processes—both Ion Assist and Plasma Assist E-Beam.
  • Mounting choices. Transmission flats are available as standalone optics or mounted in ring-style mounts. Mounted flats fit industry-standard Fizeau interferometers for easy replacement and installation.

Each transmission flat is packaged in a PET-G container for unmounted glass or in a wooden box when mounted to the designed ring.

Inrad Optics fabricates all transmission flats from highly homogeneous, bubble-free fused silica, which is then polished to the interferometric standards required by precision optics manufacturers. Our deep understanding of interferometry allows us to produce finished optical surfaces that conform to the most demanding technical requirements related to surface roughness, sub-surface damage, optical coating consistency and birefringence.
