ANTGLASS manufactures optical filter glass components for UV, visible and infrared spectral control in cameras, sensors, analytical instruments, lighting and laser systems.
ANTGLASS produces absorptive filter-glass parts and coating-ready filter substrates with drawing-defined spectral, thickness, clear-aperture, edge, coating and cleanliness requirements.

ANTGLASS Manufacturing Capabilities
ANTGLASS provides precision cutting, CNC contour machining, drilling, slotting, notching, chamfering, grinding, lapping, polishing, coating-compatible handling, ultrasonic cleaning and protected packaging. The manufacturing sequence is selected around the coated, optical, via, chamber or angular features that control the finished component.
- Review spectral curve, filter grade and operating condition
- Select thickness from the optical and mechanical requirement
- Cut, machine, grind and polish the component geometry
- Coordinate coating-ready cleaning or approved coating requirements
- Inspect spectral, dimensional, surface and cosmetic criteria
Inspection, Cleaning and Packaging
Inspection is tied to the drawing and functional zones rather than a generic cosmetic check. Mechanical, optical, electrical or fluidic requirements are separated so the correct method and datum are used. Finished parts are cleaned and separated to protect critical faces, bores, coatings and edges.
- Filter grade and thickness traceability
- Spectral criterion and measurement condition
- Clear aperture, surface quality and coating zones
- Edge chips, scratches, cleanliness and orientation
Typical Applications
- Camera, imaging and machine-vision filters
- UV and IR detection systems
- Analytical and spectroscopy instruments
- Lighting, laser and thermal-control assemblies
Optical Filter Glass Components Design and Ordering Guide
Start the RFQ with the functional requirement and the measurement condition. A sheet-resistance value without a test position, a spectral value without wavelength and angle, or a geometric tolerance without a datum can produce conflicting interpretations. Mark all active, optical, conductive, sealing and contact zones directly on the drawing.
Separate critical requirements from general dimensions. ANTGLASS can then choose a stable process sequence, protect finished surfaces and use inspection methods that match the component function. For prototype work, identify which values are development targets and which are release criteria for repeat production.
- Identify the functional face and orientation datum.
- Define the clear, active or conductive area separately from the mechanical outline.
- State the inspection method or reference condition for critical values.
- Show protected edge zones, contacts, ports, coating masks or via exclusions.
- Include operating temperature, chemicals, optical band and assembly conditions.

Frequently Asked Questions
What is optical filter glass?
Optical filter glass is a material or coated component that transmits selected wavelengths and attenuates others. Its performance depends on grade, thickness, spectral test condition, angle of incidence and any coating stack.
What is the difference between absorptive filter glass and a coated filter?
Absorptive filter glass controls the spectrum through the bulk material, while a coated filter uses thin-film layers on a substrate. Some components combine both approaches to meet blocking, transmission and durability requirements.
Why must filter thickness be specified?
For absorptive filter glass, spectral transmission and blocking change with thickness. Thickness also affects mechanical fit, optical path and edge strength, so the drawing and spectral requirement must use the same nominal thickness.
Can ANTGLASS manufacture custom filter shapes and apertures?
Yes. ANTGLASS produces round, rectangular and custom filter components with holes, slots, notches, chamfers, polished edges, clear apertures and coating masks from customer drawings.
Which information is required for a filter quotation?
Provide the spectral curve or pass and block bands, material grade, thickness, angle of incidence, polarization where relevant, clear aperture, coating, surface quality, dimensions, quantity and inspection method.
