FAQ: Which meter
is right for me?
The JETI Spectraval 1501/1511 spectroradiometers are the most affordable
true reference device available. The Spectraval 1511 is less expensive than the
JETI 1211 with similar performance and significantly enhanced user flexibility.
Just mount either on a tripod, facing towards the source, connect to ChromaPure
Professional and use as you would any other color analyzer.
Coming off the enormous success of the JETI
1211, JETI has developed a new line of reference spectroradiometers that
seek to offer equivalent performance to the 1211 at an even lower cost and with
increased user flexibility.
This effort has resulted in two new products, the Spectraval 1501 and
Spectraval 1511. Each performs the same, but offer different user interfaces.
The 1501 must be controlled by PC software, just like the JETI 1211. The 1511
adds a small LCD screen that allows the user to take measurements and view
results without ever connecting to a PC. However, at some point in the display
measurement process you will probably want to connect to video calibration
software for analysis and reporting, which is why we offer the Spectraval 1511
bundled with ChromaPure Professional.
Both the 1501 and 1511 offer built-in Bluetooth, which allows wireless
connection to the PC for added user flexibility. Otherwise, the Spectraval units
offer similar speed, accuracy, and repeatability to the 1211 in addition to
offering even higher dynamic range through greater maximum luminance. The 1211
offers a wider spectral range, but this is unnecesary for measurements in the
visible range that we care about in home theater. To top it off, the Spectraval
units are less expensive than the 1211.
What are the "HiRes" versions?
The high-resolution (HiRes) versions were especially
developed for the measurement of RGB laser projectors and displays. They have an
optical resolution of better than 2 nm (instead of 4.5 nm), so they allow a
precise measurement of narrow bandwidth spectra. Sensitivity is lower as of
the standard versions, but this is not significant in case of such light sources.
The white signal of a RGB Laser projector consists of three narrow signals of
red, green and blue, which form a large and impressive color gamut. It is
helpful to use a spectroradiometer with a higher optical resolution for the
calibration of such projectors. Note that measuring time will be 4 times longer
than standard Spectraval.
Why buy a JETI Spectraval 15x1 instead of a JETI Specbos 12x1?
The JETI Spectraval 1501 is the replacement of Specbos 1201. It covers the same
spectral range (VIS), but is about ten times more sensitive. Therefore it can be
used for low light applications in the same manner as specbos 1211, where
specbos 1201 was not recommended for such as the calibration of monitors.
Spectraval 1501 is intended for Radiance mode measurements only, a diffusor,
which is included in the specbos 1201 delivery, has to be ordered separately
(ACC 032). If a stand alone solution is needed, then spectraval 1511 can be
used. It has the identical parameters as spectraval 1501, but is equipped with
display and SD card reader.
Choose Spectraval 1501/1511 over of Specbos 1211 for the followign reasons:
- If a wavelength range beyond visible is not needed (version of
spectraval 15x1 up to 1 μm is planned)
- If no accessories other than a diffusor are needed (currently only a
diffusor is available for spectraval)
- If a luminance measurement above around 3500 cd/m2 is needed (illum. A –
5000 cd/m2, typical white LED – 3500 cd/m2 for specbos 1211, values up to
100 000 cd/m2 for spectraval)
- If a stand-alone operation is needed (spectraval 1511 is equipped with
display and SC card slot)
- If a wireless connection is preferred (spectraval is equipped with
Bluetooth interface by default)
