{"product_id":"fiber-polarization-controllers-ft-t15-n-1","title":"Fiber Polarization Controllers FT-T15-N","description":"\u003cp\u003eLBTEK's mechanical three-loop polarization control is based on the principle of birefringence induced in optical fibers under external force. The three loops function equivalently as λ\/4, λ\/2, and λ\/4 waveplates respectively. By adjusting the rotation angles of these three loops in coordination, the polarization state of incident light can be transformed into any desired polarization state.  \n\nThe retardation effect caused by birefringence is primarily determined by the fiber cladding radius, fiber loop radius, and the wavelength of the input light. The number of fiber loops required for different wavelengths can be calculated using the formula provided in the technical specifications.  \n\nLBTEK offers two options for polarization controllers: empty polarization controllers and pre-installed fiber polarization controllers. The polarization controllers are mainly designed for use with fibers protected by Ø900 µm sleeves.\u003c\/p\u003e\n\u003cul class=\"lbtek-features\"\u003e\n\u003cli\u003eThree-Rring Type\u003c\/li\u003e\n\u003cli\u003eProvides Various Ring Diameter Specifications\u003c\/li\u003e\n\u003cli\u003eOffers Empty Polarization Controllers and Pre-Installed Fiber Optic Controllers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"lbtek-explain\"\u003e\u003cimg src=\"https:\/\/images.lbtek.com\/uploads\/images\/others\/20240325\/a2e7578082b9fa6106a44afbf8c0daac.jpg\" alt=\"Specifications diagram\" loading=\"lazy\"\u003e\u003c\/div\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47499462639770,"sku":"FT-T15-N","price":254.39,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E4_B8_89_E7_8E_AF_E5_BC_8F_E5_81_8F_E6_8C_AF_E6_8E_A7_E5_88_B6_E5_99_A8-Fhao_dXoPy8-GjB1zQqmu_7Z7Sjw_50963e62-2350-4c9a-84fd-b95823fd5741.jpg?v=1772281428","url":"https:\/\/waveqvanta.com\/products\/fiber-polarization-controllers-ft-t15-n-1","provider":"WaveQuanta","version":"1.0","type":"link"}
