The 50394-2530 is a Replicated Hollow Metal Retroreflector with an outside diameter of 63.5 mm and a 30 arc sec Return Beam Accuracy.
Our replicated hollow metal retroreflectors are monolithic or single piece construction. Fabricated from a solid piece of Aluminum, the facets of the mirror cannot shift and return beam accuracy is unaffected by vibration. Using front-surface reflection, the mirrors are achromatic and require no wavelength-dependent refraction offset. We offer 4 standard sizes of high-precision cylindrical retroreflectors, each with 3 different high-precision return beam accuracies. We also offer a 2.5 in. hexagonal shaped, retroreflector with 30 arc sec. return beam accuracy for applications that do not require the precision of our 50326 series retroreflectors. The mirrors are coated with bare Gold, which provides very high reflectance from the near infrared through long wave infrared.

50394-2530是一种复制的空心金属反光镜，外径63.5 mm，反射光束精度30弧秒。我们复制的空心金属反光镜是单片或整体结构。该反射镜由一块实心铝制成，反射面不能移动，反射光束的精度不受振动影响。使用前表面反射，镜子是无色的，不需要波长依赖的折射偏移。我们提供4个标准尺寸的高精度圆柱反光镜，每个具有3个不同的高精度回射光束精度。我们也提供2.5英寸的。六角形的反射镜，具有30弧秒的反射光束精度，适用于不需要50326系列反射镜精度的应用场合。镜子表面镀有裸金，从近红外到长波红外具有很高的反射率。
