Precision cover glasses thickness No. 1.5H (tol. ± 5 μm)

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.

We produce 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
