摘要：
A hologram lens manufacturing apparatus includes: a separation unit that separates a light beam emitted from a light source into a reference light beam and an irradiation light beam; an irradiation light irradiating unit that collects the irradiation light beam so as to have a focal point at a predetermined focal position, and irradiates a hologram recording element located on the way to the focal point with the irradiation light beam; and a reference light irradiating unit that irradiates the hologram recording element with the reference light beam under a predetermined irradiation condition to record an interference pattern occurring between the irradiation light beam and the reference light beam as a hologram.
