Cover Slip

Two-part boxes containing 100 pieces, 10 boxes per pack. High-precision cover glasses with thickness No. 1.5H featuring an exceptionally accurate thickness of 170 ?m ± 5 ?m. 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 

SPECIFICATIONS

Modern high-performance microscope objectives are designed to be used with cover glasses of a thickness of 170 ?m. 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.
