Description
Technical field
The present invention relates to imaging device filtering apparatus technical field, in particular to a kind of new structural linear double optical filterings
Piece switch.
Background technique
Double optical-filter switchers (i.e. IR-CUT) in monitoring camera, are a kind of switching device of optical fiber, on daytime
When optical filter is switched to infrared fileter, filter out infrared ray, image avoided to be distorted, and be switched to full spectral filtering at night
Piece increases the brightness of image of night camera head.
Traditional linear double optical-filter switchers, by stainless steel cover board, optical filter box, magnetic core swing arm unit, U iron,
Coil block, pedestal and wire assembly 7 are constituted.Wherein stainless steel cover board is because double optical-filter switchers itself require as far as possible not
It is reflective, it is therefore necessary to which that surface is applied as by matt black by electrophoresis；And it is mutually fastened by 5 buckles with pedestal.Optical filter
Component is fixed in mylar film (PET film) by full spectral filter and infrared light filter disc by viscose glue mode.Since product makes
Particularity need to use epoxy resin glue sticking, but because of mylar film surface tension problem itself, be easy to cause glue in wheat
Pulling-on piece diffusion into the surface, so that after glue curing, some glue is since cause cannot for curing agent diffusion not synchronous with bonding agent
Solidification is easy to produce mylar film and the adhesion of stainless steel cover board, causes product failure.
In addition, double optical-filter switchers use since it is desired that being inserted into card slot, therefore its thickness has rigid requirement, total thickness
Degree requires to be 1.8mm.Stainless steel cover plate thickness 0.2mm has reinforcing rib, height 0.25mm, filter thickness above cover board
0.21mm, mylar film thickness 0.19mm have the slide rail for reducing frictional force, height 0.2mm, the thickness of pedestal on pedestal
0.6mm.So through calculating, spatial margin be 1.8mm-0.2mm-0.25mm-0.21mm-0.19mm-0.2mm-0.6mm=
The surplus of 0.15mm, space are smaller.If by stainless steel cover board be changed to injection molding cover board, thickness necessarily more than 0.2mm, and
And since cover board also needs to fasten with pedestal, fastening part is also required to biggish thickness requirement, and the thickness of such words cover board will
It can be considerably beyond 0.2mm.And if mylar film is replaced with injection molding support, backing thickness equally can also substantially exceed 0.19mm
Thickness, will will lead in this way spatial margin deficiency.
