We present modeling and performance of a solid, fused silica, 3-mirror Fabry-Perot-type etalon. 3-mirror etalons have been known for decades to have superior theoretical performance but for the first time we demonstrate an etalon with sufficient quality to realize the benefits of the more complex design. 3-mirror etalons have better passband shape and higher contrast ratio enabling significantly improved wavelength separation. We show the optical cavity design and construction of the new etalon and show >95% peak transmission, improved passband shape and 20 dB better out-of-band rejection than a similar 2-mirror etalon.
我们展示了一种固态熔融石英三镜法布里 - 珀罗型标准具的建模与性能。几十年来，人们一直知道三镜标准具具有卓越的理论性能，但我们首次展示了一种质量足以实现这种更复杂设计优势的标准具。三镜标准具具有更好的通带形状和更高的对比度，能够显著改善波长分离。我们展示了这种新型标准具的光学腔设计与构造，并表明其峰值透过率大于95%，通带形状得到改善，与类似的两镜标准具相比，带外抑制提高了20分贝。
