Sony has a great new 1.1” Image Sensor, but what kind of lens can I use with this format? Computar MPY Series!

If you have been around industrial camera lenses for a while, you know that there are many ½” and 2/3” lenses, not as many 1” lenses, but what do you do when you have a 1.1” sensor?!   The solution?  Use the Computar MPY  12 Megapixel lenses!Contact us

If you have been following Sony’s new IMX image sensor product line, their newest sensors are based on a 3.65um pixel pitch.  However, when you scale this up to their new 12MP sensor (Sony Pregius IMX253, IMX304), the sensor size becomes 1.1” (17.6mm diagonal) format.  A 1” lens format will not cover this image circle and in turn has vignetting in your image  (Read our blog post on sensor size vs. lens size ) .

One possible solution is to use a 1” lens and vignette 5% on each side, or use a 1” lens and stop it down where the vignetting goes away.  However this is not an optimal solution.  A second solution is to use a F Mount lens, but if the camera is a C mount, you will need a C to F adapter, again less than ideal.

Fortunately there are some C mount lenses that are greater than a 1” image format.  Kowa and Schneider both have been shipping 4/3” format lenses, although these are quite expensive.  Recently, Computar has come out with a line of 1.1” format lenses SPECIFICALLY  for this sensor!

10 key things you need to know when selecting a machine vision lens

Improper selection of the correct quality and type of machine vision lens can make your camera selection useless!

In many cases, we see customers attempting to choose a low quality lens for a camera that really needs quality optics to resolve the pixel sizes. Conversely, we also see customers trying to over specify a lens, where you simply need a lens that’s “good enough”


1st Vision has a white paper to help in the lens selection and provide valuable knowledge on various topics to make the best decisions. 

 

In this comprehensive white paper, you’ll learn the following

  1. Background basics on lenses and what they really do!
  2. The science in some basic formulas to calculate MAG, focal length and angular FOV
  3. What are extension rings used for?
  4. How are lenses rated?  MTF explained
  5. The myth behind “Megapixel” lens ratings
  6. How many pixels do I really need?
  7. What is the ” f# ” of a lens
  8. What does the “lens format” mean?
  9. Comparison of lens types from security to Factory Automation (FA)
  10. How to get some practical advice!
