D 263® M
Coverglass D 263® M
for flawless microscopy
|
D 263® M cover glass is a colorless borosilicate glass with a very low iron content. Its composition assures excellent resistance to chemical attack. D 263® M meets the requirements laid down in ISO 8255-1.
The outstanding features of D 263® M include:
|
Virtually colorless appearance
Excellent internal glass quality with very low levels of inclusions, striae, bubbles, streaks, etc.
High spectral transmission
Exceptional cutting and grinding characteristics
Excellent flatness
Optimum resistance to chemical attack
Refractive index finely adapted to microscopes
|
D 263® M is used as coverglass in microscopy for medical, biological and research work.
Spectral transmittance (d=0.15 mm)
|
Between 0.15 und 0.40 mm glass thicknesses, the light transmittance is τVA = 91.8%. In the visible range of the spectrum D 263® M is without absorption. The excellent UV absorption properties make D 263® M an ideal material for use in fluorescence microscopy.

All data are subject to change.
1)The accuracy of measurement for the thickness is ± 5 μm
2)For trimmed glass (without the bead), flatness is measured net width x length. The maximum deviation of the height at any point on the total surface of the glass panel is measured from an ideal plane surface. The determined maximum value is the index for the flatness deviation. It does not, however, include the nominal thickness of the glass panel.
