Fresnel Rhomb Retarders

Fresnel Rhomb Retarders amakonda ma waveplate a burodibandi omwe amapereka yunifolomu λ/4 kapena λ/2 kuchedwetsa pamitundu yotalikirapo ya mafunde kuposa momwe angathere ndi ma waveplates a birefringent.Atha kulowetsa mbale zopumira pamabwalo amtundu wa Broadband, mizere yambiri kapena makina osinthika a laser.

Rhomb idapangidwa kuti kusintha kwa gawo la 45 ° kumachitika pachiwonetsero chilichonse chamkati ndikupanga kuchedwa kwathunthu kwa λ/4.Chifukwa kusintha kwa gawo ndi ntchito ya kufalikira kwapang'onopang'ono kwa rhomb, kusintha kwa retardance ndi kutalika kwa mafunde kumakhala kochepa kwambiri kuposa mitundu ina ya retarders.The half wave retarder imaphatikiza ma quarter wave rhombs.

• Quarter-Wave kapena Half-Wave Retardance

•Kutalikirana kwa Wavelength kuposa ma Waveplates

•Ma Prisms
