Product Description
Cover Glass 18mm Diameter No 1.5H – High-Precision Microscope Cover Glass for Optimal Imaging
Modern high-performance microscope objectives are designed for use with cover glasses of 170 μm thickness. The quality and precision of the cover glass — especially its strict adherence to the nominal thickness — play a crucial role in achieving sharp, high-contrast images. Any variation in thickness can lower image contrast and introduce optical defects, particularly spherical aberration.
Our Cover glass 18mm Diameter No 1.5H are engineered to meet these demanding requirements. They feature an exceptionally accurate thickness of 170 μm ± 5 μm, making them the ideal choice for high-resolution microscopy. These premium cover glasses are specifically recommended for use with objectives that have a high numerical aperture, including:
-
Dry objectives: N.A. > 0.7
-
Water immersion objectives: N.A. > 1.0
-
Glycerol immersion objectives: N.A. > 1.2
-
Oil immersion objectives: N.A. > 1.3
