Metallized Mirrors
Metallized Mirrors, Square
& Rectangular
- Rectangular shapes are useful for 45°
applications
- Highly reflective aluminum is over-coated
with MgF2
- Square shapes lend themselves to OEM
mounting
- Available with
/4, /10 and /20 surface flatness - Lower tolerance substrates are BK7 Optical
Glass, Grade A
- /20 substrates are synthetic
quartz for high thermal stability
|
|
While the round mirrors
fit perfectly in the Mirror Mounts, these square and rectangular mirrors are often
very convenient to mount in prototype and experimental setups. The
rectangular shapes are most useful in beam steering applications at
45-degrees. |
These square and
rectangular metallized mirrors are identical to the Round metallized mirrors.
The rectangular shapes are useful at 45 degrees since they present a more
nearly square cross section to the beam.
The reflectance curve for
these mirrors may be found on this graph. As with the round metallized mirrors there
are three levels of flatness available: /4, /10 and /20. The /20 mirrors have a synthetic quartz substrate
for thermal stability.
A selection of sizes are
offered as standard. Other sizes can be supplied on request. Please call.
Mirrors up to 1 inch square have a ground rear surface but all other mirrors
are polished on the rear face.
