The 05D20ER.1-PF Pinhole Free Broadband Metallic Mirror was developed to be virtually free of pinholes. Tiny pinholes in a metallic coating can increase scatter from a mirror. It is ideal for sensitive applications requiring an economical broadband reflector. This 1/2 inch (12.7 mm) diameter mirror is made from a 3.1 mm thick Borofloat® 33 substrate. Borofloat has low thermal expansion and is an excellent substrate for most applications. The ER.1-PF enhanced aluminum coating may be used wherever a broadband visible and near infrared reflector is needed. A multilayer dielectric stack deposited over the aluminum film boosts reflectance and improves the durability of the coating. Average reflectivity is greater than 93% from 450–700 nm. This mirror has a λ/10 surface flatness and a 15-5 surface quality.

05 d20开头。1-PF无针孔宽频带金属反射镜已发展到几乎无针孔。金属涂层上的小针孔会增加镜面的散射。这是理想的敏感应用需要一个经济的宽带反射。这1/2英寸(12.7毫米)直径镜子是用3.1毫米厚Borofloat®33衬底。硼泥热膨胀率低,是大多数应用的优良基体。ER.1-PF增强铝涂层可用于需要宽带可见和近红外反射器的任何地方。沉积在铝膜上的多层介质堆叠可以提高反射率,提高涂层的耐久性。在450-700 nm范围内,平均反射率大于93%。这个镜子λ/今天比赛10表面平面度和表面质量。
