An underwater observation device is proposed. The underwater observation device includes a case body having an inner space. The case body includes a first filtering portion, a first transparent portion, and a second transparent portion. The first filtering portion is configured to filter impurities in the water entering the case body. The first transparent portion and the second transparent portion are adjacent to the first filtering portion and are located on two opposite sides of the case body respectively. The first transparent portion and the second transparent portion are configured for a user to observe at least one object through the case body.

A camera cover is provided. The camera cover has a coating formed on a surface of the camera cover. The coating contains a urethane acrylate resin. The camera cover has a dome shape and is designed to protect an image capturing unit. A Berkovich hardness at an indenter penetration depth of 100 to 300 nm on a surface of the coating is at least 0.4 GPa.

A sensor module according to an embodiment of the present technology includes a sensor element, a first case, a second case, and an intermediate layer. The first case includes an opening end and accommodates therein the sensor element. The second case includes a joining surface welded to the opening end. The intermediate layer is reflective of light, and is formed along an outer peripheral edge of a region, in the opening end, in which the opening end faces the joining surface.

A vehicular camera includes a printed circuit board (PCB) having an imager disposed thereat. A lens barrel accommodates a lens and includes a first end and a second end and an annular flange between the first end and the second end. A front camera housing includes a first portion having a first material having a first coefficient of thermal expansion (CTE) and a second portion having a second material having a second CTE, with the first CTE being higher than the second CTE. A rear camera housing and the second portion of the front camera housing are joined to encase the PCB within a cavity formed by joining the front camera housing and the rear camera housing.
