Plate Copying Exposure Lamp

This type of lamp is made of high-purity quartz pipe filled with iodides of mercury, cobalt and gallium, iodides of iron and haloids of some rare metal. It is commonly known as plate copying lamp. Its spectrum is mainly between 315 mm–450 mm.

This type of lamp is made of high-purity quartz pipe filled with iodides of mercury, cobalt and gallium, iodides of iron and haloids of some rare metal. It is commonly known as plate copying lamp. Its spectrum is mainly between 315 mm–450 mm. The main wave peak is 420 nm. The power varies from 1–7 kW. Characterized by long service life, stable electric arc, high intensity and good exposure quality, this lamp is applied to plate copying exposure of photosensitive materials such as non-silver salt film (diazonium salt film and photoemulsion), resistance welding dry film, wet film, green resistance welding flux, resin plate, PS plate, film, silk screen, PCB diazo film, etc.
