Now What Do IDo With It?

Well, you get someone who knows Fortran orCobol or whatever to convert your data to a formyou can use-and consume more time and moneyin the process.

An IDI Computer Controlled Display Systemeliminates this conversion-computation-conver-sion bottleneck because it makes the computerspeak your language-without an interpreter.Witha light pen, keyboard, track ball or other man-input device you feed graphic or alphanumericdata directly to the computer and your answercomes back in alphanumeric or graphic form-immediately usable without conversion.

If your efficiency is bottlenecked by the con-

stant need for data conversion, you need an IDIComputer Controlled Display System.

IDI Computer Controlled Display Systems areideally suited for such applications as:

* Computer aided * Command and Controldesign * Program debugging

* Management * Pattern recognitioninformation * Automatic CheckoutSystem Simulation Information retrieval,

* On-line problem solving

BetterPrecision Scales

and Rulings with the"CHROME-LINE" Process

"CHROME-LINE" is the name of the Bausch & Lomb PrecisionRuling Laboratory's unique vacuum depositing process. Itproduces a 99% opaque line on a clear surface which is easyto see and so wear-resistant it can't even be scraped off with aknife. Line widths can range from 80 millionths'of an inch tup,the thickness of the chrome deposit being typically 4 to 5millionths.We can produce the widest range of precision scales and

rulings to meet the exacting requirements of industry, educa-tion and research. We make high-precision single line slits,parallel and crossed line scales and grids, numbers, letters,special characters, circles, dots, arcs, multiple line Ronchirulings, linear scales, eyepiece reticles, resolution and align-ment targets, encoder discs and plates.

Deliveries are exceptionally fast. Many items are stockedand ready. For instance Ronchi rulings are available in aminimum line width of 2 microns and a +.25 micron minimumtolerance (depending on line width.) We have them from 1 x 1"to 1 x 60". And we can supply them up to a maximum 250 linepairs,mm.
