Coverslips #1.5H 24x50mm, 100 pieces per box, 10 boxes per pack, (1000 pieces)
Modern high-performance microscope objectives are designed to be used with cover glasses of a thickness of 170 μm. The quality of the cover glass, in particular the compliance with the nominal thickness, has thereby a crucial impact on the imaging quality. Variations of thickness reduce the image contrast and result in image defects, most notably in spherical aberration.
High-precision cover glasses with thickness No. 1.5H featuring an exceptionally accurate thickness of 170 μm ± 5 μm. This new generation of cover glasses are highly recommended for objectives with high numerical aperture and high resolution, for example:
- dry objectives: N.A. > 0.7
- objectives for water immersion: N.A. > 1.0
- objectives for glycerol immersion: N.A. > 1.2
- objectives for oil immersion: N.A. > 1.3
