HAMAMATSU R6350, R6351, R6352, R6353, R6354 Datasheet

New Electro-Optical Design

13mm (1/2 Inch) Diameter, 9-stage, Side-on Type

Our new electro-optic construction allows Hamamatsu to introduce
an improved line of compact side-on PMTs. The X-axis anode uni­formity full width half maximum (FWHM) is greater than existing
models. This wider "sweet" spot increases detection efficiency and
can make optical alignment easier.
The R6357 is a unique addition, it is the new meshless multialkali
compact PMT having over 100mA/W photocathode radiant sensitiv­ity.

NEW COMPACT TYPE

APPLICATIONS

Emission Spectroscopy (ICP, Direct Reader)
Environmental Monitoring (NOx, SO2, etc.)
Fluorescence Immunoassay
Chemiluminescence Immunoassay
Hygiene Monitor (Bio Luminescence)
X-ray Phototimer
Fluorometer
Microscope (Laser Scanning Microscope)

* Achieved the higher photocathode sensitivity by eliminating the mesh in front of the photocathode.
It also features no output variation, disturbed by the mesh, when the incident light spot to the photocathode is small.
