90x18x3mm Precision Grooved Quartz Substrate High Purity Optical Plate

The Grooved Quartz Substrate is a precision machined high-purity quartz plate with an overall dimension of 90 x 18 x 3mm, featuring a precision groove machined to uniform depth across the working area. Manufactured from high purity fused quartz, the substrate offers a double-sided scratch-free polished surface that protects optical workpieces during handling and measurement. The combination of excellent flatness and tight groove machining tolerance makes the plate a dependable platform for positioning components in optical assemblies and high-temperature measurement systems. With strong thermal stability and resistance to acids and alkalis, this grooved substrate maintains its dimensional and optical integrity in demanding environments, delivering reliable performance for precision optical applications.

• Uniform groove depth: The precision groove is machined to consistent depth and geometry, ensuring stable seating and accurate positioning of workpieces.
• Double-sided scratch-free polished surface: Both faces are finished smooth and defect-free, protecting optical components and samples from damage.
• High temperature and acid-alkali resistance: The quartz body withstands elevated temperatures and aggressive cleaning agents without degradation.
• High purity without impurity precipitation: The clean material releases no contaminants, keeping optical surfaces and workpieces uncontaminated during use.
• Excellent flatness: The precisely finished plate provides a level reference surface that supports stable and repeatable measurements.

The Grooved Quartz Substrate is designed for optical and laboratory systems that require precise, stable placement of components under demanding conditions. It is commonly used as a positioning carrier for optical elements, where the precision groove holds lenses, filters or samples at a fixed location and orientation. In spectral testing and measurement setups, the substrate provides a clean, flat and chemically inert platform that will not interfere with optical signals. Thanks to its strong thermal stability, the plate is particularly suited to high-temperature optical applications, such as light source conditioning and thermal testing fixtures, where ordinary materials would deform or contaminate the optical path. The scratch-proof polished surface also makes it ideal for handling valuable workpieces that must remain free of marks and defects throughout inspection.

• Excellent flatness: The precisely ground and polished surface delivers a level reference that keeps measurement geometry stable and repeatable.
• Tight machining tolerance for grooves: Groove width and depth are controlled within narrow limits, guaranteeing consistent seating of components.
• Scratch-proof for workpieces: The smooth polished finish minimizes the risk of scratching lenses, mirrors and samples during loading and unloading.
• Strong thermal stability: The substrate maintains dimensional and optical integrity at high temperatures, making it well suited to high-temperature optical scenarios.
