The high flash rate that has been trending in the market is a 2W pulsed xenon light source which is quite efficient. This lamp is a short-arc xenon lamp with an output from 220-750 nm. It works at the speed of 220 Hz. It is known to offer the best pulse to pulse stability which can be triggered with an external TTL pulse. It is extremely easy to use and comes with software control. It is durable and compared to other flash sources which make it further in demand.
Overview of PX-2
To trigger the PX-2, it is possible to use the external TTL positive pulse. If it is blended with an S2000 Spectrometer the user can then synchronize the light operation along with the detector without any hassle.
One of the best parts of its 2W pulsed xenon light source is the feature to switch to choose the TTL signal that comes with two operational modes. If the multiple modes are chosen the flash timing can be invariant. It is adjusted using the jumper blocks in the S2000.
It is possible to change the spectrometer so the flash’s variable number can be united at every integration period. In the case of the multiple modes, it can be used for reflection application and absorbance. It makes sure there is a steadiness and better light exposure for the integration span.
What is the purpose of the pulsed light source?
The Spectrometer sampling can be changed as per the variable number of flashes that are noticed in the integration span. Suppose in the single-mode operation, the single flash will appear in the integration span. This way it is possible to synchronize the detector and xenon lamp. If there are many modes, then it requires a light exposure that will be consistent and steady. The same is offered by a 2W pulsed xenon light source for every integration period. This would make sure the absorbance is repayable while reflection measurements are accurate.

Additional Features to not ignore about Interface Features
The light source is designed with a 15-pin interface cable that connects the spectrometer and lamp. The PX 2 comes with SMA 905 connector which is attached to the Ocean Optics miniature fiber optic spectrometers. It is also connected with accessories such as cuvette holders, optical fibers, and probes to name some. CUV-FL-DA can also be used with PX2 which is the cuvette accessory that can be attached directly for the measurement of fluorescence and absorbance.
Further studies have also shown that Pulsed-xenon-ultraviolet light can be used in the healthcare sector as a supplemental disinfection option. However, there is still a systematic search on the same that is going on using many databases. There is also a meta-analysis that is further conducted for evaluating the PX efficacy to reduce different infections.
Conclusion:
PX-2 Pulsed Xenon light source is a lamp with a high flash rate. It is a short arc xenon lamp that is used for ultraviolet light. Along with reflection measurement, it can be used for absorbance. There is also output from 220-750 nm. Due to the short duty cycle, the PX 2 is best for measuring phosphorescence. With so many advantages, there is no doubt that it is worth using this option. At the speed of 220 Hz, there is amazing stability from pulse to pulse which further can be triggered using the external TTL pulse.
