1. An optical apparatus comprising:
an interface housing comprising:
a guide part defined by an interior space of the interface housing and configured to guide an object to a measurement position; and
a pressurizing part configured to induce congestion of a second portion of the object by pressing a first portion of the object when the object is disposed within the guide part; and
a measurer comprising:
a light source provided on an upper side of the guide part and configured to emit light to the second portion of the object when the object is at the measurement position; and
a detector provided on the upper side of the guide part and configured to measure a bio-signal from the second portion by detecting light scattered or reflected from the second portion,
wherein the pressurizing part comprises:
a plate configured to contact the first portion of the object; and
an elastic member that is connected to the plate and configured to deform as the first portion presses the plate,
wherein the interface housing further comprises a braking part configured to reduce movement of the plate caused by pressing of the first portion of the object, and
wherein the braking part comprises:
a first locking part connected to the plate and including a projection; and
a second locking part connected to the interface housing and having a groove configured to couple to the projection based on the first locking part being moved.
