This standard quartz lamp tubing is a kind of clear electrically fused machine-drawn tubing. It has characteristics of excellent visual, thermal, mechanical properties with tight dimensional tolerances. This material is available in a full range between 2mm and 200mm outside diameter. The hydroxyl (OH) content can be adjusted to different level according to its application.
However, it still has a transmission of over 85% at wavelength 253.7nm which is ideal for making water purifying lamps and other UV germicidal lamps, because these UV lamps emit about 90% of their radiated energy at 253.7nm which makes the peak germicidal effectives occur.
This has a very good transmission at visible light range from wavelength 380-720nm. So this low cost material is accepted world widely for making halogen lamps, high pressure mercury vapor (HPMV) lamps and other lamps of general lighting system.
The large diameter can also be used in other lower temperature industrial field due to its anti-alkali and anti-acid properties such as chemical industry and lower temperature semiconductor industry etc.
Application in combination with its different Hydroxyl (OH) content is as
1. UB=Unbaked; NB=Normal Baked; EB=Extra Baked; SB=Super Baked; GLS=General Lighting System; HPMV=High Pressure Mercury Vapor; MH=Metal Halide.2. Wavelength: Vacuum UV=10-200nm UV-C = 200-280nm UV-B
= 280-315nm UV-A = 315-380nm Visible Light =380-720nm
