What is optical grade quartz?
Optical Quartz Glass is Synthetic Fused Silica Quartz glass for optics bases on high-purity synthetic quartz called fused silica, produced by a flame hydrolysis process. Only such unique quartz glass qualities offer this high transmission for deep UV-light, which is greater than 80% at a wavelength as low as 185 nm.
Is fused silica the same as quartz?
Fused Silica and Quartz are both extremely pure materials featuring very low thermal expansion and excellent optical qualities. The main difference between the two is that Fused Silica is composed of a non-crystalline silica glass, while Quartz is made from crystalline silica.
What is the difference between quartz and quartz glass?
As an amorphous substance, glass has a random molecular structure, while quartz has a symmetrical molecular structure. Both quartz and glass are utilized for electrical purposes; glass is an insulator, while quartz is a conductor.
What is IR transparent?
Most transparent plastics are infrared transmitting. These grades are opaque to visible light and allow infrared light through. Unlike glass, you can put all our IR grades in front of DVR’s, cable boxes, DVD players etc. and your remote control, wireless router etc. will still work.
Is quartz stronger than glass?
Quartz has a much higher melting onset than borosilicate. Since it can withstand higher temperatures this could be one contributing factor to the fallacy that quartz is stronger than glass. In conclusion, both fused quartz and borosilicate are glass and glass-ceramics.
Can you fused quartz?
These materials are manufactured through dissimilar processes at disparate costs, using different components, and have different properties. Fused quartz is processed by fusing powdered crystal quartz in a hydrogen-oxygen flame and is manufactured to various purity specifications, for several specific uses.
How do you tell the difference between quartz and crystal?
Glass is either perfectly clear or may show some bubbles. Clear Quartz is harder than glass so you can test it by trying to cut a piece of glass (something like a glass bottle) with the crystal. If it cuts the glass, then you know it is Quartz.
What kind of transmission occurs in quartz glass?
Transmission through UV quartz glass between 150 nm and 4500 nm. Made from JGS3 UV-grade fused silica, absorption onset occurs below 170 nm with exceptionally high transmission across UVB, UVA, visible, near IR, and notibly short IR. Transmission drops significantly in the mid IR, and at 4200 nm there is complete absorption.
What kind of transmittance does quartz cuvette have?
Our IR quartz cuvettes (which have high transmission between 260 nm and 3600 nm) offer excellent transmittance across the near-IR, short-IR, and mid-IR spectra. Please see below for detailed tables containing product specifications.
Which is better UV or IR quartz cuvettes?
The transmission spectra for our UV quartz cells can be seen below. When working in the IR spectra, especially for wavelengths greater than 2000 nm, we recommend IR Quartz Glass Cuvettes instead, as they offer high transmission for these wavelengths. Transmission through UV quartz glass between 150 nm and 4500 nm.
Are there any infrared absorption features of quartz?
Despite all the efforts, the fundamental infrared absorption features of α -quartz are still poorly constrained.
