Multi-pass Cavity Assembling
with Anodic Bonding.
The mirror cavity is assembled by precisely positioning and bonding two optical mirrors onto a common substrate to form the required multipass optical path. Anocly bonding can be used to permanently join the mirror components while maintaining their designed angular and positional relationship. Before bonding, the mirrors are aligned to achieve the required beam trajectory, cavity spacing, and number of passes through the optical region.
Multi-pass Cavity Assembling with Optical Contact Bonding.
Alternative to anodic bonding, the same cavity configuration can be assembled using optical contact bonding, where ultra-clean, optically flat surfaces are brought into intimate contact to form a strong bond without an intermediate layer. This approach does not require heating process and optical distortion free. Both bonding methods enable a compact and mechanically stable multi-pass cavity with precise optical alignment and long-term dimensional stability.
Assembling The Fabry–Perot Cavity.
The Fabry–Perot cavity can be assembled using optical contact bonding or Hydroxide Catalysis Bonding (HCB) to create a compact and stable optical structure. Mirrors and, where required, lenses are precisely positioned and aligned to define the cavity length, optical axis, and beam propagation path. Optical contact bonding and HCB provide a clean, adhesive-free interface between optical surfaces. These bonding techniques eliminate bulky mechanical mounts, minimize differential thermal expansion, and reduce thermally induced stress and alignment drift within the Fabry–Perot cavity. The mirrors and lenses can be actively aligned before bonding to optimize cavity transmission, mode matching, and overall optical performance.
Multi-pass Cavity Assembling for Liquid Cell.
A liquid flow cell can be assembled with AR-coated optical windows to minimize optical losses and enable efficient coupling into a multi-pass cavity. The windows can be optically contact bonded to provide a clean, stable seal suitable for liquid flow pressures up to 50 psi, subject to pressure and leak testing. Integrated with a Herriott-type mirror configuration, the cell provides multiple passes through the liquid, increasing the effective optical path length and enhancing spectroscopic detection sensitivity.
