Precision cover glasses thickness No. 1.5H (tol. ± 5 μm) for high performance microscopes

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

 

  • made of chemically resistant borosilicate glass D 263® M of the first hydrolytic class
  • absolutely colourless, perfectly clear, suitable for fluorescence microscopy
  • in compliance with DIN ISO 8255
  • thickness No. 1.5H (0.170 mm ± 0.005 mm)
  • for in-vitro diagnostic (IVD) applications according to IVD directive 98/79/EC, with CE - mark and batch number for comprehensive information and traceability
