Dielectric HR Mirror
Dielectric HR Mirror offers
near total reflection, minimizing losses in nearly all optical
systems. It has a high reflcetivity in a narrow band or broadband
wavelength. Such dielectric HR mirror are widely use in projection
optics systems, imaging, sensors or laser measurement
systems.
Available either broadband or narrowband, they
operate efficiently over 0¨C45¡ã angle of incidence: AOI=0¡ã,
R>99.8%; AOI=45¡ã, R>99.5% (Rs>99.9%,
Rp>99.2%). |

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. |
