PX-2 Pulsed Xenon Light Source

PX-2 Pulsed Xenon Light Source; The PX-2 Pulsed Xenon Light Source is a high-flash-rate, short-arc xenon lamp that emits ultraviolet light (wavelength 220–750 nm); it is suitable for applications requiring measurement of light absorption and; reflection, or observation of fluorescence and phosphorescence, and is especially used for testing samples that are unstable to light or heat.; The PX-2 Pulsed Xenon Light Source has an operating rate of up to 220 Hz, with excellent pulse; switching stability, and its flash frequency software control has two trigger modes.; The PX-2 Pulsed Xenon Light Source is a high-flash-rate, short-arc xenon lamp that emits ultraviolet light (wavelength 220–750 nm), suitable for applications requiring measurement of light absorption and reflection, or observation of fluorescence and phosphorescence, and especially for testing samples that are unstable to light or heat.; The PX-2 Pulsed Xenon Light Source has an operating rate of up to 220 Hz, with excellent pulse switching stability, and its flash frequency software control has two trigger modes.; If a higher-brightness xenon light source is required, consider purchasing the HPX-2000 Xenon Light Source. The HPX-2000 Xenon Light Source is a continuous-wave short-arc lamp with a power of 35 W and a wavelength range of 185 nm–2.2 μm.; About the PX-2 Pulsed Xenon Light Source; Any model's external TTL positive pulse level can trigger the PX-2 Pulsed Xenon Light Source. Users can combine the PX-2 Pulsed Xenon Light Source with the S2000 Spectrometer for very convenient simultaneous operation of the light source and detector.; The PX-2 Pulsed Xenon Light Source can switch between two operating modes and select the TTL signal: composite mode and single mode. In composite mode, the flash timing is an invariant, set by the S2000 Spectrometer's jumper module. The spectrometer's sampling can be varied to facilitate observation of the number of flashes within each different integration time. Because composite mode ensures a stable and consistent light source within each integration period, it is especially suitable for measuring light absorption and reflection.; In single mode operation of the PX-2 Pulsed Xenon Light Source, only one single flash occurs within each integration period, and its flash frequency is adjusted by changing the integration time.; Because the PX-2 Xenon Light Source produces a pulsed signal, it does not easily contribute to the solarization effect of the fiber optic cable, which is generated when the fiber transmits optical signals with wavelengths below 260 nm.; Other features and information on connection features; The power supply provided with the PX-2 Pulsed Xenon Light Source is 12 V DC; users may also use a battery (to be provided by the user) as the power supply (for more help, please contact the application scientists of Ocean Optics, Inc.).; The PX-2 Pulsed Xenon Light Source is equipped with a 15-pin connector, which can be used to connect it to a spectrometer. The PX-2 Pulsed Xenon Light Source is also equipped with an SMA905 connector, which can connect to Ocean Optics, Inc. miniature fiber optic spectrometers and other fiber optic components, such as optical fibers, cuvette holders, probes, and other sampling components. Users can also additionally purchase the CUV-FL-DA for use with the PX-2 Pulsed Xenon Light Source; it is a directly attached cuvette accessory that can be used for absorbance and fluorescence testing. The CUV-FL-DA is priced at 399 US dollars.; Spectral output curve of the PX-2 Pulsed Xenon Light Source; Spectral range; 220-750 nm; Approximate dimensions; Length 14 cm x width 10.5 cm x height 4 cm; Power input; 1.3 A, 11 V, 220 Hz; 100 mA, 12 V, 10 Hz; Trigger input; External TTL positive pulse level connected via 15-pin connector; Output; Maximum 45 mJ per pulse; Pulse duration; 5 ms (at 1/3 pulse height); Lifetime; 10^9 pulses (continuous operation at 50 Hz pulse frequency for approximately 230 days); Slit; 3 mm; Connector; SMA 905; Timing signal obtained from the S2000 Spectrometer; In composite mode: up to 220 Hz (varies with analog/digital sampling frequency); In single mode: varies with scan rate; Ordering information for the PX-2 Pulsed Xenon Light Source; Model; Miniature Pulsed Xenon Light Source, spectral range ultraviolet–visible (220–750 nm); Replacement bulb dedicated to the PX-2 Pulsed Xenon Light Source; PX-2 firmware; USB2000 version spectrometer firmware, used to operate the PX-2 Pulsed Xenon Light Source in pulse mode; Product description: The PX-2 Pulsed Xenon Light Source is a high-flash-rate, short-arc xenon lamp that emits ultraviolet light (wavelength 220–750 nm), suitable for applications requiring measurement of light absorption and reflection, or observation of fluorescence and phosphorescence, and especially for testing samples that are unstable to light or heat. The PX-2 Pulsed Xenon Light Source has an operating rate of up to 220 Hz, with excellent pulse switching stability, and its flash frequency software control has two trigger modes.
