What is Spectrosil?
What is Spectrosil?
Spectrosil is a chlorine and bubble free synthetic fused silica ideal for deep UV optical applications. It features exceptional optical transmission in the deep ultraviolet and visible spectrums with a range from below 180 nm through 2000 nm.
What is quartz glass used for?
Quartz glass is used in the manufacturing of optical devices, lighting systems, refractory materials, and chemical apparatuses.
What is Infrasil?
These 1.0 mm thick, uncoated windows are fabricated from Infrasil®†, a type of optical quartz. Infrasil is a popular alternative to UV fused silica since the two materials have nearly identical mechanical and optical properties. They are also too thin for standard setscrew-based optic mounts.
What is doped quartz?
The UV transmission properties of quartz can be modified by the incorporation of a dopant. This dopant is most often cerium or titanium oxides. This includes the elimination of ozone or the prevention of UV damage to Nd:YAG rods, reflectors, plastics and “O” rings. …
Where fused quartz is used?
Fused silica and quartz are used in the manufacture of many optical parts—such as lenses, mirrors, UV and IR transmitting optics, and metrology components—due to their ability to transmit light in the visible, ultraviolet, and infrared range.
Is quartz stronger than glass?
Quartz crystals are harder than glass. In 1812 German geologist Friedrich Mohs invented the hardness scale used for testing minerals and other materials. Glass ranks around 5.5 on the Mohs scale. Quartz crystals rank as 7 on the Mohs scale.
How is fused quartz made?
Fused quartz is produced by fusing (melting) high-purity silica sand, which consists of quartz crystals. Type II is produced by fusing quartz crystal powder in a high-temperature flame. Type III is produced by burning SiCl4 in a hydrogen-oxygen flame.
Why silica is used in glass?
(It is also called fused quartz if derived from the melting of quartz crystals.) Silica glass is used where high service temperature, very high thermal shock resistance, high chemical durability, very low electrical conductivity, and good ultraviolet transparency are desired.…
How do you know if a quartz is real?
Real Clear Quartz crystals will often feel cooler to the touch than glass. Glass will feel room temperature, while quartz will be slightly cooler in your hand. Leave your clear quartz crystal on the counter for a few hours and pick it up – what is the temperature? If it’s a bit cooler, it’s likely authentic!
Can quartz have bubbles?
Inspect the specimen for air bubbles. If air bubbles are present, it is glass, not quartz crystal. Quartz crystal may contain imperfections, but they are not perfectly round like air bubbles.
What is Spectrosil 2000?
Spectrosil® 2000 is a deep UV, fluorescence-free grade. Spectrosil® is a synthetic fused silica manufactured using a patented, environmentally friendly process that results in a virtually chlorine-free material of exceptional purity which is bubble-free and fluorescence-free.
What is the Spectronic 200?
The SPECTRONIC 200 is a rugged, simple-to-use spectrophotometer ideal for routine applications. On-board software, controlled from an intuitive navigation pad using a full color screen, delivers capabilities beyond expectations. With no moving parts, there’s nothing to wear out
How do I use the Thermo Scientific Spectronic 200 live display?
Thermo Scientific SPECTRONIC 200 User Guide 14 Use the arrow keys to select GO, then press ENTER to start the Live Display mode as shown in fig 5.2 Figure 5.2 The displayed %T/Abs value updates every 2 to 5 seconds (depending on wavelength).
How do I set the wavelength on my Spectronic 200?
W avelength knob: In SPECTRONIC 200 Modern and SPECTRONIC 20 Emulation modes, the user can set the wavelength by rotating the wavelength knob. Turning the knob without pressing down changes the wavelength in 10nm increments.
