title: Discussion to the angular aperture narrowing behavior inside AOTF crystal.
abstract: An off-perpendicular incident arrangement is suggested and tested in AOTF system design to improve the spectrum resolution and angular aperture. A special discussion is given to the "equivalent point design" of Si=56ø where the optimum design parameters are reached.
