It's very difficult information to find in my experience. Your best bet would be to try to find out the exact sensor model in the mouse and look that up, rather than the mouse itself, though I'm not sure if specs for mouse sensors are even publicly available.spacediver wrote:is there a surefire way to figure out the native dpi of a mouse/sensor?

get a microscope and image the pixel arrayspacediver wrote:is there a surefire way to figure out the native dpi of a mouse/sensor?
invert the spacing between the pixels and multiply (or divide... not sure, too lazy to think atm) by the lens magnification ratio which is usually provided in the datasheet (e.g. http://www.pixart.com.tw/upload/ADNS-21 ... 110417.pdf )

Re: Inherent click delay found in mice.
interesting, might be able to do that with the macro setup.
Re: Inherent click delay found in mice.
yup, and if your depth of field is narrow enough you can probably get very accurate measurements ( if you calibrate against something else first)
im not sure how to crack open the sensor chips though
but you can see some pictures here

Re: Inherent click delay found in mice.
yes, I have my ronchi ruling for calibration and it works perfectly.
Not sure if I want to risk anything by cracking open my sensor. I have a very fragile setup - old deathadder 3.5 sensor frankensteined to a logitech wingman mouse. It's a one of a kind and I'll be devastated if something happens to it :p
Maybe I can hunt down a broken mouse that has the same sensor (Avago S3888).

or just ask skylit on ocn :p
Re: Inherent click delay found in mice.
On most sensor casings I have seen the top is just mounted on and can be removed relatively easily.
With microscoping the problem I mostly ran into is getting proper lightning from above, but there's specialised gear for that naturally.
In that pcgamer logitech interview they revealed a common actual surface coverage of modern arrays is about 30 micrometer a pixel.

That would be about 800 DPI which is extremely common.stirner wrote:On most sensor casings I have seen the top is just mounted on and can be removed relatively easily.
