Abstract
A kind of infrared optical window is provided in the utility model, belongs to infrared imagery technique field.The infrared optical window includes substrate, and the top and bottom of the substrate plate and are formed with optical film, and the surrounding of top optical film is coated with metal film, is coated with layer protecting film on the bottom optical film.While infrared optical window transmitance needed for meeting infrared imaging, the antiwear property and tolerance in the presence of a harsh environment of the window are improved.
Description
Technical field
The utility model relates to infrared imagery technique field, in particular to a kind of infrared optical window.
Background technique
Infrared optical window is indispensable component in non-refrigerated infrared focal plane probe system, is mainly used in heat
Imaging field, it is required that certain stray lights are filtered while being infrared transmittivity, it is clear to reach imaging effect.It is answered certain
With field, because the particles such as raindrop, the sand grains of most of the time in field work, environment can produce window surface film layer
Raw bigger impact, surface needs to be coated with protective film to improve its anti-weathering, the ability of sand cutting.
Summary of the invention
The purpose of this utility model is to provide a kind of infrared optical window, the transmitance needed for meeting infrared imaging
Meanwhile solving the problems, such as the antiwear property deficiency of existing window and poor resistance in the presence of a harsh environment.
In order to solve the above technical problems, the utility model provides a kind of infrared optical window, it is burnt for uncooled ir
Planar detector, the infrared optical window include substrate, and the top and bottom of the substrate plate and are formed with optical film, top light
The surrounding for learning film is coated with metal film, is coated with layer protecting film on the bottom optical film.
Optionally, the material of the substrate is germanium, silicon, zinc selenide or quartz glass.
Optionally, the material of the optical film is one or more of Ge, ZnS, CaF, YbF3, SiO.
Optionally, the metal film is one or more of Ti, Ni, Pt, Cr, Au.
Optionally, the protective film is DLC film, with a thickness of 10 ~ 500nm.
Optionally, the form and dimension of the DLC film is according to detector chip size and reconfigurable.
In a kind of infrared optical window provided by the utility model, including substrate, the top and bottom of the substrate are equal
Plating is formed with optical film, and the surrounding of top optical film is coated with metal film, is coated with layer protecting film on the bottom optical film.This is infrared
While optical window transmitance needed for meeting infrared imaging, the antiwear property of the window is improved and in adverse circumstances
Under tolerance.
Detailed description of the invention
Fig. 1 is the infrared optical window structural schematic diagram that the present embodiment one provides.
Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of infrared optical window make further it is detailed
It describes in detail bright.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached
Figure is all made of very simplified form and using non-accurate ratio, only to convenient, lucidly aid illustration is originally practical new
The purpose of type embodiment.
Embodiment one
The utility model provides a kind of infrared optical window, is used for non-refrigerated infrared focal plane probe, specific structure
As shown in Figure 1.The infrared optical window includes substrate 1, and the material of the substrate 1 is germanium, silicon, zinc selenide or quartz glass.
The top of the substrate 1 is coated with optical film 2a, and bottom is coated with optical film 2b, the material of top optical film 2a and bottom optical film 2b
For one or more of Ge, ZnS, CaF, YbF3, SiO.The surrounding of top optical film 2a is coated with metal film 3, the metal film 3
For one or more of Ti, Ni, Pt, Cr, Au.Layer protecting film 4, the protective film 4 are coated on the bottom optical film 2b
For DLC film, with a thickness of 10 ~ 500nm.The form and dimension of the DLC film according to detector chip size and
Reconfigurable.While infrared optical window transmitance needed for meeting infrared imaging that the present embodiment one provides, in bottom
On optical film plus coating diamond-like film, the antiwear property and tolerance in the presence of a harsh environment of the window are improved
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Fixed, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content belong to right and want
Seek the protection scope of book.
