Depolarizeroptics

By utilizing a new rotating barrel design, the Fresnel 2X creates an intuitive user experience, similar to a camera lens. The smooth focus throw gives users an ability to accurately finesse the beam angle of their light source, allowing you to easily spot or flood your light with a simple twist.

The Fresnel 2x design features dual optical intensifying elements, a large 5.5” front Fresnel lens, improved ventilation, and the elimination of light leaks, making this the ultimate Bowens Mount Fresnel.

By utilizing a universal Bowens Mount, this fresnel can be attached to a myriad of lights. The 7” front ring also accepts the Aputure Barndoors, meaning your light shaping options are endless. With the included carrying case, the Fresnel 2X can easily follow you wherever your shoots may take you.

The PFDP Passive Optical Fiber Depolarizer is an all-fiber device that converts polarized input into random polarization output, featuring ultra-fast response, low cost, high power handling, and no electrical power requirements. It employs multiple fiber couplers arranged in series to achieve polarization scrambling, where each coupler introduces changes in polarization due to slight birefringence variations and random phase shifts. The cumulative effect results in complex, non-deterministic polarization changes, effectively scrambling the input light. This versatile method allows optimization of coupling ratio, birefringence, and fiber alignment to depolarize specific types of lasers, making it effective for reducing polarization-dependent loss (PDL) and polarization mode dispersion (PMD) in optical communication systems, preventing artifacts in Optical Coherence Tomography (OCT), and ensuring consistent measurements in fiber sensing systems. The device accepts single-mode (SM) or polarization-maintaining (PM) fiber inputs with a single-mode output. However, it is not suitable for narrow-line lasers like Fiber Bragg Grating (FBG) and Distributed Feedback (DFB) lasers, and its design is best suited for large quantity orders, requiring customization to optimize performance for specific laser sources.

The rear lens focuses and magnifies the beam onto the larger 5.5” front Fresnel lens, maximizing light utilization. Our dual lens optical design makes the Fresnel 2X twice as powerful as the original Aputure Fresnel, and makes the 120d II almost 10 times brighter than with the reflector.
