CCD(Charge-coupled Device) and CMOS (Complementary Metal-oxide Semiconductor). Presently, there are two main technologies that can be used for the image sensor in a camera, i.e. The signal constituted by the numbers is processed by electronic circuits inside the camera. The electrons are converted into voltage and then transformed into numbers by means of an A/D-converter. The stronger the light, the more electrons are generated.

They convert the received amount of light into a corresponding number of electrons. The image sensor consists of picture elements, also called pixels, that register the amount of light that falls on them. When an image is being captured by a network camera, light passes through the lens and falls on the image sensor. The process by which the analog information is changed to digital is called Analog to Digital conversion. All sensors are analog devices, converting photons into electrical signals. Since every Digital camera has a sensor, it is usually either a CCD or a CMOS type chip sensor. Luminous Point: White/Black spot may appear on the image because of the internal-reflection in the lens and lens tube.Geometry Distortion: Compare to the center area, image is distorted and lower resolution in the peripheral area.Light and Shade Gap: Brightness between center and peripheral area looks different even if lighting is even.Linearity: Image may look distrorted (barrel distortion) especially at the peripheral area in focus.Vignetting: Magnification, optical design error, or fundamental structural defect causes vignetting.Generally low end adapters in the market have one or more of the following problems often associated with photomicrography: The image quality, peripheral resolution and color rendering is optimum as you would expect for a high quality Japanese C” mount adapter from Meiji Techno. Our microscope adapters are designed and developed individually for each camera’s lens system and therefore it effectively eliminates vignetting and minimizes optical errors often associated with photomicrography by a consumer digital /analog camera. Meiji Techno America’s adapters depend on the quality of our Japanese lenses.

“CS” mount cameras with require part number V-5MM to be threaded on prior to installing the adapter. They are available with projection lenses of different powers allowing some control over the magnification and the field view. Any digital or video camera with a “C” mount ( 1” diameter thread) can be mounted on any Meiji Techno Trinocular microscope ( 25.2 tube ) by using these “ C”- mount attachments. Meiji Techno America allows Digital / Analog CCD and CMOS cameras to be mounted directly to a microscopes trinocular port using the proper C” mount adapter that match’s the chip size of the camera.
