The JETI Specbos is one of the most affordable true reference color analyzers available on the market today. Just mount on a tripod, facing towards the source, connect to ChromaPure Professional and use as you would any other color analyzer.

At some point many professionals conclude that their work requires a reference colour analyzer. SMPTE has established standards for such a device. It must measure color accurately to within ±0.002 xy at or above 10 cd/m2 and luminance accurately to within ±0.5 cd/m2 for white field measurements. These are very exacting specifications that no tristimulus colorimeter can achieve, at least for chromaticity. For this level of accuracy you must have a 5nm spectroradiometer.

Unfortunately, such devices are not cheap. The Photo Research and Minolta reference devices start at about $15,000 USD and go up to near $30,000 USD. The X-Rite EyeOne Pro is reasonably affordable, but it is a 10nm device that cannot routinely achieve ±0.002 xy accuracy. Furthermore, in addition to being expensive, true reference devices also often suffer from practical limitations. They can be slow and have problems with low-light readings.

Recently, a German company JETI Reference Instruments has developed a reference spectroradiometer, the Specbos 1211, that solve most of these problems.

First, they are relatively affordable, that is at least what passes as "affordable" in the context of reference devices. Second, both are reasonably fast for higher luminance sources, and the 1211 is speedy even with low luminance sources. They are also amazingly compact and portable and both include a nifty laser spotter that allows for accurate aiming. The only feature these incredible devices give up to the established Photo Research and Minolta competitors is stand-alone operation. The Minolta and Photo Research alternatives allow for aiming through optical sights and readouts on a small LCD screen. They are fully functional devices without a PC. In contrast, the JETI devices work only when attached to a PC via USB with custom software (such as ChromaPure of course!). For display/home theater calibration this is a non-issue as you'll be using calibration software anyway.

First, it is relatively affordable, that is at least what passes as "affordable" in the context of reference devices. Second, it is speedy even with low luminance sources. In our testing the 1211 reads a 0.7 cd/m2 test pattern in about 13 seconds. Measurements of a 17 cd/m2 level pattern is 3 seconds or less. It is also amazingly compact and portable and includes a nifty laser spotter that allows for accurate aiming. Finally, it provides a built-in sync detector that ensures that readings will always be synchronized with the frequency of the display being measured. This feature guarantees excellent repeatability on all display types.

The 1211 can be used as a working color analyzer. Its speed and low-light sensitivity make it suitable for any calibration task—except perhaps reading black level—where the light level is so low even the 1211 often cannot cope. Fortunately, very low light levels can be accurately read with quite inexpensive instruments, such as the AEMC CA813 illuminance meter. The Display 3 will read down to about 0.007 cd/m2.

Technical Specifications

See the JETI Specbos order page for complete details.

Calibrating Front Projectors

For best accuracy, we recommend calibrating front projectors by taking readings directly off the screen. Our JETI Specbos 1211 kits include a tripod.

What's included

  • USB cable
  • Tripod
  • Diffuser (for illuminance readings)
  • Calibration certificate
  • Operating instructions
  • Transport box with foam insert
  • ChromaPure video calibration software on CD
  • The Hubble Colorimeter with carrying case
Calibration DVD

For your convenience we offer a simple calibration DVD that includes all of the test patterns that you'll need to perform a complete calibration of your display. This DVD is offered free as a complementary download.

Click here to download the DVD

Instructions:

1. Download the .zip file to your PC.
2. Unzip the contents, which is an .iso DVD image file, to your hard drive.
3. Double-click the .iso file.
4. If you have DVD burning software (e.g., Nero Burning ROM), the file will open.
Set the image type to DVD (not CD) if necessary.
5. Insert a blank, writable DVD into your DVD burner, and then burn the image.

Me too! As you probably guessed, this is not a meter for your average home theater user... Wink
