Item no.: 474030-9000-000Cover glasses, high performance, D=0.17mm, box with 1000 pc. Size 18x18 mm² type 1 1/2 H as per ISO 8255-1 with restricted thickness-related tolerance D=0.17 mm +/- 0.005 mm refractive index = 1.5255 +/- 0.0015, Abbe number = 56 +/-2 recommended for applications with high numerical aperture objectives
Note:
All measures in [mm]
mech. Arbeitsabstand = mechanical working distance
Deckglas = cover glass
Objektebene = object plane
Objektfeld = object field
Ausleuchtung = illumination
Probenzugänglichkeit = specimen accessibility

Note:
Please note that due to production tolerances, the given values are typical only and not guaranteed.

These are objectives for transmitted-light routine microscopy and epi-fluorescence microscopy with visible-light excitation. Thanks to their excellent image flatness across visual field diameters of 23 mm, these objectives are ideal for photomicrography in routine microscopy.
