What is the significance of ideal etalon transmission?

Etalons are used as narrowband filters in various applications, including spectroscopy and telecommunications. The transmission peaks of an ideal etalon are very narrow, allowing for high spectral resolution. This means that the etalon can distinguish between very closely spaced frequencies. The transmission peaks of an etalon depend on the optical path difference between the two reflecting surfaces. By changing this path difference (for example, by changing the spacing between the surfaces), the transmission spectrum of the etalon can be tuned. This makes etalons useful in tunable filter applications.
