Custom processing

Full Customization Technical Capabilities

Felix Glass supports drawing-based fused silica plate processing for dimensional, edge, hole, and optical surface requirements.

Maximum Plate Size

Large-format quartz plates are selected by raw material grade, plate thickness, and flatness requirement.

Minimum Thickness

Thin quartz sheets can be processed for UV windows, wafers, and precision instrument substrates.

Thickness Tolerance

Controlled grinding and inspection keep custom fused silica plate thickness aligned with assembly drawings.

Surface Flatness

Flatness is specified according to optical path, sealing surface, and thermal load conditions.

Surface Roughness

Surface roughness is matched to transparency, sealing, cleaning, and contact requirements.

Arbitrary Hole Drilling

Round holes, slots, countersinks, and mounting features can be processed by CNC and fixture methods.

Edge Chamfer & Polishing

Chamfering reduces edge stress concentration during handling, heating, and installation.

Optical Polishing Grade

Single-sided or double-sided optical polishing is available for UV and inspection windows.

Procurement questions

Engineering Custom FAQ

Answers are written for buyers comparing fused silica plate options by UV grade, heat resistance, machining difficulty, and documentation requirements.

How are UV transmittance grades separated?

Material grade, thickness, polishing quality, and wavelength range are reviewed together. UV transparent quartz sheet projects should define the working band before quoting.

How can cold-heat cracking risk be reduced?

Use suitable fused quartz grade, avoid sharp inside corners, add chamfers, control thermal ramp rate, and apply annealing when the design carries high stress.

What is the minimum machinable thickness?

Minimum thickness depends on plate size, hole layout, edge design, and polishing requirement. Thin substrates are evaluated with fixture support before production.

Does high temperature use require coating?

Many high temperature resistant quartz glass applications use uncoated surfaces. Coating is considered only when reflection control, contamination control, or a defined optical function is required.

What is the normal lead time for quartz plates?

Lead time depends on material availability, size, tolerance, hole drilling, optical polishing, and inspection documents. Drawing-based quotation confirms the schedule.

Can third-party optical test reports be supplied?

Third-party or project-specific optical inspection reports can be arranged when UV transmittance, flatness, roughness, or dimensional records are required.
