Grooved Precision Glass Fused Silica Plate 150x5x3mm Groove Width 2.5mm Optical Testing

The Grooved Precision Glass Plate is a machined optical glass component with an overall dimension of 150 x 5 x 3mm and a precision groove width of 2.5mm, designed for positioning and carrying components in optical testing systems. The groove is machined to uniform depth along its length, providing stable seating for samples, fibers and small optical elements. The plate surface is clean, polished and scratch-free, offering even light transmittance and a smooth contact area that protects workpieces from damage. Manufactured from chemically stable precision glass, the plate delivers outstanding chemical stability and wear resistance, maintaining its dimensional accuracy and optical clarity through repeated use in laboratory and inspection environments.

• Uniform groove depth: The groove is machined to consistent depth and geometry, ensuring stable seating and accurate positioning of samples and components.
• Clean scratch-free polished surface: The polished face is smooth and defect-free, protecting delicate workpieces from marks and damage during handling.
• Even light transmittance: The clear glass body transmits light uniformly, supporting reliable performance in optical testing and spectrum instruments.
• Outstanding chemical stability: The material resists common laboratory reagents and cleaning agents, keeping the plate clean and durable in service.
• High overall flatness: The precisely finished plate provides a level reference surface that supports stable and repeatable measurements.

The Grooved Precision Glass Plate is designed for optical and laboratory systems that require precise, stable placement of small components. It is commonly used in optical testing equipment as a carrier that holds lenses, filters and test pieces in a fixed position during measurement. In analytical workflows, the plate serves as a micro sample carrier, providing a clean and inert platform for handling small quantities of material without contamination. The component is also adopted in spectrum instruments as a precision part, where its uniform transmittance and stable geometry support consistent spectral readings. Additionally, the plate functions as a laboratory optical base, forming a reliable foundation for building and aligning experimental optical paths with repeatable accuracy.

• Tight dimensional tolerance for grooves: Groove width and depth are controlled within narrow limits, guaranteeing consistent seating and reliable positioning of components.
• High overall flatness: The precisely ground and polished surface delivers a level reference that keeps measurement geometry stable and repeatable.
• Wear-resistant and scratch-proof: The durable polished finish resists wear and avoids scratching test components during loading, unloading and repeated use.
