Customized cover glass is a high-quality, ultra-flat glass sheet specifically designed for optical, biomedical, and precision imaging applications. Manufactured in various dimensions and thicknesses (typically from 0.1 mm to 0.5 mm), it ensures exceptional transparency, low autofluorescence, and chemical resistance. Tailored options include anti-reflective coatings, hydrophilic/hydrophobic surfaces, and laser-cut shapes or holes. Perfect for microscopy, cell imaging, and diagnostic devices, our custom cover glass provides reliable performance in demanding laboratory and industrial environments.
