1570 nm military infrared bandpass filter1570 nm military infrared bandpass filter, mainly used in laser range finder, missile bomb guide head.1. product introductionThe high-performance narrow-band infrared filter produced by Kingki Optical has a spectral coverage of 780nm~5000nm. The product has long life, no drift, high transmittance, deep cutoff, high quality and low price.(1570nm military infrared bandpass filter)2. the military infrared filter parameter curve: (You can fill in the demand table at the end of the text to tell us that you want the product)Transmittance curve, BP1570, FWHM3. Application:1570nm military infrared bandpass filter, mainly used in laser range finder, missile bomb guide head. The laser semi-active homing guide is configured to separate the attacking warhead from the "laser target indicator" used to direct the target. When attacking, first use the laser target indicator to illuminate the laser beam from the ground or in the air. The "seeker" at the front end of the aggressive warhead that launches or launches captures the laser light diffused back from the target surface, and controls and guides. The warhead strikes the target until it hits the target and blows up the target. Because the directionality of the laser beam is excellent and the divergence angle is extremely small, the laser-guided weapon has a very high hit accuracy, which can be said where to play.4. Company's strengthJinji Optics' long-term production of 1570nm high-end military infrared filters is the main manufacturer of laser ranging and laser-guided filters in China.Kingki has long been responsible for the research and production of military optical coatings. The chief engineer has more than 40 years of military optical coating experience, 33 national authorized patents, and nine scientific and technological achievements won the People's Republic of China Science and Technology Progress Award.Kingki has a high-end factory building of 4,000 square meters, 13 sets of advanced coating machines and complete test equipment, with the ability to mass produce high-end optical filters.Kingki's wide range of products, excellent performance, quality and cheap, prompt delivery.5.

It simply means that the substrate has an index sufficiently higher than the available thin-film materials to enable the design of high-performance antireflection coatings consisting entirely, or almost entirely, of layers with indices lower than that of the substrate. These high-index substrates are principally of use in the infrared. Semiconductors, such as germanium, with an index of around 4.0, giving a reflection loss of around 36% per surface, and silicon, with index around 3.5 and reflection loss of 31%, are common, and it would be completely impossible to use them in the vast majority of applications without some form of antireflection coat- ing. For many purposes, the reduction of a 30% reflection loss to one of a few percent would be considered adequate. It is only in a limited number of applications where the reflection loss must be reduced to less than 1%
