2.  Select the DC volts mode. 
 
3.  Direct the laser beam on to the absorbing surface of the calorimeter. 
 
4.  When the display of the DVM has stabilized (about 2 minutes), calculate the laser power using the 

formula:    W = V/S   

 
where:  
W = Laser power in watts 
V = Voltage reading of the DVM in volts 
S = Sensitivity of the calorimeter which is 0.5 V/W for 25 mm and 0.167 V/W for the 50 mm calorimeters. 
 
 
 

Operation of Astral Calorimeters with an Analog Chart Recorder 

 
Calorimeter Response 
The response of a calorimeter to a single pulse input as displayed by a chart recorder appears below. 
 
 

 

 

 

 

 

The output voltage from a chart recorder can be converted to wattage at any time by: 
 
     W = V/S, W

i 

= V

i

/S 

 
     V =  Chart recorder voltage level in mV 
     S =  Calorimeter sensitivity in mV/W 
 
The total energy (E) in the pulse can be found by integrating the instantaneous wattage over time: 
 

∞

 

     E = 

∫

 W(t) dt 

 

0

 

 
The following methods may be used to compute the total integrated energy:
