This is the general-purpose flat quartz product — clear fused quartz cut to size, without the optical-grade spectral requirement (see Optical Quartz Plates & Windows), the large-format engineering (see Large Quartz Plates & Slabs), or a specific round/perforated/curved geometry covered on their own pages.
Dimensions & Tolerance
| Parameter | Range |
|---|---|
| Length × Width | Per drawing |
| Thickness | Per drawing |
| Flatness | Per drawing, tighter for polished-finish product |
Thickness tolerance (by thickness band):
| Thickness | Tolerance |
|---|---|
| >2 – 50 mm | ±0.10 – 0.15 mm |
| >50 – 100 mm | ±0.15 – 0.30 mm |
| >100 – 200 mm | ±0.30 – 0.50 mm |
Length/width tolerance (by size band):
| Dimension | Tolerance |
|---|---|
| ≤50 mm | ±0.05 – 0.10 mm |
| >50 – 100 mm | ±0.10 – 0.20 mm |
| >100 – 200 mm | ±0.20 – 0.50 mm |
Chamfer: ±0.10 – 0.30 mm. Arc/angle: 1° – 3°.
Surface Finish
- Polished — smooth, optical-adjacent finish for general clarity
- Frosted / ground — matte finish where diffusion or a non-glare surface is preferred
- As-cut — unfinished edge, lowest cost
Material
Clear fused quartz, standard grade — see Quartz Glass Tubes Material Grades for the Type I–IV / JGS1–3 comparison if a specific transmission or OH-content requirement applies (route to Optical Quartz Plates & Windows for that case).
FAQ
What’s the difference between this page and Optical Quartz Plates & Windows?
This page is general clear fused quartz cut to size with no specific spectral transmission requirement. Optical Quartz Plates & Windows covers material selected by JGS grade for a defined UV/visible/IR transmission range.
Can plates be supplied with a frosted finish on one side only?
Yes, per drawing — specify which face gets which finish.
What’s the largest size available on this page?
Standard cutting covers most general sizes up to roughly 200mm per side within the tolerance table above; for larger format, see Large Quartz Plates & Slabs.
