Abstract
An optical detecting device capable of preventing environmental pollution includes a casing, an optical detecting component and a transparent component. The casing includes a light through unit and at least one accommodating structure. The optical detecting component is disposed inside the accommodating structure. The transparent component is disposed inside the accommodating structure and located above the optical detecting component, to partly fill the accommodating structure at least and block between the light through unit and the optical detecting component.
Claims7
An optical detecting device capable of preventing environmental pollution, the optical detecting device comprising:
- a casing, having a light through hole and at least one accommodating structure, the at least one accommodating structure inside the casing being exposed to an outside environment of the casing via the light through hole;
- an optical detecting component disposed inside the at least one accommodating structure;
- and
- a transparent component disposed inside the at least one accommodating structure and spaced from the optical detecting component and the light through hole so the light through hole is unsealed, the transparent component being pre-formed and adapted to partly and incompletely fill the at least one accommodating structure and to prevent dust falling into the casing via the light through hole from dropping over the optical detecting component.
