Prevention of beam clipping is important in beam steering applications with larger beam diameters. Circular mirrors mounted at 45° cannot maintain a circular profile and may result in portions of the beam not being reflected. The solution is to mount elliptical mirrors at a 45° angle – presenting a circular profile to an incoming beam – with Newport's Large Diameter Periscope Mounts and 1.5 inch Gear Rack Support Rods.
Our AL.2 UV enhanced aluminum coating is a durable, broadband UV reflector with average reflectivity greater than 90% from 250 – 600 nm. The aluminum film is overcoated with UV transparent magnesium fluoride to prevent oxidation of the metal.
Our ER.1 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.
Our ER.2 protected silver coating is composed of a low emissivity silver film fully encapsulated by a multilayer dielectric stack to prevent oxidation. This coating has excellent broadband reflectivity in the IR, while maintaining very good performance in the visible and near IR. Average reflectivity is greater than 96% from 480 – 1100 nm and greater than 98.5% from 1.1 – 20 µm. This silver mirror is a favorite for Ultrafast scientists who want an inexpensive option.
Our ER.4 protected gold coating is ideal for applications requiring broadband reflectance in the near IR to the far IR. A multilayer dielectric overcoat provides protection to the gold from the environment. Average reflectivity is greater than 96% from 650 – 1700 nm and greater than 98% from 1.7 – 2.0 µm.
Elliptical Broadband Metallic Mirrors are available with N-BK 7 or Borofloat® 33 substrates. BK 7 is a borosilicate crown glass used for visible and near infrared optics. It offers high homogeneity, low bubble and inclusion content and is relatively hard with good scratch resistance. Borofloat is borosilicate glass with a low coefficient of thermal expansion. It is mainly used for non-transmissive optics, such as mirrors, due to its low homogeneity and high bubble content. Please see the Optical Materials Technical Note for more details.
