楔形棱鏡

光驊達(dá)光電的楔形棱鏡以及圓形楔形棱鏡是激光束控制應(yīng)用的理想選擇。這種棱鏡也被稱為Risley棱鏡，這些光學(xué)器件通過2°到10°的角偏差使垂直于棱鏡垂直表面的光束偏轉(zhuǎn)。它們可以單獨(dú)使用，也可以與另一個楔形棱鏡組合使用，用于光束控制，鍍膜或者不鍍膜。在這種情況下，相對于另一個楔角棱鏡旋轉(zhuǎn)一個楔角棱鏡將改變光束的方向。當(dāng)棱鏡的角度相同時，折射光束的角度會變大。當(dāng)楔形棱鏡以相反的方向旋轉(zhuǎn)成一定角度時，它們相互抵消，光束可以直接通過。

玻璃材料N-BK7（Schott）/H-K9L（CDGM）、N-SF11通常用于制作楔形棱鏡。然而，其他材料也可用于某些指定的應(yīng)用。憑著豐富的經(jīng)驗(yàn)，福州光驊達(dá)光電作為專業(yè)的供應(yīng)商，多年來一直提供質(zhì)量可靠，價格優(yōu)勢的楔形棱鏡產(chǎn)品來滿足國內(nèi)外客戶的需求。

Wedge  Prism

 Photonchina’s wedge prisms,as well as round wedge prisms, areideal for laser beam steering applications. Also known as Risleyprisms, these optics deflect a beam normal to the prism'sperpendicular surface through an angular deviation ranging from 2°to 10°. They can be used individually or in combination withanother wedge prism for beam steering, with uncoated or coated. Inthis case, rotating one wedge in relation to the other will changethe direction of the beam. The angle of the refracted beam becomesgreater when the wedges angle in the same direction. When thewedges are rotated to angle in opposite directions, they canceleach other out, and the beam is allowed to pass straightthrough.
