      Solar Blind UV Photomultiplier (PMT) Sensor

 
Ofil's unique DDP filter technology has enabled the development of filter/PMT
sensor combinations that are completely non-responsive to sunlight while
maintaining high UV sensitivity. The exclusive use of absorbing components in
the filter guarantees that the spectral characteristics are independent of the angle
of incident light.
