Abstract
The utility model is related to the not light leak connection area of moveable optical element, specially a kind of infrared lens with ring-shaped shield lid.A kind of infrared lens with ring-shaped shield lid, including shell (1) and germanite glass window (2), it is characterized in that：Also include infrared lens (3) and cover (4), one side of shell (1) is provided with fenestra (11), germanite glass window (2) is rotationally provided with fenestra (11), infrared lens (3) are movably disposed in shell (1), (4) are covered to be rotatably arranged in shell (1), infrared lens (3) are just to fenestra (11), alignd so that both pieces together a complete circle with the two ends for covering (4) respectively at the two ends of germanite glass window (2), cover the central angle of the central angle more than germanite glass window (2) of (4).The utility model simple structure, it is easy to use, reduce use cost.
Description
Technical field
The utility model is related to the not light leak connection area of moveable optical element, specially a kind of to carry ring-shaped shield
The infrared lens of lid.
Background technology
The response wave band of medical infrared thermal imaging system is at 8 μm~14 μm, and visible ray is not in same wave band, therefore, red
The glass window added before outer camera lens must select the germanium window for having response wave band at 8 μm~14 μm, but the price of glass is high
It is high, which limits the further genralrlization application of thermal infrared imager.
Utility model content
In order to overcome the defect of prior art, there is provided a kind of simple structure, infrared spy that is easy to use, reducing use cost
Instrument is surveyed, the utility model discloses a kind of infrared lens with ring-shaped shield lid.
The utility model reaches goal of the invention by following technical solution：
A kind of infrared lens with ring-shaped shield lid, including shell and germanite glass window, it is characterized in that：Also include infrared mirror
Head and covering, a side of shell are provided with fenestra, fenestra and are rotationally provided with germanite glass window, the cross section of germanite glass window
It is circular arc, infrared lens are movably disposed in shell, the central angle of infrared lens is covered more than the central angle corresponding to fenestra
It is rotatably arranged in shell, just to fenestra, the cross section of covering is circular arc to infrared lens, germanite glass window and covers both
The center of circle overlaps and radius is equal, and the two ends of germanite glass window are alignd with the two ends for covering respectively so that both pieces together one completely
Circle, the central angle of the central angle of covering more than germanite glass window.
The described infrared lens with ring-shaped shield lid, it is characterized in that：The central angle of germanite glass window is not more than 60 °.
When the utility model is used, when needing infrared lens to shoot, turning cover makes germanite glass window laminating fenestra, infrared
Camera lens can shoot infrared image by germanite glass window；When infrared lens are moved without implementing to shoot in casing, now rotate
Covering makes covering laminating fenestra and germanite glass window is removed fenestra, so when in infrared lens pitching moving process, covering will be red
The viewfinder range closing of outer camera lens, is similar to the white of the eye of eyeball by light barrier, coordinates casing to realize closed effect.This practicality is new
Type in the case where whole casing sealing is ensured, can reduce the area of germanite glass window, so that reduces cost.
The beneficial effects of the utility model are：Simple structure, it is easy to use, reduce use cost.
Brief description of the drawings
Fig. 1 is the structural representation of casing in the utility model；
Fig. 2 is structural representation of the present utility model.
Specific embodiment
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of infrared lens with ring-shaped shield lid, including shell 1, germanite glass window 2, infrared lens 3 and covering 4, such as
Shown in Fig. 1 and Fig. 2, concrete structure is：
A kind of infrared lens with ring-shaped shield lid, including shell 1 and germanite glass window 2, it is characterized in that：Also include infrared
Camera lens 3 and covering 4, a side of shell 1 are provided with fenestra 11, fenestra 11 and are rotationally provided with germanite glass window 2, germanite glass
The cross section of window 2 is circular arc, and infrared lens 3 are movably disposed in shell 1, and the central angle of infrared lens 3 is more than the institute of fenestra 11
Corresponding central angle, covers 4 and is rotatably arranged in shell 1, and just to fenestra 11, it is circle to cover 4 cross section to infrared lens 3
Arc, and the center of circle covered both 4 overlaps and radius is equal for germanite glass window 2, the two ends of germanite glass window 2 respectively with cover 4 two
End is alignd so that both pieces together a complete circle, the central angle of the central angle more than germanite glass window 2 of covering 4.
The central angle of germanite glass window 2 is not more than 60 °, in the present embodiment：The central angle of germanite glass window 2 takes 60 °, covers 4
Central angle takes 300 °.
When the present embodiment is used, when needing infrared lens 3 to shoot, turning cover 4 makes the laminating fenestra 11 of germanite glass window 2,
Infrared lens 3 can shoot infrared image by germanite glass window 2；When infrared lens 3 are moved without implementing to shoot in casing 1,
Now turning cover 4 makes the laminating fenestra 11 of covering 4 and germanite glass window 2 is removed fenestra 11, so when the pitching of infrared lens 3 is moved
During, cover 4 and close the viewfinder range of infrared lens 3, the white of the eye of eyeball is similar to by light barrier, coordinate casing 1 to realize
Closed effect.
Claims (2)
