Ophthalmic Laser Head Bracket

The Ophthalmic Laser Head Bracket is designed to maintain optical path stability during extended laser procedures by resisting dimensional changes caused by non-uniform thermal loading. Constructed from low CTE materials such as Invar or stabilized aluminum composites, the bracket minimizes micro-shifts from localized heating near laser diodes.

Product Description

This thermal stability is essential for preserving precise optical axis alignment, especially in systems using beam steering or galvanometer mirrors. Even sub-millimeter deviations can result in inaccurate laser targeting on the retinal surface, making the bracket’s performance critical to surgical accuracy and patient safety.

Hardness Requirement

60-70 HRB (Al), 85-95 HRB (SS), 32-36 HRC (Ti)

Straightness & Angularity

Straightness ≤0.01mm/100mm, Angularity ≤0.02°, Perpendicularity ≤0.015mm

Technical Advantages

Mechanical isolation performance of the Ophthalmic Laser Head Bracket directly impacts beam stability during ophthalmic procedures that involve patient movement or dynamic table-mounted configurations. The bracket integrates decoupled mount planes and elastomeric dampers that attenuate mechanical resonance across 10–200 Hz frequency bands typical of surgical environments. Structural eigenmode optimization via finite element analysis ensures the bracket does not amplify vibrational harmonics introduced by positioning arms or HVAC-induced table micro-vibrations.  

Ophthalmic Laser Head Bracket is designed for deterministic reattachment of the laser head after disassembly without requiring re-tuning of the beam path. This is achieved through the use of high-precision dowel-pin referencing, matched-machining on mounting faces, and tolerance-controlled bore concentricity to within ±5 µm. These features allow technicians to perform lens cleaning or fiber maintenance with guaranteed repositioning of the laser source in its exact mechanical envelope.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure positional accuracy in the Ophthalmic Laser Head Bracket during dynamic laser alignment?

Frigate uses precision 5-axis machining to control all datum faces and bores in a single clamping sequence. This eliminates cumulative tolerance errors and improves centerline alignment of the laser path. Finite Element Analysis (FEA) is conducted on the bracket’s flex zones to minimize dynamic deflection under optic module weight. This ensures micron-level targeting precision during ophthalmic surgeries. 

What material considerations does Frigate incorporate for thermal stability of the Ophthalmic Laser Head Bracket?

Frigate selects aerospace-grade aluminum alloys with low coefficient of thermal expansion (CTE) and high dimensional stability. All brackets undergo artificial aging and stress relieving to neutralize residual machining stresses. This controls bracket deformation under sustained thermal loads from the laser module. It ensures consistent beam path alignment across varying clinical duty cycles. 

 

How does Frigate achieve vibration damping in the Ophthalmic Laser Head Bracket for high-precision optical performance?

Frigate incorporates internal rib geometries and mass-tuned cavities to suppress harmonic amplification during laser head actuation. Bracket structures are evaluated using modal analysis to identify and shift resonant frequencies away from surgical bandwidths. Critical contact points are selectively filled with vibration-absorbing polymer-metal composites. This preserves optical coherence and reduces image jitter in real-time procedures. 

How are interface tolerances managed by Frigate on the Ophthalmic Laser Head Bracket for modular system integration?

All mounting interfaces are controlled to within ±5 microns using high-speed coordinate measuring machines (CMM) post-machining. Frigate applies geometrical dimensioning and tolerancing (GD&T) to control parallelism and perpendicularity across orthogonal planes. This supports drop-in interchangeability across modular laser head variants. Consistency in mechanical interface geometry ensures no recalibration during field replacements. 

 

What is Frigate’s approach to managing EMI shielding in the Ophthalmic Laser Head Bracket for sensitive electronics?

Frigate applies selective electroless nickel plating to internal cavities where control electronics reside. This provides uniform conductivity and continuity across the bracket surface without masking critical optical interfaces. Additional grounding bosses are integrated into the bracket design for direct PCB chassis connections. These methods suppress electromagnetic noise and protect precision diagnostics from external interference.
