Holding tray without UVB-block: Light with wavelengths in the rage of 280 to 950 nm can pass through the holding trays.
The type of tray necessary to avoid yellowing of the workpiece, for example, depends on the resin you
are using (please refer to requirements as specified by the manufacturer or distributor).
Important:
A tray insert is strictly necessary when operating the device using the protective gas function.
The holding trays are designed to be used with nitrogen (N2). You must contact the device
manufacturer (NK-Optik GmbH) if you intend to use a different inert protective gas (e.g. argon or
carbon dioxide) to identify appropriate alternative trays.
Never use alcohol or alcohol-based cleaning products to clean the holding trays!
The holding trays have a limited lifetime due to the high-intensity irradiation they are subjected to. The
trays should be replaced after approximately 50 hours of usage time. In addition to this, the trays
should be replaced if they exhibit strong yellowing, or have been severely scratched or dirtied.
