A spectroscopic camera includes: a variable-wavelength interference filter; an image pickup element receiving light outputted from the variable-wavelength interference filter; a first circuit board where the variable-wavelength interference filter is provided; a second circuit board where the image pickup element is provided; a casing accommodating the first circuit board and the second circuit board; a first connector mounted at the first circuit board and provided with a first FG terminal electrically coupled to an external device; and a second connector mounted at the second circuit board and provided with a second FG terminal electrically coupled to the external device. The casing is electrically coupled to the first FG terminal of the first connector and the second FG terminal of the second connector without going through the first circuit board and the second circuit board, respectively.

Electronic apparatus and spectroscopic camera

An optical filter device includes a wavelength variable interference filter that includes a pair of reflective films which face each other, and a fixed substrate in which one of the pair of reflective films is provided; a base to which the fixed substrate is fixed; and a fixing member which fixes one place on the fixed substrate to the base, a surface which is on other place of the one place of the substrate and the base are disposed with a gap therebetween.

Optical filter device, optical module, and electronic apparatus

An optical module includes: a filter holding member to which an interference filter having a pair of mirrors facing each other is fixed; a base to which the filter holding member is fixed; and a first fixing member which fixes the filter holding member to the base. In the optical module, k&#x3c;m&#x3c9;/2 is satisfied, where k is a spring constant of the first fixing member, &#x3c9; is a frequency of vibration generated in the base, and m is a total mass of the interference filter and the filter holding member.
