SuperK VARIA
The VARIA accessory acts as a bandpass filter when connected to the collimator
of the SuperK COMPACT laser. A portion of the beam from the SuperK
COMPACT is diverted to the VARIA’s bandpass filter which removes the light
wavelengths that fall outside a variable wavelength range. The filtered beam is
then emitted from the main optical output. The CONTROL PC connected to the
SuperK COMPACT controls the VARIA through the laser’s front panel external
bus connector connected to the VARIA’s bus input connector. CONTROL
configures the range of the VARIA’s bandpass filter and the beam portion not
diverted to the bandpass filter can be output from the auxiliary optical output. A
diagram of the main accessory connections is shown in Figure 65.
