parallel rays
解釋
平行光束-
A parabolic concave mirror can converge parallel light rays to its focus, and also collimate light rays that pass through its focus
拋物面凹鏡會把平行而來的光線聚集在一點焦點，亦會把源自焦點的光線平行向外反射。 -
Telecentric operation ( field rays leave parallel to optical axis, unlike barlow lenses which diverge rays )
遠心手術（場射線離開平行光軸，不像巴盧鏡片，其中發散射線） 。 -
A range in relation to an optical system, such as a camera lens, representing distances great enough that light rays reflected from objects within the range may be regarded as parallel
（聚焦區）無限遠與光學系統（如照像鏡頭）有關的一個范圍，表示距離是如此之遠，以至於從在這一距離的物體上反射回來的光可以視為平行光線 -
