ConductScience Cover Slips 22x22mm, No. 1.5 are precision glass coverslips designed for high-resolution microscopy applications. With a thickness of 0.16-0.19mm (No. 1.5), these coverslips provide optimal optical performance for confocal and fluorescence imaging by minimizing spherical aberration and maximizing numerical aperture efficiency.
The 22x22mm dimensions accommodate standard microscope slide preparations while providing sufficient sample area for most cellular and tissue imaging protocols. The No. 1.5 thickness specification ensures compatibility with high-magnification oil immersion objectives and advanced imaging techniques requiring precise working distances.
How It Works
Glass coverslips function as optical interfaces that protect specimens while maintaining high-quality light transmission for microscopy. The No. 1.5 thickness (0.16-0.19mm) is specifically engineered to match the working distance requirements of high-numerical-aperture objectives, particularly those designed for oil immersion.
When light passes through the specimen and coverslip, the precise thickness minimizes spherical aberration that would otherwise degrade image quality. The glass composition provides uniform refractive index properties, ensuring consistent optical performance across the entire coverslip surface.
During imaging, the coverslip serves as a mechanical barrier protecting the objective lens from direct contact with mounting medium or specimen, while its optical properties become part of the imaging system's design parameters for optimal resolution and contrast.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Thickness Specification | No. 1.5 (0.16-0.19mm) | Entry-level coverslips often use No. 1 thickness | Better compatibility with high-magnification objectives designed for No. 1.5 specifications |
| Size Format | 22x22mm square | Round or rectangular formats vary by supplier | Standard square format maximizes sample area while fitting conventional slide dimensions |
| Material Quality | Precision glass construction | Some alternatives use plastic substrates | Glass provides superior optical clarity and chemical resistance for demanding applications |
| Imaging Optimization | Optimized for confocal imaging | Basic coverslips may not specify optical optimization | Engineered thickness reduces spherical aberration in advanced imaging techniques |
These coverslips offer precision No. 1.5 thickness specification in a standard 22x22mm format with glass construction optimized for confocal and high-resolution microscopy. The thickness specification ensures compatibility with advanced imaging objectives requiring precise working distances.
Practical Tips
Lower coverslips at a 45-degree angle to minimize air bubble formation during mounting.
Why: Air bubbles interfere with imaging and can create optical artifacts.
Store coverslips in original packaging to prevent dust accumulation and mechanical damage.
Why: Contamination and scratches degrade optical performance and image quality.
Use appropriate mounting medium volume to avoid excess that extends beyond coverslip edges.
Why: Excess medium can interfere with objective positioning and create imaging artifacts.
Handle coverslips by edges to avoid fingerprints on optical surfaces.
Why: Fingerprint oils create optical distortions and can be difficult to remove completely.
Verify thickness specification matches your objective lens requirements before purchasing.
Why: Mismatched coverslip thickness creates spherical aberration and reduces image resolution.
Allow mounting medium to fully set before imaging to prevent specimen drift.
Why: Incompletely set medium can cause focal plane shifts during extended imaging sessions.

Compliance
What is the refractive index of these coverslips?
Standard borosilicate glass coverslips typically have a refractive index of approximately 1.52. Consult product datasheet for specific optical properties.
Can these coverslips be autoclaved for sterile applications?
Glass coverslips generally withstand autoclaving temperatures. However, verify sterility requirements and thermal stress limits for your specific application.
Are these coverslips compatible with oil immersion objectives?
Yes, the No. 1.5 thickness (0.16-0.19mm) is specifically designed for high-magnification oil immersion objectives and confocal microscopy.
What mounting media work best with these coverslips?
Compatible with standard aqueous and organic mounting media. Choose mounting medium based on specimen requirements and imaging duration.
How should unused coverslips be stored?
Store in original packaging in a clean, dry environment to prevent contamination and mechanical damage.
Can these coverslips be cleaned and reused?
While possible, reuse is generally not recommended for critical applications due to potential optical degradation and contamination risks.
What is the difference between No. 1 and No. 1.5 coverslips?
No. 1.5 (0.16-0.19mm) is thicker than No. 1 (0.13-0.16mm) and provides better optical performance for high-magnification and confocal imaging applications.
