摘要

The screen has a modular structure for fixing different filters in different heights and for holding impinging back and side lights, where the screen is modularly designed from individual planar layers. The individual layers are held together by easily accessible knurled screws that are tightened and loosened with fingers. The layers have a thickness of 6-8 millimeter (mm). An object holder (1) has inner diameter of 50 mm.
