Abstract
The utility model discloses an infrared coated lens. The infrared coated lens is characterized by comprising a lens (4) and coatings at the two sides of the lens (4). The lens (4) is an ED glass, and the coatings are formed by composting an outer layer (1), an interlayer (2) and an inner layer (3). The outer layer (1) and the inner layer (3) are titanium dioxide films having low refractive indexes, and the interlayer (2) is a germanium film having a high refractive index. The infrared coated lens provided by the utility model has the characteristics of being low in chromatic aberration and long in service life, enabling the coatings to be combined firmly, being suitable for various natural environments, and enabling the transmittance of a specific infrared wavelength band to reach 100% by setting the thicknesses of the coatings.
Description
Technical field
The utility model relates to a kind of optical field eyeglass, particularly relates to a kind of infrared plated film lens.
Background technology
Along with the development of forestry development, forest land area, forestry accumulation increase year by year, and forest fire protection task is day by day arduous.At present domestic forest fire protection measure is respectively: ground patrols that monitor, observation tower, aviation is patrolled and satellite remote sensing.Then above four kinds of surveillance and control measures exist respectively and have high input, landform limitation, invest shortcoming high and that susceptibility is not high.The infra-red thermal imaging system of promoting at present, by receiving the infrared ray of object transmitting, through a series of processing, heat picture that can formation surface, the temperature survey at the line correlation position of going forward side by side.The infrared emanation of its passive receive target, irrelevant with weather conditions, no matter all can normally work day and night, under the harsh climate conditions such as rain, snow mist, has equally good observing effect, and this system installation and maintenance maintenance is simultaneously easily.Feature based on infra-red thermal imaging system, it is substituting other forest fire protection surveillance and control measures.As infrared thermography foremost in this system, by using infrared plated film lens can improve the imaging effect of infrared thermography, along with the development of molding and coating technique, more excellent eyeglass and plated film are combined into one of main path improving the outer thermal imaging system performance of heat.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of infrared plated film lens, and this infrared composite membrane eyeglass has low dispersion, plated film and is combined the features such as the damp and hot and reform of nature corrosion environment of firm, resistance to height with eyeglass.
For achieving the above object, a kind of infrared plated film lens that the utility model provides solves above technical matters by the following technical programs:
A kind of infrared plated film lens, comprise eyeglass and the identical plated film in described eyeglass both sides, described eyeglass is ED glass, and plated film is composited by three layers of skins, middle layer, internal layer, described skin and internal layer are the titanium deoxid film of low-refraction, the germanium film that middle layer is high index of refraction.The optical thickness summation of described outer titanium deoxid film and internal layer titanium deoxid film is within the scope of 78.1-4166.7nm, the optical thickness of described middle layer germanium film is in 43.4-2314.8nm, this kind of thickness setting, can be according to infrared thermography according to concrete environment for use with near infrared, middle infrared wavelength monitoring range, select each optimum tunic thickness, the infrared light that reaches specific wavelength section sees through the transmitance nearly 100% of plated film.
ED glass mirror, than traditional glass, resin lens, has the feature of Extra-low Dispersion.Particularly, in the utilization of long focal length lens, make actual the focusing on same plane of light of different wave length, realize the high definition imaging of imager; The ceramic membrane that the titanium deoxid film that plated film inside and outside layer in eyeglass both sides is used is low-refraction adopts fluoride film, alkaline metal film and semiconductive thin film than current this area, have adhesion strong, be difficult for chemical change and nontoxic feature.Ectonexine is titanium deoxid film layer, middle layer is the plated film of germanium film layer, for one deck low-refraction, one deck high index of refraction, the optic film structure of one deck low-refraction again, by adjusting the optical thickness of each tunic, can make the transmitance of infrared light of specific wavelength section nearly 100%, thereby meet specific wavelength section, monitor needs.
Side along described eyeglass is also provided with at least one ring groove.The ring groove arranging is used for installing elastic washer, utilizes the screen resilience of elastic washer to be convenient to realize good fix of eyeglass in lens frame; Meanwhile, the elastic washer after installation under compression deformation state, can realize the sealing of eyeglass and lens frame junction, prevents that moisture or other impurity from entering into lens frame inside.
On the surface of described ring groove, be also provided with at least one groove.
The utility model when mounted, can be by arranging the projection corresponding with groove on elastic washer, and making can be relative fixing between elastic washer and eyeglass after installation.
The intersection of the side of described eyeglass and eyeglass both sides is rounded corner.
The setting of rounded corner is intended to prevent that eyeglass is when being subject to clashing into, and between eyeglass and lens frame, stressed place stress is concentrated and destroyed.
The utlity model has following beneficial effect:
A kind of infrared plated film lens that the utility model provides, has low aberration, plated film in conjunction with firmly, adapt to various physical environments, physical life long, for the thickness of setting each layer of plated film, specific infrared light wavelength section transmitance is approached to 100% feature.
