Metallic Mirror
Metallic Mirrors descript a
good mixture of performance and value. These broadband coatings are
relatively insensitive to wavelength, angle of incidence, and
polarization. However high-energy levels should be avoided. Such metallic HR mirror are widely use in projection optics systems, imaging optics systems, Optical Measurement System, sensors or laser measurement systems.
Protected Aluminum For general broadband use, a protected
aluminum coating offers the best option. A SiO2 coating is used to
protect the delicate aluminum coating, making it suitable for
laboratory and industrial use. This coating gives a reflectivity
that most closely matches the reflection of a bare aluminum coating:

requirements. The general tolerance specifications above provide a
guideline regarding manufacturing capabilities for optics ranging in
size from 2-300mm. The manufacturing limits are not absolute;
tighter tolerances may be possible. Part specific tolerances may
vary depending on component size, shape, and/or
material. |
