Hi Fraser,
Yeah i saw a few similar specification germanium coated lenses ranging from £130 to £170 from a few suppliers, hoping to get something in between.
Frankly i'm not too bothered if it's not exact match as long as it gives me a decent enough image and accuracy.
The camera is actually very useable for PCB inspection as it is and the image is good enough, that front lens seems to just be for further image field widening rather than anything else. I would even get a slightly wider lens as the default 24 degree is a bit narrow.
The focus can still be adjusted both manually and auto even with the front lens missing.
If a cheap and cheerful germanium lens gets me a fully working camera then i'll be happy, considering it’s a decent spec model.
I'll keep you updated with how things go once i found the right lens.
Thanks,
Dan.
