The invention relates to a photographing device whose bulk is intended to be reduced. According to the invention, a permanent division of the object field observed by the device is associated with a catadioptric configuration.

Compact photographing device

The invention pertains to a process and to a device for positioning an optical component between two optical fibers furnished at their end with lenses comprising: drilling a support in such a way as to fix therein a capillary tube whose inside diameter is designed to slip an optical fiber thereinto, fixing the capillary tube in the drilling of the support, making a blind cut of the support and of the capillary tube, in such a way as to separate the capillary tube into two parts, a first plane face of the cut being perpendicular to a longitudinal axis of the capillary tube, positioning the component on the first plane face, positioning an optical fiber in each of the parts. The device comprises a support through which is fixed a capillary tube, the support comprising a cut so as to separate the capillary tube into two parts. The cut comprises a first plane face perpendicular to a longitudinal axis of the capillary tube. The component is positioned on the first plane face.

Process and device for positioning an optical component between two optical fibres

The invention relates to wavelength-selective optical filters for allowing light of a narrow optical spectral band, centered around a wavelength (&#x3bb;) to pass through them, while reflecting the wavelengths lying outside this band. According to the invention, the transfer function (T(&#x3bb;)) of the component is defined by multiplying two transfer functions of spectrally offset Fabry-Perot filters.
