These general purpose, D-shaped mirrors are highly efficient over a broad wavelength range and ideal for beam pick-off applicatioins
- Pick-off tightly spaced beams
- Four metallic coatings covering the UV to IR bands
- Fused Silica substates
- Broader bandwidth and less expensive than dielectric coatings
The Ideal Choice for Beam Pickoff Applications
D-shaped pickoff mirrors are specifically designed to enable the separation of closely spaced optical beams. The reflective coating extends to near the flat edge of the mirror allowing for the pickoff of one of the two beams.
Fused Silica Substrates
Fused Silica is a high quality mirror substrate offering excellent λ/10 surface flatness and 15-5 scratch-dig surface quality.
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.
