Quartz Slides & Quartz Coverslips from CRAIC Technologies™
CRAIC Technologies quartz slides and coverslips are spectral grade and manufactured to the highest levels of quality.
Quartz slides and coverslips are essential for UV-visible microspectroscopy and microscopy because they transmit UV light far more efficiently than common glass slides and coverslips, which absorb UV light and transmit very little below 340 nm.
However, not all quartz is created equal. There are various grades and specifications, and most commercially available quartz slides and coverslips use lower-grade materials unsuitable for deep UV microspectroscopy or microscopy. For spectroscopists, maximizing UV light transmission is crucial, especially in the deep ultraviolet region where many materials exhibit unique features.
Consider the transmittance spectra of CRAIC spectral grade quartz compared to commonly used quartz in microscope slides and coverslips. The purple line represents the lower-grade quartz typically used in standard slides and coverslips, showing a significant drop in UV transmission below 265 nm. This drop is why many scientists struggle with UV microspectroscopy between 200 to 265 nm when not using CRAIC quartz slides. In contrast, the red line represents the optical-grade quartz used by CRAIC Technologies in their slides and coverslips, which transmits over 85% of UV light down to 200 nm.
By choosing CRAIC quartz slides and coverslips, scientists ensure high UV light transmission, enabling accurate and efficient UV microspectroscopy and microscopy, even in the challenging deep ultraviolet region.
