LONG LIFE 100W XENON SHORT ARC REFLECTOR LAMP L10878
 Catalog (190 kB)
The L10878 consists of a long-life 100 W xenon lamp precisely assembled with a condenser reflector. The L10878 does not require optical systems and optical axis adjustment mechanisms that are necessary for ordinary xenon lamps. This simplifies equipment design and makes lamp replacement easy since no optical axis adjustment is required.

OVERVIEW
=== Super-Quiet Xenon Lamp ===
These are lamps filled with xenon gas that emits "white light" at a high color temperature of 6000 K, which is close to that of sunlight and covers a broad continuous spectrum from the ultraviolet to infrared region (185 nm to 2000 nm). These xenon lamps are ideal as light sources for various types of photometric instruments such as spectrophotometers.
|
=== Super-Quiet Mercury-Xenon Lamp ===
Mercury-xenon lamps produce high radiant energy especially in the ultraviolet region due to an optimal mixture of mercury and xenon gas. These lamps possess features of both xenon gas and mercury discharge lamps. The spectral distribution includes a continuous spectrum ranging from ultraviolet to infrared of the xenon gas and strong mercury line spectra in the ultraviolet to visible region.
Compared to xenon lamps, the radiant spectrum in the ultraviolet region of mercury-xenon lamps is sharper in width and its peak is higher in intensity. These features make mercury-xenon lamps ideal as ultraviolet light sources.

ARC "INSTABILITY (FLUCTUATION)" and "SHIFT"
Light source lamps used for high precision photometry must have good arc stability. However, cathodes used in conventional lamps have two shortcomings in terms of arc stability. One problem is that the arc emission point shifts intermittently due to inadequate electron emission from the cathode. The other problem is that the arc point shifts a little at a time due to the cathode tip wear that occurs with operating time as the lamp ages.
Hamamatsu super-quiet lamps employ a high performance "BI (Barium-Impregnated) cathode" developed totally in-house that eliminates the above problems to deliver extremely high stability. This durable cathode exhibits no wear at the cathode tip over operating time and the arc point does not shift. So there is no need to realign the optical system until the time finally comes when the lamp must be replaced. |
