Gallium uv lamp
UV lamps are classified into product use and pressure.
The classification of product use differs by the UV wavelength range applied to manufactured products.
For instance, curing lamp requires 365/420nm ultraviolet rays, and hardens resin for UV curing, ink, and adhesives.
Classification according to pressure refers to pressure of UV lamp. In case of low pressure UV lamp, pressure arises around hundreds of Torr, wall temperatures range around approximately 40?, and UV wavelength range is usuallyaround 184.9 and 253.7nm.
This is a lamp inserted with Gal3, not Fel2 of metal halide salt. Since this lamp emits 420mm violet ray, it is extensively used in Diaz film light exposure film developing and etching industry. It is under extensive use because it has strong penetrating power on products with coating thickness of over 30? such as high glossy furniture and shadow mask.
