Help with lens setup for long working distance

Hi
I have a lens config using Optem Fusion gear. It gets me final field of view on a 2/3" sensor about 3 x 2mm. The working distance is 30-40mm depending on the zoom setting.
But I really need to push the working distance out to around 200mm. Below are links to the current setup.
Is there a component I can add to extend the working distance to 200mm without changing the final FOV?

Thanks you for any assistance

Hi mattnz,
Welcome to the Digikey forum. Looking at the datasheet page 16, chart 2B it appears if you switch to a 1" FOV and add a lower lens, part 35-00-09-000 you should be able to increase the working distance up to 290mm.

Look at the part number and data sheet to see if you see the same thing as me, (it’s a bit confusing). Also, read page 3, note number 2 of the data sheet, this is where I found the working distance information.

Hi
Thanks for the input. Yes, I think I see the part you’re referring to, I’ve attached a cropped chart.
Can you confirm these parts will get me the 190mm WD and a MaxMag 2.3x3.0mm on a 2/3" sensor?
Thanks so much for the assist.
