Options to inspect a cartridge from below - mirrored loope, endoscope?

I would like to order a device to look at the underside of my cartridge without pulling the cartridge off my tone arm

Just staring from the side doesn’t cut it. One with a light would be ideal although I can point my snake arm turntable light in the area I am looking at.

If there is the option to transmit the image to my ipad, phone, etc (wireless or broadcast / snapshot, usb) - that would be great

Does anyone make a mirrored magnifying

High magnification would be great, variable nice too

Has anyone used an endoscope? Digital flexible inspection camera? DIno lite hand held microscopes?

I don’t mind spending some nice coin (but not too nice) as I can use it in some science projects as well.

Thanks

Tom
