Astral Calorimeters
The premier Astral Series is the "star" in a long line of
calorimeters bearing the name of Scientech. Since 1968, Scientech has been
the standard in laser measurement for accuracy and quality. Now new heights
have been reached in features as well as performance in the exclusive Astral
Series. These dynamic calorimeters bring accuracy and precision into your
measuring environment while empowering you with superb features.
Astral calorimeters are available in both surface absorbing and volume
absorbing models with either 10 watt or 30 watt capabilities. The broadband
surface absorbing models are ideal for measuring CW lasers. With the addition
of the new high damage threshold "HD" and "ACX" models,
power densities up to 12 kW/cm2, peak pulse power densities up to 100 GW/cm2
and energy densities up to 15 J/cm2 are handled by various models.
Features:
- Intelligent sensor technology
- The calorimeter automatically identifies itself to the indicator.
- Different calorimeter models are easily interchanged with the indicator.
- Low signal to noise ratio enhances accuracy.
- Improved EMI/RFI protection is ensured.
- Slim 5.6 cm long silhouette
- Ability to resolve to 10 µW and 10µJ
- N.I.S.T. traceable calibration
- Optional calibration heaters
The Astral calorimeters come with a 1.27 cm (0.5") diameter x 8.89
cm (3.5") long post for mounting to an optical table. Bases (Model
301-019) for holding the calorimeter/mounting post assembly upright are
also available. The slim profile silhouette of the calorimeters saves precious
optical table space. For measuring low power and energy (less than 30 mW
or 30 mJ), Scientech recommends the optional Isoperibol Enclosure accessory
(Model 36-0203A) which minimizes environmental thermal interference.
Astral calorimeters can be fitted with optional electric substitution
calibration heaters. Absolute self-calibration can then be easily
accomplished at your own facility using a dc power supply and digital volt
meter.
The Astral calorimeters are powered up by the Vector Synenergy Indicators
to provide precise watt or joule readings. Choose between the digital/analog
indicator Models S310 or H410, the digital only models S310D or H410D,
or one of the dual channel Models D200C or D200PC.
