Abstract: An optical module according to the present embodiment includes: a first lens array unit in which a plurality of first lenses configured to collect irradiating light are arranged; a second lens array unit which includes a plurality of second lenses and on which signal light from the first lenses is incident; and a plurality of beam splitters configured to reflect irradiating light to the first lenses and to transmit the signal light from the first lenses, wherein reflectance of the beam splitter on a nearest side in a travel direction of the irradiating light is set lowest and the more toward a far side in the travel direction, the higher the reflectance of the beam splitters.
