Product Description

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.

Marienfeld 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 applications according to EU regulation 2017/746 on in vitro diagnostic medical devices (IVDR), with CE-mark and batch number for comprehensive information and traceability
