Abstract
In a right-handed XYZ coordinate system, a dichroic-mirror array of the present disclosure includes a first group in which m (m≥2) dichroic mirrors DAto DAm are arranged parallel to each other along a positive direction of an X axis and a second group in which n (n≥2) dichroic mirrors DBto DBn are arranged parallel to each other along a negative direction of the X axis. Incident surfaces of the DAto DAm and incident surfaces of the DBto DBn are perpendicular to an XZ plane. A slope of straight lines with normal lines of the incident surfaces of the DAto DAm projected onto the XZ plane are negative, and a slope of straight lines with normal lines of incident surfaces of DBto DBn projected onto the XZ plane are positive.
