Through-hole transparent sapphire components are precision-engineered optical and structural parts made from single-crystal aluminum oxide (Al₂O₃). Featuring excellent optical clarity and unmatched mechanical strength, these components combine transparency, hardness, and chemical resistance, making them ideal for demanding environments. The through-hole design allows for precise alignment, fluid passage, or mounting functions in optical, mechanical, and electronic assemblies.
Sapphire is second only to diamond in hardness, with a Mohs rating of 9, ensuring exceptional wear resistance and durability. Its high transmittance from ultraviolet (UV) to infrared (IR) wavelengths and excellent thermal conductivity make transparent sapphire a preferred material for high-performance optical and mechanical systems.
High Optical Clarity: Excellent transmission range from 200 nm to 5000 nm, suitable for UV, visible, and IR applications.
Extreme Hardness: Mohs 9 hardness provides outstanding scratch and abrasion resistance.
High Strength and Stability: Maintains optical and mechanical integrity under high temperature and pressure.
Chemical Inertness: Resistant to acids, alkalis, and plasma environments.
Precision Machining: Through-holes can be made via laser drilling, ultrasonic machining, or diamond grinding with micrometer-level tolerance.
Wide Operating Temperature: Stable from −180°C up to 2000°C in vacuum or inert atmospheres.
Optical Systems:
Used in optical windows, lenses, or housings that require light transmission and through-hole alignment for mechanical or photonic integration.
Semiconductor Equipment:
Serves as observation windows, wafer holders, or insulating supports where transparency and heat resistance are critical.
Aerospace and Defense:
Integrated into sensors, infrared domes, and laser targeting systems where durability and optical clarity are required.
Medical and Analytical Instruments:
Suitable for spectroscopic cells, flow-through cuvettes, or pressure-resistant sample chambers.
Industrial and Precision Machinery:
Used in wear-resistant guides, bushings, and alignment fixtures where through-holes facilitate assembly or fluid passage.

Q1: What is the main advantage of through-hole sapphire compared with glass or quartz?
A1: Sapphire offers much higher hardness, temperature resistance, and chemical durability than glass or quartz, making it suitable for extreme conditions and high-precision optical assemblies.
Q2: Can through-holes be made very small?
A2: Yes. With laser or ultrasonic drilling, through-holes as small as 0.1 mm can be achieved with tight tolerance and minimal microcracking.
Q3: Is anti-reflective coating available?
A3: Yes. AR coatings or metallized layers can be applied according to wavelength and application requirements.
Q4: What shapes are available?
A4: Round, square, rectangular, and irregular custom geometries are all available. Multi-hole or counterbore designs can also be produced.
