Does any one know of a stand alone anti-glare screen for the Sun 2/120 graphics monitor? The monitor is produced by Moniterm Corp. and they were not aware of any such device. It is a 19 inch monochrome display with 16.5"x13.5" flush cabinetry opening. The monitor can be purchased with an anti-glare coating but this is not field installable ( unless you have a vacuum form machine handy :-). Thanks in advance for any information.

Optical Coating Laboratory, Incorporated makes a proprietary anti glare coating for CRT manufacturers. It works by coating a layer above the glass such that the layer is 1/4 wavelength at the frequency of interest and is reflected back from the glass/coating layer...voila, destructive cancellation. Since the layer has an optical refractive index of ( n ** 1/2 ???) where n is the glass r. i., the image coming from the CRT phosphour is not diffused... First, if you are willing to go to a LOT of trouble, the CRT which was put in your terminal is ** Probably ** available in an OCLI version. Second, OCLI makes their neat stuff in sheet stock which they would be glad to cut up for you to the right size.

In response to the message about OCLI (Optical Coating Laboratories): I think the stuff is GREAT! It's basically the same stuff you see on good camera lenses -- magnesium fluoride, I think. Nothing I've seen can approach it for preventing glare and enhancing contrast. The screen is absolutely a FLAT dark dark grey with no reflections at ALL, unless you get off to one side of the monitor and shine a bright light at it. All DEC PCs (DECmate, Rainbow, Pro) used to come with OCLI stuff on their screens. Unfortunately, DEC decided it cost more than it was worth so they've switched to etching the glass (like IBM, bleah). Apparently the cost to DEC, even in the enormous quantities DEC was buying, was around $60 per CRT, which is steep. There is one drawback, besides cost: it fingerpints very easily, and you have to be careful about cleaning it. I like it so much I've just gotten used to not touching the screen with my fingers -- I use a pen to point at things on the screen. I wish some of the 3rd-party vendors of monitors would start using OCLI -- I'd love to get it on my PC/AT. - Larry Campbell The Boston Software Works, Inc., 120 Fulton St., Boston MA 02109 UUCP: {decvax, security, linus, mit-eddie}!genrad!enmasse!maynard!campbell ARPA: decvax!genrad!enmasse!maynard!campbell@DECWRL.ARPA

SUN used to offer this on their 19" tube; the option was about $500; we bought four, and it worked quite well. In terms of cost, it's a win over having to install lamp dimmers, special work areas, etc. for places with big brightly-lit rooms. But SUN discontinued it, unfortunately; too few customers ordered it. John Nagle
