UV / IR Grade Quartz Through Hole Plates Custom Cut High Temperature Chemical
Detailed Diagram
Overview of Quartz Plate
Quartz plates with through-holes are engineered components fabricated from high-purity silica glass, available in custom dimensions and complex geometries. These shaped quartz substrates are designed to support high-performance applications in optics, microfluidics, vacuum systems, and high-temperature manufacturing.
The integrated holes allow for beam alignment, gas flow, fiber feedthroughs, or mounting functions. The plates are offered in various material types to match spectral and thermal needs.
JGS Grade Classification
We offer quartz glass sheets in three standardized grades—JGS1, JGS2, and JGS3—each optimized for different optical and industrial applications. Understanding the distinction between these grades helps ensure you select the right material for your specific use.
JGS1 – UV Optical Grade (Synthetic Quartz)
-
Transmission Range: 180–2500 nm
-
Highlights: Exceptional UV transmittance, ultra-high purity, low hydroxyl and metal content
-
Use Cases: UV lasers, lithography, precision optics, UV curing systems
-
Production: Flame hydrolysis of high-purity SiCl₄
-
Notes: Ideal for deep-UV and high-precision optical systems
JGS2 – IR & Visible Grade (Fused Quartz)
-
Transmission Range: 260–3500 nm
-
Highlights: Strong IR and visible light transmission, cost-effective, stable under heat
-
Use Cases: Infrared windows, IR sensors, furnace viewports, light guides
-
Production: Fusion of natural quartz crystal
-

JGS3 – Industrial Grade (General Quartz Glass)
-
Transmission Range: Transparent in visible and IR; blocks UV below 260 nm
-
Highlights: Excellent thermal resistance, high chemical durability, low cost
-
Use Cases: Semiconductor heating elements, chemical containers, lamp covers
-
Production: Fused quartz with industrial-level clarity
-
Notes: Best for structural and high-temperature industrial use

How They’re Made of Quartz Plate
Laser drilling is a high-precision, non-contact method used to create holes in fused quartz glass by focusing a concentrated laser beam on the material surface. The intense energy of the laser rapidly heats and vaporizes the quartz, forming clean holes without causing cracks or mechanical stress.
This technique is especially suitable for microholes (as small as 10 microns), high-density patterns, and fragile quartz components. Femtosecond or picosecond lasers are commonly used to minimize heat-affected zones and achieve smooth edges with excellent accuracy.
Laser drilling is widely applied in microfluidics, semiconductors, optics, and advanced scientific instruments that require precision and reliability.
