surface aluminum. Solid line is reflectance for al + SiO2.
Broken line represents enhanced Al reflectance.
Enhanced Aluminum Mirror - The front surface mirror is considerably
more efficient than the standard aluminum overcoated mirror. The
increase in reflectance is approximately 6% without significant
loss of bandwidth. (upper curve)
Standard Aluminum Mirror -
The lower curve shows optical performance for our standard aluminum
mirror with quartz overcoat. Durability is excellent (conforms to
MIL-M-13508). The mirror can be washed repeatedly with detergent
and water or almost any non-abrasive glass cleaner.
Silver Mirror -
mirrors provide high reflectance above 0.4 microns. An overlayer
is provided for protection. It should be noted that ultraviolet
reflection is generally too low to be useful.
mirrors are useful in the infrared beyond 0.7 microns. Reflectance
is almost total with an average above 98%. An additional protective
overlayer can be provided with no significant loss in overall
