Component Specifications

Definition
A mechanical mounting component designed to securely hold and position optical filters within optical assemblies. It provides precise alignment, vibration resistance, and thermal stability while maintaining optical path integrity. The mounting ring/frame ensures the filter remains perpendicular to the optical axis and prevents displacement during operation.
Working Principle
The mounting ring/frame operates on mechanical retention principles, using clamping force, threaded engagement, or snap-fit mechanisms to secure optical filters. It maintains precise positioning through dimensional tolerances and alignment features, while allowing for thermal expansion compensation and minimizing stress-induced birefringence in the optical element.
Materials
Aluminum alloy (6061-T6, 7075-T6), stainless steel (304, 316), titanium alloy (Grade 5), or engineered polymers (PEEK, Ultem) with appropriate surface treatments (anodizing, passivation, black oxide coating).
Technical Parameters
  • Parallelism <0.005 mm
  • Surface Finish Ra 0.8 μm or better
  • Diameter Tolerance ±0.01 mm
  • Thread Specification M25x0.5 or custom
  • Operating Temperature -40°C to +120°C
  • Thermal Expansion Coefficient Matched to filter substrate
Standards
ISO 10110, ISO 14999, DIN 3140, DIN 58750

Frequently Asked Questions

What are the key considerations when selecting a mounting ring for optical filters?

Key considerations include: material compatibility with the filter substrate to prevent differential thermal expansion, dimensional tolerances for precise alignment, surface finish to minimize scattering, mechanical stability under vibration, and compliance with optical standards for wavefront distortion.

How does the mounting ring affect optical performance?

Proper mounting prevents filter tilt (maintaining perpendicularity to optical axis), minimizes stress-induced birefringence, reduces vibration-induced misalignment, and maintains thermal stability. Poor mounting can cause beam deviation, polarization effects, and reduced transmission efficiency.

Can mounting rings be customized for specific optical systems?

Yes, mounting rings are frequently customized for diameter, thickness, mounting interface (threaded, flange, snap-in), material selection, and special features like thermal compensation slots or alignment pins to match specific optical system requirements.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
