## Abstract

An optical apparatus including a housing having a window, the housing configured to accommodate a laser emitting device configured to emit laser pulses to an outside of the optical apparatus through the window; a fan configured to generate an airflow; and a conditioning element having a plurality of fins defining a first portion configured to receive the airflow from the fan, the contoured fins having a second portion curved relative to the first portion.

## Claims

### Claim 1

An optical apparatus comprising:
a cover having a vent hole to allow an airflow into the cover and a cover opening connected to a window;
a housing having the window, the housing configured to accommodate a laser emitting device configured to emit laser pulses to an outside of the optical apparatus through the window;
a fan disposed beneath the housing and configured to generate the airflow;
a conditioning element having a plurality of fins defining a first portion configured to receive the airflow from the fan, the fins having a second portion curved relative to the first portion and configured to direct the airflow onto a window to provide conditioned air to the window;
a frame covering the conditioning element; and
a dual heat sink for removing heat generated by the apparatus,
wherein the housing comprises a base and an inner housing formed on the base,
wherein the base includes a base opening to allow the airflow,
wherein the frame includes a shroud covering the plurality of fins, and
wherein the dual heat sink has a plurality of radiating fins mounted on both one side and an opposite side of the inner housing.

### Claim 2 (depends on 1)

The optical apparatus of claim 1, wherein the fins are accurate and parallel to each other.

### Claim 3 (depends on 1)

The optical apparatus of claim 1, wherein the shroud has an inlet in a bottom surface and an outlet in a side surface.

### Claim 4 (depends on 1)

The optical apparatus of claim 1, wherein the housing further includes a camera assembly used to capture images of a surrounding area of a vehicle, the camera assembly includes a camera body, and the camera body secures the conditioning element with the plurality of fins extending from the back of the camera body.
