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 objectives have been designed especially for qualitative and quantitative analysis of ion movements and for particularly critical fluorescence methods (e.g. chromosome studies in human and cytogenetics). These objectives are distinguished by high numerical apertures and highest transmission at wavelengths even of 340 nm. Field flattening is sufficient up to a field of 20 mm.
