5 / 7 page TLSOB0038EC Extremely high stability of intensity is required for deuterium lamps because of their applications. Therefore, use of a power supply designed to drive the lamps with stable operation is recommended. Hamamatsu , s power supply for deuterium lamps uses a constant-current circuit in the main power supply section and a constant-voltage circuit in the filament power supply section to assure a reliable operation. Hamamatsu offers not only OEM power supplies specially designed for your applications, as well as the following types according to the operation mode of various lamps. SPECIFICATIONS L2D2 Lamps (Deuterium Lamps ) TECHNICAL INFORMATION The following 4 types of window material are available for deuterium lamps. (1) UV glass (2) Synthetic silica (3) MgF2 Figure 2 shows the transmittance of various window materials. UV light at wavelengths shorter than 190 nm attenuates greatly due to its absorption by oxygen. To obtain the fullest performance in window trans- mittance, it is recommended that the inside of the equipment be filled with nitrogen or vacuum-evacuated to eliminate this absorption effect. The non-projecting type uses the side of the cylindrical glass bulb as the emission window, whilst the projecting type uses a plane glass attached to a projection on the bulb. The projecting type has a uniformed transmittance due to the plane glass. Since the window is located far from the discharge position, the amount of dirt produced by spattering from the electrodes is reduced resulting in low deterioration of light output. The non-projecting type requires less space and has a wider directivity since there is no projection, enabling effective use of emitted light. The long-nose projecting type uses an MgF2 window and is suitable for vacuum ultraviolet applications. This type is used with the tip of the nose inserted into the vacuum equipment. Spectral Distribution Window Material Figure 1: Spectral Distribution Figure 2: Typical Transmittance of Various Window Materials GUV glass GSynthetic silica GMgF2 TLSOB0024ED Light Distribution Deuterium lamps emit high intensity light in the UV range at wavelengths shorter than 400 nm. Light intensity on the short wavelength side is deter- mined by the window material used. UV glass has a higher ultraviolet transmittance than normal optical glass (borosilicate glass). It has the longest cut off wavelength of 185 nm among the four types. However the generation of ozone is lower than other wind- ow material types, it is not necessary to have special anti-ozone treat- ments. Synthetic silica is obtained by fusing a silica crystal that is artificially grown. Although its cut off wavelength is 160 nm, it contains less impuri- ties than fused silica, and transmittance at 200 nm has been improved by approx. 50 %. MgF2 is a crystallized form of alkali metal halide that has an excellent ultraviolet transmittance, a low deliquescence and is used as window material for vacuum ultraviolet applications. Its cut off wavelength is 115 nm.

Figure 5 shows typical spectral distributions for lamps with different aperture sizes. At the same input current and voltage, lamps with an aperture of 0.5 mm diameter (high brightness type) provide 1.6 times higher brightness than lamps with an aperture of 1.0 mm diameter (standard type). The half width of spectral distribution also becomes narrower with a reduced aper- ture size. When higher intensity is required or the object to be irradiated is very small, the high brightness type is recommended. 8 HEATER VOLTAGE AND CURRENT 160 200 240 280 320 360 400 WAVELENGTH (nm) 0.5 0.1 0.05 0.01 UV GLASS SYNTHETIC SILICA (PROJECTING TYPE, 1 mm THICK) 200 250 300 350 150 100 WAVELENGTH (nm) 20 40 60 80 100 UV GLASS SYNTHETIC SILICA MgF2 30 ° 10 ° 20 ° 0 10 ° 20 ° 30 ° C1518 TLSOF0068 TLSOF0150 TLSOF0150 C7860 M7628 7 POWER SUPPLY Control Methode Input Output Ambient Temperature Cooling Dimensions (W × H × D) Weight Certification C1518 (2.5 V) C1518 (10 V) C1518 (SQ2.5 V) C1518 (SQ10 V) C7860/M7628-2510 C7860/M7628-2517 A C7860/M7628-3000 A C7860/M7628-1035 A C7860/M7628-1070 C7860/M7628-1555 A NOTE A C7860 series are manufactured only when the order is placed. * Characteristics are measured at 23 ±1 °C after 30 min of warming up. 2.5 ± 0.2 10 ± 1 2.5 ± 0.2 10 ± 1 2.5 ± 0.15 2.5 ± 0.15 3 ± 0.15 10 ± 0.5 10 ± 0.5 15 ± 0.75 L6565, L7293, L6999, L6999-50 L7307, L7174, L6301, L6302 L6307, L6308, L7292 L7298, L6303, L6304, L7306 L7296, L7295, L6309, L6310, L7296-50 L6565, L7293, L6999, L6999-50 L7307, L7174, L6301, L6302 L7298, L6303, L6304, L7306 L6566, L6305, L6306 L6307, L6308, L7292 L7296, L7295, L6309, L6310, L7296-50 L6311, L6311-50, L6312, L6312-50 Input Voltage Input Wattage Output Voltage Output Current Trigger Voltage Fluctuation (p-p) Drift Output Voltage Output Current Warm-up Time Dropper Type (AC) 100/118/230 ±10 % 100 (DC) 80 (DC) 160 300 600 ± 50 0.1 ±0.1 See below See below 20 0 to +40 Not required 200 × 107 × 240 6.7 — Switching Type (DC) 24 ± 2.4 48 (DC) 80 (DC) 160 300 600 ± 50 0.5 ±0.1 See below See below 25 0 to +40 20 CMF of forced air 100 × 118 × 36.2 0.17 UL/CE — V VA Max.
