Abstract
In some implementations, an optical assembly includes a first etalon, a second etalon, and an optical element disposed between the first etalon and the second etalon. The first etalon is configured to transmit a collimated light beam from an input surface of the first etalon to an output surface of the first etalon, and to allow the collimated light beam to propagate from an output surface of the first etalon to the optical element. The optical element is configured to receive the collimated light beam, to change the collimated light beam to a de-collimated light beam, and to allow the de-collimated light beam to propagate from the optical element to an input surface of the second etalon. The second etalon is configured to transmit the de-collimated light beam from the input surface of the second etalon to an output surface of the second etalon.
