Camera 4000 Mono

Indicates the type or construction of the chip.

Specifies the edge length of the mostly square pixels that make up a camera sensor.

Electrons are released in each pixel, whether they are illuminated by photons or not. Each CCD chip generates a certain amount of thermal energy and thus an amplifying signal. As soon as the image of the CCD chip is read out, you will see a noisy image.

The maximum exposure time in minutes that is possible with this camera.

Each CCD camera tends to produce image noise, an interference that appears as a kind of unattractive grain on the image. The issue is especially important with longer exposure times. In addition to the general noise, there is also a noise generated by the process of reading the image: the read noise.

For long exposure times, many CCD cameras are cooled to reduce thermal noise and achieve higher image quality. CCD cameras are grouped into three categories:
- no cooling
- passive cooling via cooling fins
- active cooling (e.g. using a fan and Peltier element)

Colour cameras produce quick results, monochrome cameras capture more detail.

The full well capacity indicates how many electrons a single pixel can hold. The larger the chip, the more sensitive it is to light, and the more electrons it can absorb. But what does that mean? The noise is reduced at a large full well capacity and the ability to reproduce very bright and dark objects simultaneously increases.

The bit depth is also referred to as the dynamic range of a chip. The number of bits in a picture also determines how many different shades of grey can be displayed. The depth of the image information depends directly on it. In an image taken with 1 bit depth, you will only see black and white dots. In this case, you can hardly call it a picture. Many details that the naked eye can discern are missing. 16 bits means the presentation of more than 65.000 shades of grey.

Specifies the total number of pixels. With this handy value you can compare the resolutions of different cameras.
