Economy Square Broadband Metallic Mirrors
Economy Square Broadband Metallic Mirrors
Economy Square Mirrors set a new standard of value and performance. They are best suited for prototype development, proof-of-concept or educational applications, where power loss, dispersion or wavefront distortion are not critical.
- Best value square mirrors for general purpose lab use
- 40-20 scratch-dig Borofloat® 33 substrates
- Broader bandwidth and less expensive than dielectric coatings
- Four metallic coatings covering the UV to IR bands See All Features

Features
Borofloat® 33 Substrates
Borofloat 33 is a high quality borosilicate glass that offers low thermal expansion and high thermal shock resistance. Its material properties and moderate cost make Borofloat 33 an ideal substrate for general purpose applications. For more information, please see our Optical Materials technical note.
Maximum Value Optics
Newport's economy class of optics includes mirrors, lenses, objectives, and prisms. They were developed for customers who require inexpensive yet effective optics to perform prototyping, basic optical demonstrations or experiments. The performance of our economy class of optics is equivalent to many other commercially available products at similar prices. They provide maximum value while delivering the quality associated with Newport products. For more information, refer to Economy Optics Selection Guide.
Enhanced Aluminum UV Coating
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.
Enhanced Aluminum VIS-NIR Coating
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.
Protected Silver VIS-IR Coating
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.
Protected Gold NIR-IR Coating
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.
