In high-temperature industrial equipment, precision optical instruments, chemical reaction devices, and laser equipment, a transparent accessory that can withstand extreme temperatures, resist corrosion, and achieve full spectrum high transparency is indispensable. The circular polished quartz glass sheet in the picture is the core optical transparent component that is suitable for various harsh working conditions. With high-purity silica substrate and precision polishing technology, it has become a standard window material for industrial, scientific research, and optoelectronic industries.
一、 Substrate material: high-purity quartz, with performance far superior to ordinary glass
The round transparent sheet is made of fused silica glass, which is divided into three main brands according to the use scenarios, covering the full spectrum use needs:
JGS1 ultraviolet quartz glass, with outstanding transmittance in the ultraviolet band, is suitable for ultraviolet detection, ultraviolet light sources, and ultraviolet experimental equipment; JGS2 ordinary optical quartz glass, which combines visible light and near-infrared transmittance performance, has the best cost-effectiveness and is a universal choice for industrial mirrors and conventional optical windows; JGS3 infrared quartz glass, specially designed for infrared spectroscopy equipment, with extremely low infrared light loss.
Different from ordinary glass and borosilicate glass in daily life, quartz glass has a purity of over 99.99% for silicon dioxide. It avoids defects such as impurity bubbles, light transmission and fogging, and high-temperature softening from the root, and has significant inherent performance advantages.
二、 Five core characteristics, suitable for various extreme working conditions
1，Super strong temperature resistance, not easy to explode in sudden changes of heat and cold
Quartz glass has a softening temperature of up to 1730 ℃ and can work stably in high temperature environments ranging from 800 ℃ to 1100 ℃ for a long time. It can withstand temperatures above 1200 ℃ in a short period of time. The extremely low coefficient of thermal expansion endows it with excellent thermal shock resistance, and it is not easy to crack even when directly in contact with normal temperature liquids at high temperatures. It is perfectly suitable for high-temperature scenarios such as boilers, high-temperature tube furnaces, and heat treatment equipment.
2，Wide spectrum, high transparency, outstanding optical accuracy
The product has undergone double-sided high-precision optical polishing treatment, with high surface flatness and no scratches or pitting. The light transmission range covers the full spectrum of ultraviolet, visible light, and near-infrared, with low light transmission loss and no color difference or scattering. It can be used as a protective window for laser equipment, as well as an optical path substrate for spectrometers, microscopes, and optical detection instruments.
3，Strong corrosion resistance, stable and durable chemical environment
Chemical inertness is extremely strong and does not react with strong acids, strong bases, or various organic solvents. Long term immersion in chemical liquids will not dissolve or atomize. Widely used as an observation mirror for reaction vessels, chemical pipelines, and pressure vessels, it maintains transparency and clarity even in long-term contact with corrosive media, significantly reducing the frequency of equipment component replacement.
4，Low insulation loss, suitable for optoelectronic laser scenes
The material itself has excellent insulation performance, does not conduct electricity at high temperatures, and has minimal thermal deformation. Long term high-temperature operation will not cause lens deformation or optical path deviation. In fiber optic, laser cutting, UV curing lamps, and xenon lamp light source equipment.
5，Flexible size and craftsmanship, supporting personalized customization
The standard finished product is a regular circular shape with precision chamfered edges, making it less likely to break or scratch during installation; Simultaneously supporting full specification customization: diameters ranging from 5mm to 300mm and thicknesses of 1-20mm can be processed as needed. Square, irregular, slotted, and perforated styles can also be made. The surface can be coated with anti reflective film, insulation film, or single-sided frosted treatment as needed to meet different equipment installation and optical requirements.
三 、 Diversified application scenarios, covering all fields of industry and scientific research。
Industrial high-temperature sight glass: Observation lenses for boilers, steam pipelines, high-temperature reactors, furnaces, and pressure vessels to observe internal working conditions in real time;
Laser optoelectronic industry: laser cutting machines, marking machine protective windows, UV curing equipment transparent sheets, various xenon lamps, mercury lamp shades;
Precision optical instruments: spectrometers, ultraviolet detectors, microscope slides, optical experimental substrates;
Laboratory research consumables: high-temperature crucible cover plate, UV transparent experimental slide, high-temperature reaction observation slide;
New energy and special equipment: photovoltaic testing equipment, high-temperature coating machine, battery high-temperature testing chamber observation window.
