Here is a list of our standard solid fused silica etalons (we make a lot of custom etalons so feel free to send us a request if these don't meet your needs or you require a thin film coating to enhance the finesse). Solid fused silica etalons are simple devices with a wide variety of applications in spectroscopy and lasers. We have 3 styles of fused silica etalon;
Uncoated 2mm Etalons - Very small etalons that our customers usually cement on one end to a holder. The small size is preferred for use inside small laser cavities
Uncoated 5x5mm Etalons - Slightly larger versions that are easier to manipulate with human hands
Etalons with Dielectric coatings for higher finesse
Solid Fused Silica Etalons Finesse 6, 450nm to 650nm
