Fiber Optic Michelson Interferometer - OCT
The FMIM Series Fiber Optical Michelson Interferometer utilizes a fiber optic coupler to split incoming light into two optical paths, which are then recombined to generate an interference pattern for precise measurement applications. Engineered for a flat wavelength response and exceptionally low polarization-dependent coupling ratio change (PDCR), the FMIM delivers output signals that are virtually unaffected by input polarization variations. Optimized for both swept-source Fourier domain and time-domain OCT systems, it features dual optical outputs functioning as the reference and sample arms, with interference fringes captured by an integrated balanced detector. An optional aiming laser input is available to simplify sample alignment.

Mach-Zehnder Interferometer K-Clock Box
The KCLK Series k-Clock Box is a timing device for swept-source Optical Coherence Tomography, designed to linearize the sampling of interferometric signals in k-space (𝑘=2𝜋/𝜆) rather than time or wavelength. It uses a Mach-Zehnder interferometer (MZI) with a fixed optical path difference (OPD) to generate zero crossings at uniform k-intervals, which are converted into digital pulses that trigger the analog-to-digital converter (ADC) for precise, k-linear data acquisition. The unit includes a fiber coupler network that provides both the k-clock and a power monitor signal to track laser output power and wavelength, with low polarization sensitivity. The spacing between k-clock pulses is determined by the MZI’s OPD, with larger OPD yielding higher clock frequencies and denser sampling.
