Sensor data

When you are selecting a camera it’s always prudent to find out what sensor the manufacturer is using. Then take a look at the quantum efficiency graph. This shows the relative sensitivity of the sensor to wavelengths of incident light and may influence your choice of illumination. Not all sensors are the same!

The problem though is that while some camera vendors make this information available – AVT is one such – it can be hard to find what you need. And for some reason this seems particularly true when Sony sensors such as the ICX625 are involved.

But I have good news! (Well, a small portion of good news anyway.) Point Grey have some quantum efficiency data in the knowledge base area of their website. This covers Sony CMOS and CCD sensors as well as CMOS sensors from Aptina and Cmosis. Take a look! It’s free!
