ABSTRACT:
An optical component casing (40) that houses a plurality of optical components including a reflection mirror (424) and disposes the plurality of optical components on a planarly defined illumination optical axis (L1) has a holder (81) that holds the reflection mirror (424) and a housing main body (401) that houses the other optical components. A bulging portion (816) bulging in an out-plane direction of the reflection mirror (424) is formed on a side of the holder (81) opposite to the side on which the reflection mirror (424) is attached, the bulging portion (816) pivotally moving on the inner surface of the housing main body (401) to rotate the holder (81) relative to the housing main body (401), where a rotation center (P) of the holder (81) is substantially coincident with an intersecting point (Q) of the illumination optical axis (L1) and a reflection surface (424A) of the reflection mirror (424).
