Following up on the previous post, I thought it would be worthwhile compiling the pixel sizes and numbers of some existing cameras:
|Sensor||Dimensions (mm)||Pixel Size (micron)||Megapixels||Examples|
|Sony ICX285||8.98 x 6.71||6.45||1.45||Photometrics Coolsnap HQ2, Andor Clara, many others|
|Sony ICX674||8.8 x 6.6||4.54||2.83||Photometrics Coolsnap Myo, Raptor Photonics Kingfisher V|
|Sony ICX694||12.49 x 9.99||4.54||6.05||Raptor Photonics Kingfisher V|
|Fairchild sCMOS||16.6 x 14.0||6.5||5.53||Andor Neo and Zyla, PCO Edge|
|Flash 4.0||13.3 x 13.3||6.5||4.19||Hamamatsu Flash 4.0|
This is a very truncated listing of the cameras out there, and basically only includes cameras I’m directly familiar with. I’m also excluding EMCCDs and only including cameras 1.4 MP or larger. The vendors mentioned here all many other camera models and there are a number of other vendors out there, some of which make pretty interesting cameras.
Artemis CCD, a company I came across while doing research for this post, appears to make some pretty nice CCDs. I’d be curious to know more about them.
For larger format CCDs there are a number of companies that target both the astronomy and the biology market. Apogee and Finger Lakes Imaging are two I’ve seen a lot. Many of their cameras use Truesense (formerly Kodak) sensors, which come in very large formats, but generally seem to have lower quantum efficiency and higher read noise.
