Quartz Glass Windows CNC Machined Irregular Fused Silica Plates for
Optical and Laser Systems
Overview
Customized fused silica optical windows in irregular formats are
designed to meet specialized mechanical and optical demands. These
non-standard shapes—ranging from arcs and ovals to complex patterns
with through-holes—are widely adopted in devices where integration
flexibility, optical clarity, and extreme environmental resistance
are critical.
Crafted from premium synthetic quartz glass, these windows provide
exceptional resistance to thermal shock, UV degradation, and
chemical corrosion. Their ability to transmit light across a wide
spectral range while maintaining dimensional accuracy makes them
the ideal choice for engineers and designers building bespoke
optical assemblies.
Production Technology
Unlike standard optics, irregular-shaped windows require an
extended fabrication flow:
3D Design Interpretation
The customer’s design files are analyzed for optical and structural
feasibility. Finite element analysis may be applied for mechanical
integrity checks.
Precision Machining
High-speed CNC routers or ultra-fine waterjet cutters are used to
cut the basic shape, including internal radii, slots, and recesses.
Edge Finishing & Deburring
Laser-assisted deburring or mechanical sanding removes micro-cracks
and prepares the surface for safe handling and coating adhesion.
Optical Finishing
Specialized polishing pads and slurry formulas are used to maintain
uniformity across irregular surfaces while minimizing waviness and
stress.
Inspection & Packaging
Dimensional gauges, optical interferometers, and UV-VIS
spectrometers ensure compliance with high-spec tolerances. Each
part is cleaned, packaged in foam or sealed pouches.

FAQ
Q1: What materials are available besides quartz?
A: While fused silica is most common, borosilicate or sapphire can
be offered for certain shapes or budgets.
Q2: Can I get anti-reflective coatings on curved surfaces?
A: Yes. Conformal AR coatings are available using multi-axis
deposition systems.
Q3: Are these products available in low volumes?
A: We support both prototype and mass production. MOQs can start as
low as 1 piece for R&D.
Q4: What is the lead time for irregular parts?
A: Typically 2–4 weeks depending on complexity, finishing, and
coating requirements.
Q5: How do I submit a custom design?
A: Simply send your technical drawings (2D or 3D format) and
application notes. We’ll respond with manufacturability advice and
a quote.
