An optical apparatus is disclosed, which is suitable for the focus detection by the TTL phase difference detection method, and capable of producing a pair of phase difference images for focus detection with high accuracy. The optical apparatus comprises a deflection optical element which deflects at least one of first and second luminous fluxes with respect to the other. The first and second luminous fluxes are transmitted respectively through first and second areas of an exit pupil of an optical system, and then reach a photoelectric conversion element. The deflection direction of the luminous flux is different from the division direction of the first and second areas.

In an upper waveguide structure (14), a width (W1) of the upper portion is larger than a width (W2) of the lower portion. The upper waveguide structure (14) has a side face (14a) which obliquely extends from an edge portion (14b) of the upper face to an edge portion (14c) of the lower face to come close to a normal (PA1) passing through the center of a light receiving surface (2a) of a photoelectric conversion unit (2). A gap (11) in the air gap structure (AG1) is formed by etching a first insulating layer (4a l: see FIG. 4A) serving as a first interlayer dielectric film (4a) so as to expose not an inner region (2a1) but an outer region (2a2) on the light receiving surface (2a) of the photoelectric conversion unit (2).

There is provided an optical apparatus that provides quick and precise TTL phase difference detection and pupil slicing focus detection. An optical apparatus includes a first optical element for splitting a first polarized light component contained in light that passes an exit pupil of a first optical system and directs to a photoelectric conversion element so that the first polarized light component direct to different light-receiving areas on the photoelectric conversion element. The optical apparatus may further include a second optical element for separating a second polarized light component contained in the light from said first optical element, from the first polarized light component.

An optical apparatus is disclosed which can reliably form AF images and split the AF images to provide excellent focus detection performance in the phase difference detection method. The optical apparatus comprises a light deflection unit including a deflection optical member. The deflection optical member deflects at least one of a first luminous flux and a second luminous flux relative to the other, the first and second luminous fluxes passing through a first area and a second area in the exit pupil of an optical system, respectively, and forming images on a photoelectrical conversion element. The light deflection unit comprises a light-limiting member which limits an image-forming area where at least one of the first and second luminous fluxes emerging from the light deflection unit forms the image on the photoelectrical conversion element.
