Multi-order construction enables a single thicker plate to replace a compound zero-order design, reducing cost while preserving high transmission and damage threshold. Each plate is anti-reflection V-coated on both surfaces (R \u0026lt; 0.25% @ design wavelength, 6° incidence angle) and is supplied as an unmounted optical element.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-order quartz design: mλ+λ\/2 retardance (m is a positive integer)\u003c\/li\u003e\n\u003cli\u003eDelay accuracy: ±λ\/100\u003c\/li\u003e\n\u003cli\u003eV-type anti-reflection coating: R \u0026lt; 0.25%ᵃ @ design wavelength, 6° AOI, per surface\u003c\/li\u003e\n\u003cli\u003eSurface finish: 20\/10, parallelism \u0026lt; 3 arcsec\u003c\/li\u003e\n\u003cli\u003eTransmitted Wavefront Error (TWE) @ 633 nm verified\u003c\/li\u003e\n\u003cli\u003eBare element for custom mounting or integration\u003c\/li\u003e\n\u003cli\u003eDesign wavelengths from 266 nm to 1550 nm (optional by request)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePolarization rotation and extinction control\u003c\/li\u003e\n\u003cli\u003eLaser isolator and interferometry systems\u003c\/li\u003e\n\u003cli\u003eEllipsometry and polarization-resolved imaging\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":47515491795098,"sku":"HWP20-808BM","price":420.74,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/2-1_E7_9F_B3_E8_8B_B1_E5_A4_9A_E7_BA_A7_E4_BA_8C_E5_88_86_E4_B9_8B_E4_B8_80_E6_B3_A2_E7_89_87_EF_BC_8C_E6_9C_AA_E5_AE_89_E8_A3_85-Fkh5gqJbIkKU-TNCsbdfrw9ntG_v_a7bb4a40-dcf5-4f7c-8ee0-7f265869dfa3.jpg?v=1772635095","url":"https:\/\/waveqvanta.com\/products\/quartz-multi-order-half-wave-plates-hwp20-808bm","provider":"WaveQuanta","version":"1.0","type":"link"}
