    Abstract: Provided are a composite photosensitive element and a method for preparing a composite photosensitive element, and the composite photosensitive element includes a photosensitive element and a near-infrared absorption layer pasted on the photosensitive element, wherein the near-infrared absorption layer includes a copper complex, and the copper complex is formed from a copper compound providing copper ions, phosphoric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the near-infrared absorption layer for the incident light wavelength from 930-950 nm is greater than 4. The present disclosure forms a filtering film directly on the photosensitive element instead of using a traditional filter assembly to reduce the size of the assembled product. The filtering film can be further processed and shaped to have functions of micro-lens.

    Abstract: Provided is a microsphere including a glass sphere core. The glass sphere core includes a first nuclide, a second nuclide and a diffusion region extending inwardly from an outer surface of the glass sphere core, with the second nuclide distributed in the diffusion region. The first nuclide and the second nuclide become radioactive after being activated by neutrons to produce radiations including β-rays or γ-rays, or simultaneously β-rays and γ-rays. A preparation method of a microsphere is also provided.

    Abstract: A Faraday rotator is formed of a class of semiconductor materials of low free carrier density wherein, in the presence of a suitable magnetic field, interband transition Faraday rotation is opposite in sign from free carrier effect Faraday rotation and interband transition Faraday rotation predominates over free carrier effect Faraday rotation such that net Faraday rotation can remain nearly unchanged over broad IR spectral regions where the short wavelength limit is typically near the bandgap absorption. Thus, the class of semiconductors meeting these conditions can function as high performance broadband optical isolators in the infrared. Suitable materials include InAs of suitable purity.

    Abstract: A fibre-optic imaging block for producing a high contrast, visible image of an object. A common light entry/exit face of the block is illuminated with light which is totally internally reflected interior of the individual block fibres toward an opposing partially cylindrical angular objective surface. When the object is placed on the objective surface of the block, a high contrast visible image is produced over the entire imaging angle defined by the sector angle of the objective surface. A complementary correction slug eliminates compound distortions introduced by the objective surface configuration. In an alternate embodiment of the imaging block, field distortions are eliminated by forming the individual fibre ends tangent to the objective surface, and a special correction slug is provided for optionally eliminating inclined plane and line curvature distortions. A finger printing system employs the imaging block in combination with a flash lamp and means for viewing the finger print image before recording on film.

    Abstract: An optical filter and a matching composite layer thereof are provided. The matching composite layer includes a plurality of first refraction layers, a plurality of second refraction layers, and a plurality of third refraction layers. A refractive index of the second refraction layer is greater than that of the first refraction layer, and is less than that of the third refraction layer. Any two of the second refraction layers provided with one of the first refraction layers sandwiched there-between are sandwiched between two of the third refraction layers so as to be jointly defined as a bidirectional incremental module. A number of the bidirectional incremental module included in the matching composite layer is at least M, where M is a positive integer greater than three. The M number of the bidirectional incremental modules are stacked and connected with each other.
