Description
Technical field
The present invention relates to a kind of opticglass, especially relate to a kind of broadband-spectrum optical glass and preparation method thereof.
Background technology
Atmosphere is to three wave bands of light transmission rate maximum (reflection and absorb minimum): visible waveband, 3～5 microns and 8～12 microns is called atmospheric three windows traditionally.The infrared device of long-range detection or transmission all must operate at the atmospheric window wave band.Yet most at infrared window, particularly the material that has a light transmission at 8～14 mu m wavebands does not often see through at visible waveband.This makes that visible light detection means commonly used is difficult to be suitable for, and the opticinstrument that major part is operated in infrared band is discrete with the optical device that is operated in visible light wave range, be that they respectively have the complete and independent work system of a cover, thereby make the combination of infrared system and picture processing, control quite complicated.If a kind of material all has through performance (being wide spectrum transmitting material) preferably at atmospheric three communication windows and visible light wave range, it just may make, and independently infrared system and visible light are system combined, the complicacy of simplified system makes the binding ratio of infrared system and picture processing, control be easier to greatly.

2Laser window), but acidproof and alkaline poor, cost an arm and a leg and the sedimentation velocity defective has hindered its development in wide spectrum of use.Need a kind of cost performance height of exploitation in this case badly, be easy to the wide spectrum transmitting novel material of integrated technology development.Plurality of advantages such as optical glass material has easy preparation, easy-formation, composition is adjustable, easily eliminate chromatic dispersion and aberration, light transmission is good and cost is low.Yet, the patent and the document of broadband-spectrum optical glass material are less at present, wherein domestic patent CN200610024707 invention is a kind of based on Ga, Ge, Se, the full optical window chalcogenide glass material of CsI system, though seeing through, its infrared band can reach 14 μ m, but greater than 0.55 μ m, all wave band that can't really be implemented in visible waveband is high saturating in the visible waveband cutoff wavelength for it, thereby a large amount of disappearances that can cause imaging medium short wave information cause the influence to image quality.
