Q: Why choose quartz rods for optical instruments?  

Answer: Quartz rods have extremely high ultraviolet infrared transmittance, excellent thermal stability, and corrosion resistance, which can significantly improve the accuracy, durability, and signal-to-noise ratio of optical instruments, especially suitable for high-precision sensing, laser systems, and optical components in harsh environments.

Q: What core problems can quartz rods solve?  

Answer:

1. Environmental interference: Resist high temperature, corrosion, and UV aging, and maintain long-term stability.  

2. Optical loss: Low refractive index and high transmittance reduce optical signal loss and improve detection sensitivity.  

3. Customization requirements: Flexibly adapt to the size, shape, and coating requirements of different instruments to shorten the research and development cycle.  

The core application of quartz rods in optical instruments

quartz rod (quartz glass rod) is widely used in:

-Laser optical system: As a light guide rod and resonant cavity component, it is resistant to high-intensity laser radiation.  

-Spectrometer and sensor: UV infrared broadband transmission ensures the accuracy of detection data.  

-High temperature window and observation device: with a heat resistance of over 1100 ℃, suitable for industrial monitoring and scientific research equipment.  

-Fiber coupling and collimation components: low thermal expansion coefficient (5.5 × 10 ⁻⁷/℃) to avoid optical path deviation caused by temperature deformation.  

Product advantage: Why is quartz rod superior to ordinary optical materials?  

1. Excellent optical performance

-The average transmittance in the ultraviolet (185nm) to infrared (2.5 μ m) wavelength range is greater than 92%, with no stray light interference.  

-Low fluorescence characteristics, avoiding background noise, and improving signal-to-noise ratio.  

2. Strong physical and chemical stability

-The coefficient of thermal expansion is only 1/15 of that of ordinary glass, and it can withstand rapid cooling and heating impacts.  

-Acid resistant (except hydrofluoric acid), moisture-proof, and extend lifespan by 3-5 times in corrosive environments.  

3. Strong customization flexibility

-Support customized specifications with diameters ranging from 0.5mm to 200mm and lengths ranging from 10mm to 2000mm.  

-It can be processed for secondary processing such as polishing, inclined cutting, anti reflective coating (AR), and metallization treatment.  

Customized Services: Matching Differentiated Needs of Global Customers

-Size customization: Based on the optical design drawings, precisely control the tolerance (diameter ± 0.01mm).  

-Surface treatment: Provides optical grade polishing (Ra<1nm), matte, frosted and other treatments.  

-Coating process: UV enhanced, infrared enhanced, hydrophobic and anti fouling coating, suitable for specific wavelength requirements.  

-Material selection: Choose JGS1 (UV grade), JGS2 (infrared grade), or synthetic quartz (low OH content).
