If the letters of a book, or any minute object, be viewed through a lesser segment of a sphere of glass or crystal, whose plane base is laid upon them, they will appear far better and larger.

The magnifying glass is situated amongst a host of other magnification technologies. The majority of these technologies share many optical principles and purposes; specifically, to image objects at an increased resolution and magnification than is possible with the human eye through exploitation of the properties of light. The distinguishing feature of the magnifying glass is its structure—a bi-convex lens (one that is convex on both sides) situated in a frame and attached to a handle. The lens may be constructed of glass or plastic, and the handle of materials such as wood, plastic, and metal. This produces an image of the object behind the lens. Although the magnifying glass has been altered over the years with the introduction of new materials, the basic structure remains the identifying feature of the magnifying glass.

I purchased one of the ZWO ASI178MM-Cool cameras today at OPT in California, so the cameras are now available in the U.S.

At least for some time bigger pixels will be in their offer as very small pixels aren't needed/are bad for surveillance and other low light conditions. There is also GPixel or CMOSIS that have some bigger pixels. e2v has few mass market CMOS sensors, but all of those companies doesn't seems to be interested in aggressive development of such mass market sensors.

Despite long term maintenance of the magnifying glass’s physicality, new structures for the magnifying glass have been developed as the purpose and scope of the magnifying glass has changed. Virtual magnifying glasses have become a necessity, and software such as Zoomify allows the close examination of digital images. Historically, the magnifying glass has seen vocational use in textiles, such as thread counters. Today, jewelers and dentists use forms of magnifying glasses that have become more technologically advanced over the years. Mass production of plastic magnifiers has allowed for wide-spread utilization in science classrooms. Lighted magnifiers, page magnifiers, clip magnifiers, in addition to many other forms of magnification, have adapted the structure of the magnifying glass to specific purposes.

Yes, the only monochrome surveillance camera that is listed in that table is the IMX136LLJ (2.8um pixels and 1944H × 1224V).

The longevity and consistency of the structure of the magnifying glass over the years has allowed the magnifying glass to become iconic. This aesthetic value relies on "the absolute mechanical perfection of the design” according to Latour (301), a theory echoed by Leroi-Gourhan. Although on a much smaller time scale, a parallel can be drawn between the ax in Leroi-Gourhan's 'Gesture and Speech' and the magnifying glass; the ax obtained its ideal form early in its development, and therefore its structure remained relatively constant over time. The magnifying glass also developed early on as a practical method of magnification and its consistency of form has contributed to its value as a symbol. A tool whose form is ideally related to its function obtains an aesthetic value, a trend readily observable in the magnifying glass whose form has provided a basis for many other optical tools (see Improved Magnifying Capabilities). Magnifying glasses became symbols of intellect and connoisseurship, as is evident in art of the eighteenth century which often depicts magnifying glasses in order to convey knowledge and intellect. Today, virtual images of magnifying glasses are utilized by search engines, indicative of a close examination of the internet, and in magnification tools utilized in imaging software.

Sony imx178release date

I can find no reference to a monochrome version of IXM178 on the Sony.net websites. Thus, has this version of the sensor actually been released or even documented by Sony?

Sam, can you chip in? Is the IMX178mm really so new? From the Sony site, the imx178 color chip was introduced in 2013.

Sometimes it's harder to make uniform mono sensor. Then doing Bayer pattern may ease hiding that problem. That could be true for old sensors but nowadays production quantity dictate prices. If it's really mass made sensor then it will be relatively cheap. Low quantity sensor will be more expensive.

So, it seems like a monochrome version of the IMX178 would be unique in that it would have the Starvis designation and a rolling shutter and be marketed as a surveillance camera.

Someone on another forum said that they had the spec sheet for the mono version of the IMX178, but that source said that Sony has NOT introduced this sensor as yet, perhaps the announcement will come sometime this month.

Can anyone point to any independent confirmation on the internet that shows that the monochrome version of this sensor actually exists?

I'm beginning to wonder whether the ASI178MM is just the color IXM178 that has had its Bayer filter removed by third-parties. If that is true then these cameras should probably be marketed as modified sensors, not as a new product that has come directly from Sony.
