Color Analyzers
<< Back to Calibrators
Greetings
I continue to use my Philips analyzer for CRT based technologies like direct views and
RPTVs ... because it is the most accurate of the colour analyzers in this group and it is
portable and gives me fast results. Unfortunately, the unit has now seen too many miles
and parts of it are breaking down. And no new parts exist since Philips left this business
behind many years ago.
Secondary CRT devices I continue to use and trust are the Progressive Labs analyzers. I
have three of them because they represent the three versions that have existed over the
past 5 years.
Version 1 was only for CRT's but could used offset files for other display types. This
was the same technology as the Sencore CP 288 unit.
Version 2 was the all displays probe similar to the Sencore CP5000 unit. It was and is
marketed as compatible with all display types be they plasma, CRT, LCD, DLP, LCOS ...
unfortunately field results by myself and many other known calibrators found that the CRT
part was dead on, but the results for the other display technologies were mediocre to
questionable. We were getting images that plain looked wrong. Like the previous version,
response and sensitivity on the dark end was not the best. (Philips so much better here).
Version 3 is the current model that is still billed as all displays, but has far
greater sensitivity on the dark end and better accuracy too. The software has been
improved and updated as well with this version. While the jury is still out on how good
this one is on the LCD/DLP/Plasma etc sets, initial experiences are not promising. It
seems to give the same results as the Version 2 pod. Version 3 is also much better now for
FPTV applications as it can be tripod mounted and pointed at the screen to account for the
effect of the screen material on the image.
The final analyzer I use is the Milor/Colorfacts CF6000 spectrometer. This is the
device that the colour analyzers are trying to emmulate ... although not this device. The
CF6000 is used by me primarily on LCD / DLP / Plasma and other technologies although it
too can be used on CRT devices. This is the device that isn't supposed to get fooled by
the light output of the other display types. It is also the primary tool for working on
FPTV set ups because it takes its light readings directly off the screen surface. The down
side of the device is that it too have less than desirable sensitivity in the dark end and
it needs to be constantly "zero'd out" to work at optimal levels. The unit needs
a dark reading at the start of the use period, but usually needs to be reset every 20
minutes of use. Problem is, if you are not careful, the results you get at minute 19
versus the results right after a reset are very different. Results at minute 10 are much
closer to those at the start point.
Hope this helps. A bit more than what you asked for. The TVS Pro is the optical
comparator that looks like a star trek tricorder. It is very good for double checking the
accuracy of the sensor devices that we use ... but it too needs to be checked out every so
often (400 hours of use) as its reference images turn green.
Regards
