Good day to all. I have a very old B&W video-based microfiche viewer that I=20 affectionately refer to as my "Black & White Microscope". Although=20 the intended use was as a microfiche reader, it has served me well=20 over the years for doing SMD assembly. Even though the image is only=20 black and white, it has gorgeous resolution and the movable X-Y table=20 allows for easy pcb movement during assembly. But it is ancient and it now needs work. The obvious thing to do is=20 to convert it to modern technology: a modern camera that can feed a=20 standard LCD monitor. This unit has an incredibly gorgeous lens assembly that sits=20 horizontally above the movable table and below the 12" B&W=20 monitor. There is a 1/2" Vidicon at the rear of the lens assembly=20 and an angled mirror at the front that allows the front of the lens=20 to see the work surface below. The Zoom and Focus are mechanical controls that are part of the lens assemb= ly. Really and truly - all that I think that I need to do is to find a=20 modern video camera that will take the place of the original 1/2"=20 vidicon. I would also need some form of interposing electronics that=20 will allow the camera to be displayed on a modern LCD=20 monitor. Although I'm partial to standard VGA resolution, I would=20 happily consider a HDMI connection. But I don't know where to start looking for appropriate devices. I=20 know just enough about video to be dangerous and I have absolutely no=20 idea where to start looking for a suitable camera and interface electronics= .. One requirement in particular is low latency. I have used=20 inexpensive USB microscopes in the past but I find the video lag to=20 be almost unusable for assembly purposes. I'm in Canada, so if the camera needs to match a TV Broadcast=20 standard, it would have to be NTSC. But I'm hoping that I don't need=20 to worry about that - all I want is a camera that is able to feed a=20 LCD monitor with VGA or HDMI input connector. I was going to post this question in electronics.stackexchange but=20 because this is more of a shopping question rather than design, it=20 probably wouldn't get very far before being closed. Guidance and suggestions gratefully accepted.
