OPTICAL MODULE AND ELECTRONIC APPARATUS

摘要

An optical module includes a circuit substrate that has a concave portion and a flat surface, an optical sensor that is disposed inside a space, and an optical filter device that has a base which accommodates a variable wavelength interference filter and has a light-through hole through which light emitted from the variable wavelength interference filter passes and a first glass member which is disposed in the light-through hole. The first glass member is positioned inside the space. The base is bonded to the flat surface. The distance between the first glass member and the optical sensor is set to a distance at which light emitted from the variable wavelength interference filter does not interfere between the first glass member and the optical sensor.

1. An optical module comprising:
a substrate that includes a flat surface and a hole in the flat surface; a light-receiving element disposed within a space defined by the hole and a plane of the flat surface; and an optical filter device that includes:
a casing which accommodates an interference filter and includes a light-through hole through which light emitted from the interference filter passes; anda translucent member disposed in the light-through hole, wherein the translucent member is positioned inside the space, the casing is bonded to the flat surface, and a distance between the translucent member and the light-receiving element is set to a distance at which light emitted from the interference filter does not interfere between the translucent member and the light-receiving element.
