Optical Lens Polishing Jig

Name: Optical Lens Polishing Jig | Lens Surface Finishing Fixture – Frigate
Price: 249.00 USD
Availability: InStock

Optical Lens Polishing Jig enables angular and axial alignment within ±2 arcseconds, minimizing decentration during high-speed polishing. The jig’s kinematic interfaces and precision-ground contact surfaces maintain true centration across the optical axis, preventing asymmetric figure errors and improving interferometric test results.

ISO 9001, AS9100 (for aerospace applications)

Technical Advantages

Optical Lens Polishing Jig maintains fixed tool-to-surface contact geometry under dynamic process loads. The structural rigidity of the fixture frame, verified via modal and harmonic analysis, reduces deflection to below 0.5 µm under operating forces, preserving mid- and high-spatial frequency integrity.

Optical Lens Polishing Jig supports quick tool changes through precision-located bayonet or dovetail assemblies. Positional repeatability of under 5 µm allows the same jig to be used across multiple platforms without re-qualification, improving uptime in multi-optic polishing workflows.

Infrared and Thermal Optics

Facilitates precise surface control of IR-grade materials like ZnSe, Ge, and chalcogenide glass for thermal imaging systems.

Astronomical Telescope Optics

Enables polishing of large aperture lenses with nanometer-level wavefront error requirements for deep-space and atmospheric observation systems.

Autonomous Vehicle LiDAR Lenses

Maintains optical axis alignment and uniform material removal in freeform lenses for scanning and ranging in mobility sensor modules.

Thermal and Chemical Stability

Material selection for the Optical Lens Polishing Jig prioritizes dimensional stability under process temperatures up to 90°C and resistance to acidic or basic slurry chemistries. Components are machined from passivated stainless steel, ceramic-filled polymers, or anodized aluminum with proven chemical compatibility and low CTE mismatch.

Optical Lens Polishing Jig is adaptable to CNC-controlled sub-aperture tools and manual pitch-based polishing platforms. Interface customization allows precise alignment with spindle centerlines, while maintaining compatibility with planetary drives, gimbal systems, and free-form optical paths.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate’s Optical Lens Polishing Jig minimize surface irregularity during CNC sub-aperture polishing?

Frigate’s jig maintains sub-micron axial concentricity through precision-lapped seating interfaces and rigid frame design. This reduces deviation during high-frequency tool paths in CNC polishing. Dynamic forces are absorbed without lateral displacement, ensuring controlled dwell time and uniform removal. The result is minimized mid-spatial frequency error and consistent optical flatness.

What material combinations does Frigate offer for Optical Lens Polishing Jigs used in corrosive slurry environments?

Fregatte uses a combination of passivated stainless steel, anodized aluminum, and high-performance polymers like PEEK. These materials resist degradation from cerium oxide, alumina, and colloidal silica slurries. Mechanical properties remain stable across long polishing durations and high-temperature cycles. This ensures repeatable jig performance without contamination or warping.

How does Frigate ensure repeatability in Optical Lens Polishing Jig setups across different machines?

Frigate’s jigs feature modular base plates and precision locating features with ±5 µm repeatability. These enable consistent repositioning across CNC polishers, manual pitch tools, or planetary polishers. The need for recalibration is eliminated, reducing non-productive setup time. Fixtures are designed for high-mix production with no compromise in alignment.

Can Frigate’s Optical Lens Polishing Jig accommodate high-aspect-ratio optics without introducing deflection?

Frigate designs each jig with FEA-optimized load distribution to support thin or elongated optics. Structural deformation under tool pressure is kept under 0.5 µm. Custom back supports and constraint zones prevent sagging or uneven material removal. This makes the jig suitable for optics with low rigidity or large diameter-to-thickness ratios.

How does Frigate address vibration isolation in Optical Lens Polishing Jig systems for nanometer-level surface finishes?

Frigate integrates elastomeric isolators or damping interfaces at the base of the jig assembly. These reduce vibrational energy transfer from machine tools into the optic. The design helps preserve surface roughness in the single-digit nanometer range. This is critical when polishing lenses for interferometric or laser-grade applications.
