摘要:
A photoelectric conversion device using an amorphous material composed mainly of tetrahedral elements including at least an element of hydrogen and halogens as semiconductor material is disclosed. When a strong electric field is applied to a layer formed by using this amorphous semiconductor, a charge multiplication effect is produced mainly in the interior of the amorphous semiconductor and thus it is possible to obtain a thermally stable photoelectric conversion device having a high sensitivity while keeping a good photoresponse.
摘要:
A target of an image pickup tube is formed by laminating at least a transparent conductive film (2), an amorphous layer (4) consisting essentially of silicon containing hydrogen, and an amorphous layer (5) consisting essentially of selenium in the above order on a light-transmitting substrate (l). The selenium layer (5) prevents deterioration of the performance of the silicon layer (4) with time, while not affecting the useful properties of the silicon layer (4).
摘要:
The present invention provides an ND filter and a television camera which can obtain a video with favorable quality which does not give sense of discomfort to viewers, and a manufacturing method of the ND filter. In an ND filter (10) of the present invention, a first region (34) with a light transmittance of about 100% and a second region (36) with a light transmittance continuously changing stepwise are continuously formed in a circumferential direction of a transparent glass board (32) formed in a disk shape. Therefore, image light transmits through all regions of the transparent glass board (32). Thereby, at the time of operation of light amount regulation, a region through which the image light does not transmit does not traverse a passage area (50) of the image light, and therefore, a screen does not become dark momentarily at the time of operation of light amount regulation. Therefore, by using the ND filter (10), a video with favorable quality without giving sense of discomfort to viewers can be obtained.
