Properties
and Application
|
|
Low-order Waveplate
|

|
Its properties are much better than the multi-order
waveplate because of its thinner thickness (less
than 0.5mm). Better temperature (380C),
wavelength (1.5nm) and incident angle (4.50)
bandwidth and high damage threshold make it widely
used in common application. Also, it is economical.
|
|
Zero-order waveplate
|
Cemented And
Optically Contracted
|

|
It is constructed of two multi-order waveplates with
their axis crossed. Thus, it performs as a zero-order
waveplate because of the effect of two plates counteracting
each other. It has wide temperature bandwidth and
wavelength bandwidth properties. Because it is cemented,
the damage threshold must be considered (about 10MW/cm2)
when used.
|
|
Air-spaced
|

|
Its performance is as good as cemented zero-order waveplate.
Additionally, the air-spaced construction enables
it is suitable for the high power laser application.
The damage threshold is more than 500MW/cm2.
|
|
True Zero-order Waveplate
|
Cemented
|

|
The true zero-order waveplate means that the thickness
of waveplate is very thin (less than 0.1mm) which
make the true zero-order waveplate excellent in
temperature, wavelength and incident angle (about
20º) bandwidth. Therefore, it is excellent
choice for the highly accurate application. It is
cemented with a block of glass which is limited
to low and medium power application.
|
|
Single Plate
|

|
In order to enable the waveplate suitible for high
damage threshold (more than 1GW/cm2)
application: Tempotec provides a single plate of
true zero-order waveplate
*The thickness of this waveplate means handling can
be difficult, we can provide mounts upon request.
