Microscopes with parallel lines

[Emer]

Is anyone aware of an inspection system which would allow one to have two parallel lines of measurement instead of the traditional crosshair of X /Y plane. I want to have one line as a baseline or zero point and be able to set the other line a particular distance away - and inspect if all the points I need to measure are in between somewhere.<br>
This technique also needs to be fairly ergonomically compliant as an operator will be looking in between these two lines for up to 10 hours!<br>
<br>
Can anyone help?<br>
Thanks,<br>

I just bought a system from OGP (Optical Gaging Products) that will meet those needs and many many more.

I am not too sure which application this is for but in Land surveying we use an optical device known as a parallel plate micrometer which will measure over say a 10mm range with intervals of 0.2mm . This device is usually fitted to a level allowing measurements from about 1m to 100m (although that is pushing the accuracy a bit)

In precise levelling we usually stick to about 50-70m sightings.

Try Edmund Scientific at

They have a whole section on microscope target optics, including parallel line measurement systems. Prices are reasonable. Kevin VanZuilen &quot;KevinVZ&quot;

&quot; Quality&quot; magazine's annual buyer's guidebook directory will provide you a number of suppliers. You could hook up an optical fiber ring with a light source and then hook it up to a monitor through a variable magnification microscope to get strainfree picture on a CRT. Check with Techmet Canada or any other similar supplier supplying PCB inspection equipment.
