The JW1512 Mechanical Adjustable Polarizer is a testing device with excellent performance, specially designed by Shanghai Jiahui for polarization-related testing. Its high-density design greatly saves the equipment's footprint; the all-glass polarizer can arbitrarily convert input light into linearly polarized light, with 360-degree continuous adjustment; it features a high extinction ratio and low insertion loss. It can meet different polarization state measurement needs, and is very suitable for monitoring changes in polarization state over time, testing polarization extinction ratio (PER), and building variable beam splitters.
