- The windowis a flat plane, and uniform transmittance can be obtained.
- The window
does not become dirty easily, and the light emission does not decrease
easily. |

| [Spectral characteristics] |
 |
- Synthetic quartz: Transmission of@ultraviolet rays is high. Durability against ultraviolet rays is outstanding.
- UV transmission glass: Since less ozone is generated compared with synthetic quartz, no measures against ozone are necessary.

Guarantee period of a Lamp
A lamp is guaranteed for 1 year form its delivery date. |
Cautions on using Lamps
- While lit, harmful ultraviolet rays are generated. Do
not look at the lamp directly without protective glasses, nor expose your body
to the ultraviolet rays.
- While lit or just after turning off, the lamp is very
hot (higher than 200). Do not
touch the lamp directly.
- Dirty window of the lamp decreases transmission of the
ultraviolet rays. If dirty, wipe the window with a clear cloth moistened with
alcohol.
- High voltage is applied to start the lamp. Be careful
about electric shock hazard.
- Do not fix the lamp by holding the nose part because it
breaks easily.
