Ocean Optics has introduced a high-intensity pulsed xenon light source option for its Jaz modular sensing system.
The Jaz-PX is a high flash rate, short-arc xenon lamp especially useful for UV-Vis applications such as absorbance, bioreflectance, fluorescence and phosphorescence.
The lamp has maximum pulse frequency of 500Hz and spectral response from 190-1,000nm.
Jaz is a family of stackable, modular components that share common electronics and communications.
At its core is a miniature linear CCD-array spectrometer, available with user-selected grating and entrance slit optimised for a variety of application needs, in a design that accommodates up to eight spectrometer channels.
Each Jaz stack includes an onboard microprocessor and display, which eliminates the need for a PC.
Additional Jaz modules are available for battery operation and Ethernet connectivity, as well as for sample illumination (via UV-Vis and Vis-NIR sources) and excitation (via LEDs).
The Jaz-PX operates in both free running and triggered modes, which allow its pulses to be co-ordinated with other devices in the Jaz stack.
Flash-to-flash stability is <1 per cent and the flash rate is 500Hz.
Jaz-PX has an SMA 905 connector that couples to Ocean Optics accessories, including optical fibres, cuvette holders, probes and other sampling optics.
Because it produces a pulsed signal, the Jaz-PX is less likely to cause solarisation in optical fibre assemblies, which can occur when fibres are illuminated with signal <260nm.
In addition, Jaz can be configured for a variety of field, laboratory and process setups.
The Jaz-PX is ideal for field applications such as bioreflectance that require a high-intensity, low-power source as no external power supply is required.
When used in the field, the lamp will operate from the power of the battery for approximately 3.5-4 hours.
Additional power is available through an optional 50 W/hour Jaz battery extender.
