For metallic and PD10 heads, the absorption of the detector coating varies 
somewhat according to wavelength. The correction curve for the absorber is 
stored in the head EEROM. This correction curve ensures that the power reading 
is correct at all laser wavelengths.  

To configure laser wavelengths, refer to Configuring Laser Wavelengths in 
Chapter 5 – Measuring with the Photodiode Head. 

Broadband (BB) heads have less variation according to wavelength. For 
broadband heads, fixed wavelength ranges are provided, similar to thermopile 
heads.  

To configure laser wavelengths, refer to Selecting the Laser Wavelength in 
Chapter 4 – Measuring with the Thermopile Head. 

Pyroelectric heads cover a wide range of energies (from tens of nanojoules to 
tens of joules) depending on the type of head in use. In order to provide accuracy 
throughout the range, the electronics of the head must be configured to work in a 
range that is most suited to your needs. 

1.  Select the range from the Range drop down list in the Measurement 

Parameters Area. The instrument will configure itself according to the 
selected range.
