ETALON Thermal Stability Filter 1525-1565nm

Xiaoxiao Photon's thermal stability filter is based on advanced ETALON technology, utilizing unique optical and mechanical design, and advanced packaging technology to ensure the stability of the filter's wavelength under extreme environmental conditions, including temperature and humidity. We have unique technically recognized technology to ensure that the target accuracy of the filter's wavelength in all environments is within ITU+/-1.25GHz for selection. This ITU aligned filter can be used for channel monitoring and wavelength locking in wavelength division multiplexing (WDM) systems. We also have special technology available for customers to choose specific wavelength corresponding accuracy. This filter is divided into transmissive and reflective types according to different usage methods. Its unique design ensures a wide range of choices for standard precision, channel spacing, and operating wavelength. The heat stable filter designed for customers can be well compatible with various spectral applications, including telecommunications, wavelength reference and calibration, fiber optic sensing systems, testing and measurement, and laser wavelength stability control.

Fabry Perot (F-P) interferometer/etalon 2.5-14um/1.3-2.0um

The Fabry-P é rot interferometer is a multi beam interferometer composed of two parallel glass plates. The inner surfaces of the two glass plates facing each other have high reflectivity. When two glass plates are fixed with hollow spacers of fixed length, it is also called a Fabry Perot standard or simply referred to as a standard. The F-P (Fabry Perot) standard is a high-resolution spectroscopic instrument due to its high reflectivity of flat plates and extremely narrow oblique interference fringes of multiple beams. Can be used for high-resolution spectroscopy and studying spectral lines with very close wavelengths, such as isotope spectra of elements, hyperfine structures of spectra, small frequency shifts in light scattering, Doppler shifts in spectral lines caused by atomic movement, and structural shapes inside spectral lines; It can also be used as a high-resolution optical filter and for constructing precision wavelength meters; In laser systems, it is often used to compress narrow spectral lines inside the cavity or to operate the laser system in a single mode. It can be used as a bandwidth control and tuning device in broadband picosecond lasers to analyze and detect the spectral (longitudinal and transverse) components in the laser
