斜方棱镜，菱形棱镜

斜方棱镜
斜方棱镜或菱形棱镜，常用于偏移入射光束而不产生角度偏差或方向变化。在成像应用中，它们将使光学中心线偏移棱镜长度“L”，而不会反转图像。
福州光骅达可提供镀膜和不镀膜两种斜方棱镜（菱形棱镜）。
产品特点：
•光束横向位移
•在不反转图像的情况下移动光轴
•输入和输出光束平行度在±30弧秒
•也可使用我司的光束位移道威棱镜
作为专业的斜方（菱形）棱镜供应商，福州光骅达Photonchina长久以来一直致力于为国内外客户提供质量可靠产品。我们保证所有产品都经过严格的质量控制，从而在客户的实际使用中表现优异。
Rhomboid prisms are used to shift an incident beam without angular deviation or orientation change. In imaging applications, they will displace the optical centerline by the prism length “L” without inverting the image.
These prisms are available both uncoated and coated.
Features:
•	Lateral displacement of beam
•	Displaces optical axis without Inverting Image
•	Input and output beams parallel to ±30 arcseconds
•	Beam displacing Dove Prisms also available
As top-ranked supplier of rhomboid prisms, Photonchina has been satisfying customers worldwide by offering design and manufacturing service for more than decades. From first cut to final stage of production, we ensure that all products have been under strict quality control and thus conduct excellent performance in customer’s real use.
