ChromaPure Professional with a JETI Spectraval Reference Spectroradiometer
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 (pictured on the left) must be controlled by PC software, just like the JETI 1211. However, 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. To top it off, the Spectraval units are less expensive than the 1211.
Hi-Res Option
Both the 1501 and the 1511 come in a High Resolution configuration. This version of the meters differs from the standard version in two ways:
- It offers a higher optical resolution of 2nm
- It is less sensitive, so readings take about twice as long to complete.
The purpose of this option is to offer an instrument whose resolution is high enough that it can accurately measure new displays, specifically RGB laser projectors, that exhibit a very narrow spectral response for the three primary colors. The vast majority of laser projectors are not RGB devices, but blue lasers with a phosphor that separates the blue light into red and green components. This much more common design does not require the hi-resolution option.
Summary
The JETI Spectraval 1501 spectroradiometer is the most affordable true reference device available, and 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.
