The true zero-order single-plate quartz construction provides superior thermal and spectral stability with minimal beam deviation. Each plate is anti-reflection coated on both surfaces (R \u0026lt; 0.25% @ design wavelength) and mounted in a standard SM05 or SM1 lens tube for seamless integration into polarization control setups.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTrue Zero-Order design at the specified design wavelength\u003c\/li\u003e\n\u003cli\u003eRetardance: λ\/4\u003c\/li\u003e\n\u003cli\u003eV-type anti-reflection coating on both surfaces\u003c\/li\u003e\n\u003cli\u003eSurface finish 10\/5 to 20\/10\u003c\/li\u003e\n\u003cli\u003eOperating temperature tolerant, polarization-stable\u003c\/li\u003e\n\u003cli\u003eMounted in standard SM05 \/ SM1 housing for seamless integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePolarization state conversion (linear ↔ circular \/ elliptical)\u003c\/li\u003e\n\u003cli\u003eLaser isolator, interferometry, and ellipsometry systems\u003c\/li\u003e\n\u003cli\u003eQuantum optics and photonic research\u003c\/li\u003e\n\u003cli\u003eIntegration with polarizing beamsplitters and prisms\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47499860934810,"sku":"QWP20-780BT","price":1005.2,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E7_9F_B3_E8_8B_B1_E7_9C_9F_E9_9B_B6_E7_BA_A7_E5_9B_9B_E5_88_86_E4_B9_8B_E4_B8_80_E6_B3_A2_E7_89_87-Ft1p0iA_QuTQxjd07Yz4AdXj0R0b.jpg?v=1772283704","url":"https:\/\/waveqvanta.com\/products\/quartz-true-zero-order-quarter-wave-plates-qwp20-780bt","provider":"WaveQuanta","version":"1.0","type":"link"}
