| Etalons | |
| These Fabry-Perot etalons lead the industry with superior free-spectral-range tolerances to as tight as ±0.001 GHz and optical thickness accuracies of ±1 nanometer. They have been supplied to leading OEM customers and researchers worldwide in telecommunications, aerospace, laser research, and defense. Standard 2x2 mm2 fused silica etalons are available for the 1520–1630-nm wavelength range with 50- and 100-GHz nominal FSR values. Solid silicon, air-gap, Gires-Tournois (GT), VIPA, and multi-cavity versions are also available in a variety of sizes down to 1x1 mm2 and a variety of materials. Main Features:

| Micro Optics | |
| These high-quality custom optics and optical assemblies combine our IBS coatings, ultraprecise fabrication capabilities and epoxy-free, which are widely used in the telecommunications, semi-conductor and biomedical industries. Because of their miniature size, they can be placed right at the objective lens or at the tip of optical fibers and light pipes. Applications:

| Etalons | |
| Serie ET & ETA : The etalons are most commonly used as line-narrowing elements in narrowband laser cavities, and as bandwidth limiting and coarse tuning elements in broadband and picosecond lasers. All etalons describe hereunder are planar fabry-perot type and classified as follows. Air-spaced etalons : Pair of very flat plano-plano plates separated by optically contacted spacers Solid etalons : Parallel sides plano-plano plates with partailly reflecting coatings on both sides. Deposited Solid etalons : A special type of solid etalon in which the cavity is formed by a deposited layer of coating material Applications:
