Quartz glass has outstanding optical properties such as light transmission and has characteristics such as high purity high resistance to heat and radiation. 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.
Shin-Etsu Quartz manufacture and sell the SUPRASIL-P Series of ultra-high purity and excellent homogenous synthetic quartz glass and SUPRASIL-F300 an OH free synthetic.
Quartz glass uv transmission. For letting more customers learn about the material of the ultraviolet lamp here is a simple explanation. Pure quartz does not filter UV so there is a risk of UV exposure from halogen bulbs. In high refractive index glasses the UV edge ofthe transmittance curve is shifted to.
Ordinary glass is not transparent to germicidal ultraviolet radiation wavelengthsquartz is. How much light goes through the material rather than being absorbed by the material is directly affected by the impurity levels within the Quartz Glass. The enormous operating temperature range and the high thermal load capacity of quartz glass are unparalleled.
Greater thicknesses of glass implied less radiation transmitted but without a. Principle transmission at 10mm thickness considering natural surface reflection losses. In order to provide disinfection CRYSTAL CLEAR Quartz Sleeves allow precisely the right amount of radiation to pass through into the air or water.
280 400 nm. PeripherT of a cylinder of Heraeus fused quartz sample C approximately 4 in. The ordinary ultraviolet lamp tube is made of low-cost high-boron glass.
However fused quartz glass will allow practically UVA and UVB to pass through. Quartz glass is the basic material for the production of optical fiber because it has good UV transmission performance and very low absorption of visible light and near-infrared light. Laminated glass totally blocked UVA radiation while smooth ordinary glass transmitted the highest dose 743.
So depending on the application and the UV available a fused quartz glass vessel will allow UV to pass through. Quartz glasss optical properties are excellent and unlike other glasses this material continues to transmit into the UV range. Glass blocks UVB and partially UVA.

In quartz glass the homogeneity is typically specified in. And high-boron glasss ultraviolet-transmitting performance is not very good which causes the ultraviolet ray. One such glass is known as VYCOR which is 96 silica.
Quartz Glass for Optics Data and Properties 3D material optically isotropic. This also means that different absorbants can be deliberately introduced to block specific wavelengths. Why should I use a CRYSTAL CLEAR Quartz Sleeves for my UV lamp.
Since quartz is made of silicon dioxide glasses made from a high proportion of this material will also readily transmit UV. The curve above shows the typical optical transmission of our UV-grade quartz glass at 100 mm glass thickness for wavelengths from 160 – 5000 nm. Sometimes the lights are made using special high-temperature glass which at least filters UVB or doped quartz to block UV.
However remember that the shortest UV is the most damaging to the skin and cells. Quartz will transmit UV from 180 nm to 400 nm. We believe you will be satisfied with our reasonable price.
Quartz glass is also much more thermally stable and resistant to thermal shock than softer glass. Glass has a good transmittance in the blue and near UV region the dispersion of the glass in the visible the slope of the nλ curve is very low. The most important optical properties for this wavelength region are high transmission and excellent purity no fluorescence outstanding damage.
This is valid for low refractive index glasses. Sometimes halogen bulbs are encased inside glass. Fused quartz is very efficient for the transmission of infrared radiation.
Infrared transmission extends out approximately 4 micrometers with little absorption in the water band at 273µm. It is known to have eXLremely good ultraviolet transmission character istics but has a stronger absorption band around 26 J1. Request a quote for UV-Grade Optical Quartz Glass.
The seventh sample was made available by the Coming Glass vVorks. Besides the thermal expansion coefficient of quartz glass is extremely small. Next the radiation from the same sources was measured at the same distances but transmitted by different types of glass.
The baseline values were compared with the results after protection using glass. Long and 2 in.
