For the preparation of flow cells and flow cavities for measuring chemical reactions under strong coupling using laser infrared spectroscopy, Caf2 windows of high quality (as little scattered light as possible) and with defined holes (inlet/outlet of the sample into the measuring cell) are required. The measuring cell is modified according to Bredenbeck et al, J.sci. Instr. 2003 and Caf2 windows with the requested quality are crucial for the signal quality and tightness of the cells. Caf2 window (ir) Ø 25.4(±0.1) mm x 2(±0.1) mm Optically polished on both sides Flatness: Lambda/2 @ 633 Nm S/d: 20/10 - 60 pieces Caf2 window (ir) With holes Ø 25.4(±0.2)mm x 2(±0.1)mm Optically polished on both sides Flatness: Lambda/2 @ 633 Nm S/d: 20/10 With 2 holes Ø 0.8(±0.1) mm The holes are located 8(±0.1) mm away from the center of the window and form a straight line with the center Deviation of the center of the hole from the straight line ±0.1 mm - 20 pieces Including transport.
