Comments and conditions

Glass objective slide (Marienfeld, 7.5 cm x 2.5 cm, 1 mm thick). "Tin" side of the float glass. Float glass is produced by pouring molten glass onto liquid tin, so that the glass floats on top of the liquid tin while it cools down forming very flat sheets. Some tin diffuses into the glass surface facing the tin bath during the cooling procedure. This side of the glass, the "tin" side, receives different surface optical properties compared to the other side, the "air" side."
