ANTGLASS manufactures custom optical glass prisms for beam deviation, reflection, image rotation, dispersion, spectroscopy and optical instrument assemblies.
ANTGLASS produces prisms in N-BK7, fused silica and specialty optical glass with controlled face angles, flatness, clear apertures, polished surfaces, edges and coatings.

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 prism type, ray path and face-angle definition
- Select optical glass and prepare the prism blank
- Generate faces, angles and edge geometry
- Lap and polish the defined optical surfaces
- Clean, coat where specified and inspect optical performance
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.
- Face angles and dimensional geometry
- Surface flatness, quality and clear aperture
- Coating, reflectivity or transmission zones
- Beam deviation, orientation and cosmetic condition
Typical Applications
- Beam steering and folding
- Spectroscopy and wavelength dispersion
- Image rotation and erecting systems
- Laser, imaging and analytical instruments
Optical Glass Prisms 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
Which types of optical prisms can ANTGLASS manufacture?
ANTGLASS manufactures right-angle, equilateral, dispersing, Dove, roof, penta, wedge and custom prisms from customer drawings for beam steering, reflection, dispersion and image rotation.
Which materials are used for optical prisms?
N-BK7 is widely used for visible systems, fused silica supports UV, laser and low-expansion applications, and high-index flint or specialty glasses support compact deviation and dispersion designs.
Which prism tolerances should be shown on the drawing?
Specify face dimensions, face-angle tolerances, flatness, surface quality, clear aperture, chamfers, coating zones, reference orientation and the required beam-deviation or transmitted-wavefront result.
Can prism faces receive optical coatings?
Yes. Prism faces can be prepared for antireflection, mirror, beamsplitter or other approved coatings. The drawing should identify each face, coating function, wavelength, angle of incidence and protected edge zone.
How are optical prisms inspected?
Inspection can include dimensions, face angles, flatness, surface quality, clear aperture, coating zones and beam deviation or orientation. The inspection method is matched to the optical function and drawing.
