Lens and Field of View

Hi !

I have a Pyrometric sensor and I want to change his field of view.

I want to do a non-contact termomiter and I need to have a tightened filed of view.

In the datasheet of sensor there is only the graphics of field of view.

Moreover my sensor has an internal reflector, but I don't know what it is.

How I can choose the right lens for do this ?

Thanks
 

Re: Lens and Field of View

To narrow filed of view you need a plano convex lens PCX (one side flat). You probably need less than 5° field of view.
To calculate the right lens you will need to know what is the field of wiev of this sensor without a lens..
Some selection of lenses you may find in:

Re: Lens and Field of View

Ok I have a plano convex lens and I tried to put in front of my sensor.

I putted my sensor on the focus of lens but it doesn't work, the field of view remains quite the same.

How will you put the lens ?

I would revers the sequence: put the object in FOCUS and the sensor on the other side of the lens .. and try again ..

What material is your lens made of? I doubt a glass has any use here.
