Abstract
An optical apparatus captures imaging light entering into an imager to acquire an image of an object. The optical apparatus includes a lens module and a support. The lens module is configured by a combination of two or more lenses, captures the imaging light through the lenses, and focuses the captured imaging light on the imager. The support supports the lens module at a position apart from the imager by a predetermined distance, such that the imager and the lenses are aligned on the optical axis, and a focal point of the imaging light is formed on the imager. The support is formed such that an expansion-contraction ratio, at which the support expands or contracts along the optical axis in accord with changes in ambient temperature of the optical apparatus, becomes a first expansion-contraction ratio at which the support expands or contracts so as to cancel a movement of the focal point occurring in the lens module along the optical axis in accord with the changes in ambient temperature of the optical apparatus.
