Technical Parameters

Parameter	Description
Light source	Composed of carbon arcs between upper and lower carbon rods, the arc voltage and arc current can be adjusted according to specific models. For example, some models have an arc voltage of 50V and an arc current of 60A.
Filter	Use specific glass filters, such as the Korex 7058 glass filter, to reduce unwanted radiation.
Temperature range	The temperature inside the test chamber can be adjusted as needed, usually within a certain temperature range, such as 0-80 °C.
