High Transmittance Ozone Free Quartz Tube

Application:

Germicidal, water treatment lamp

Application High Transmittance Ozone Free Quartz Tub

Product Feature:

It is a kind of doped transparent quartz tube that absorbs part of UV-C and has a high transmittance (typical transmittance > 88%) at 254nn in the ultraviolet region, which can satisfy lamp special requirements at the ultraviolet region.
