MUHWA JGS2 Fused Quartz Microscope Slides — Precision Optics for Advanced Microscopy
MUHWA JGS2 fused quartz microscope slides are engineered from high-purity synthetic fused silica, delivering exceptional optical performance across the UV, visible, and near-IR spectrum (0.19–4.2 µm). Unlike standard glass slides that absorb UV light and autofluoresce, JGS2 quartz provides superior transmission, minimal background signal, and thermal stability to 1250°C—making it the substrate of choice for fluorescence microscopy, UV spectroscopy, hot-stage analysis, and semiconductor inspection. Standard and custom dimensions are available to fit your specific instrument or application.
Key Features
- Broad Spectral Transparency: 0.19–4.2 µm range with very low absorbance in the critical 0.26–2.6 µm window.
- Ultra-Low Autofluorescence: Ideal for fluorescence microscopy, confocal imaging, and Raman spectroscopy where background signal must be minimized.
- Thermal Resistance: Continuous use at 1250°C; short-term exposure to 1400°C. Compatible with hot-stage microscopy and thermal processing.
- Chemical Durability: Resistant to most acids (except HF) and organic solvents; suitable for aggressive sample environments.
- High Surface Quality: Polished surfaces with low surface roughness for uniform sample mounting and imaging.
- Custom Dimensions: Standard slides in stock; custom thickness (0.5–3 mm), width, and length available on request.

FAQ
Q: What is the difference between JGS1 and JGS2 quartz?
JGS2 is synthetic fused silica produced by flame hydrolysis; it offers higher UV transmission and lower OH content compared to JGS1 (electric-fused quartz). For general UV microscopy, JGS2 is preferred.
Q: Can these slides be used with oil immersion?
Yes. Standard immersion oils are compatible. Clean with isopropanol or acetone after use.
Q: Do you offer anti-reflection coatings?
Custom AR coatings for specific wavelength ranges are available on request. Contact us with your requirements.
