Xenon Lamp
Xenon lamps emit a continuous spectrum, ranging from the UV to visible to infrared, with high luminance and high color temperature. Hamamatsu lamps employ a high-performance cathode, so they maintain a stable arc point even after many hours of use unlike conventional lamps. Ideal for photometric equipment such as spectrophotometers, and other applications where high-precision measurement lamps are necessary.
ARC POINT "INSTABILITY (FLUCTUATION)" AND "SHIFT"
Light source lamps used for high precision photometry must have good arc emission point 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.
STRUCTURE AND OPERATION
These lamps have an oval bulb in which a cathode and an anode face each other. The bulb for super-quiet xenon lamps is filled with high-purity, high-pressure xenon gas. The bulb for super-quiet mercury-xenon lamps is filled with a mixture of high-purity, high-pressure xenon gas and high-purity mercury. The lamps emit light by arc discharge. The lamps are installed vertically or horizontally with the anode at the upper side (some types of lamps are only installed vertically) and operate on DC (when the specified voltage is supplied across the anode and cathode, the lamp forms an arc discharge). After the lamp lights up, the light output intensity varies until the gas pressure inside the bulb reaches thermal equilibrium. It takes several minutes to reach the maximum light output intensity. During lamp operation, the bulb wall temperature rises above 500 °C and the gas pressure inside the bulb increases to approximately 4 MPa which is 4 times higher than when the lamp is not operating.
SUPER-QUIET XENON LAMPS
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 (185 nm to 2000 nm) from the UV to infrared region. These xenon lamps are ideal as light sources for various types of photometric instruments such as spectrophotometers.
