ScienTECH Vector Series - Using the H410 with Vector Series Calorimeter

PN 10795T 19
Operating Parameters section at the front of the manual and on the detector’s serial tag. When a
pyroelectric detector is used at a wavelength other than the calibration wavelength, its output sensitivity
can be adjusted to compensate for the absorption rate at the new wavelength. The new output sensitivity
is calculated as follows:
1. Find the absorption rate from the chart at the end of this manual for the calibration wavelength of
your pyroelectric detector.
2. Find the absorption rate for the wavelength where you will be working.
3. Determine the new output sensitivity using the following formula:
absorption rate of new wavelength x output sensitivity (V/J) = output sensitivity for new
absorption rate of calibration wavelength wavelength from serial tag
This new output sensitivity can be entered into the H410 as described in Group Settings or when using the
pyroelectric detector without a H410 power meter as discussed later in this manual.
Using the H410 with Vector Series Calorimeter
The calorimeter selected needs to be the appropriate model for the planned laser measurements. Please
familiarize yourself with the operating specifications which are provided in the Vector™ Calorimeter
Operating Manual.
Note: Vector™ calorimeters are sensitive to all types of thermal input. Due to the handling of the
calorimeter during setup and possible environmental temperature differences, thermal gradients may exist
in the calorimeter. Allow the calorimeter to sit undisturbed for several minutes to, reach thermal
equilibrium, before using.
Note: When using a 25mm Vector™ calorimeter for measuring average power levels below 30mW and
single pulse energy levels below 30mJ, a Scientech Model 360203A, Isoperibol Enclosure, is highly
recommended. The isoperibol enclosure should not be used at average power levels above 30mW, and
single pulse energy levels above 100mJ because heat build-up will occur.
Note: Large Aperture calorimeters and the Interface Modules that they are calibrated with are matched
sets and must be used together.
