Precision Etalons for Lasers and Spectroscopy

Fabry - Perot Etalons
IC Optical Systems Ltd
IC Optical Systems can manufacture and configure Fabry-Perot etalons for many applications. We manufacture both fixed gap etalons and etalons with piezo electric spacers that allow the etalon cavity to be scanned. For piezo tuned etalons we can offer either open or closed loop controllers.

Frequently Asked Questions

Etalons are used in optical systems to control and stabilize the wavelength of light. They are commonly used in laser stabilization, spectral filtering, and wavelength calibration applications.

Etalons consist of two parallel reflecting surfaces separated by a fixed distance. When light passes through the etalon, interference between the surfaces causes certain wavelengths of light to be transmitted and others to be blocked. The distance between the surfaces determines the resonant wavelength of the etalon, which can be used to select and stabilize specific wavelengths of light.

When choosing an etalon, consider factors such as the required spectral resolution, bandwidth, and transmission characteristics of your application, as well as the stability and repeatability requirements. Consult with an optics expert or manufacturer to ensure that you choose the right etalon for your application.

There are several types of etalons available, including air-spaced etalons, solid etalons, and Fabry-Perot etalons. Air-spaced etalons consist of two parallel glass plates separated by air, while solid etalons consist of two parallel plates made of the same material. Fabry-Perot etalons use a combination of reflecting and transmitting surfaces to achieve high spectral resolution.

Low-finesse etalons have a lower spectral resolution and a broader bandwidth, while high-finesse etalons have a higher spectral resolution and a narrower bandwidth. The choice of low-finesse or high-finesse etalon depends on the specific requirements of your application, including the desired spectral resolution and the stability requirements.

Our etalons category offers a selection of precision etalons for laser and spectroscopy applications. Etalons are interference filters consisting of two parallel reflecting surfaces separated by a fixed distance, which causes interference of light between the surfaces. These etalons offer high spectral resolution and stability, making them ideal for use in optical systems requiring precise wavelength control. Explore our selection and find the right etalons for your needs.
