New Ocean Optics Light-Measurement Device for Convenient Analysis of LEDs

Jaz is a family of stackable, modular and autonomous components that share common electronics and communications. Included in the Jaz stack is a CCD-array spectrometer that can be optimized for a variety of radiometric measurements and a microprocessor with onboard display. Unlike traditional light meters, Jaz allows users to capture, process and store full spectra without the need for a PC. Spectral data can be transferred to a laptop or desktop PC for additional post-acquisition processing, such as calculating colour temperature, spectral intensity and colour space values.

Jaz’s Ethernet and battery modules offer unmatched portability. The Ethernet module has data storage capability via an SD card slot and allows users to connect to the Jaz unit via the Internet -- making remote measurements such as solar irradiance possible and enabling the creation of networked sensing modules. The Lithium-Ion battery module is rechargeable in the field via a solar cell or in the QC lab using the Power over Ethernet connection (100 Mbps, IEEE 802.3-compliant 10/100 single-cable), the USB 2.0 port or an external power supply. The battery module also has a power-conserving sleep mode for long-term measurements and two additional SD card slots for storing data.

“Jaz offers an attractive combination of spectral sensing power and handheld portability for all sorts of lighting measurements,” says Mike Kayat, Ocean Optics Vice President of Sales & Marketing. “As energy savings and cost concerns help drive demand for more efficient LEDs and other types of lighting, the value of simple, convenient diagnostic instrumentation is magnified.”

The Jaz platform also expands to include light sources (VIS-NIR or LED) and additional spectrometer channels. Jaz can be connected to fibre optic sampling accessories such as integrating spheres (for collecting emission with a 360-degree Field of View), cosine correctors (collecting with 180-degree Field of View) and optical fibres. An add-on holster accessory makes the Jaz wearable, freeing hands to manipulate sampling devices.
