A: at crystal photocathode
B: Depends on the input pulse width. Refe to Figuer 6 on page 6.
C: Relative value with output from P43 set as 1. Measured with 6 kV voltage applied.
D: Shutter time: Defined as the rise time. The input gate pulse width should be at least twice the shutter time.

image information to a readout device coupled by using a reduction optical system such as
a relay lens and tapered FOP. This lets you acquire high resolution images.
The 18 mm diameter type (13.5 mm × 10 mm) is compatible with 1-inch CCDs.
Wavelength [nm]
Standard output window and ideal for
highly efficient readout. If the phosphor screen is not at ground potential, a NESA (transparent
conductive film) may be needed to prevent noise generated by a high voltage from getting into
the CCD. When a relay lens is used, it should be focused on the edge of the FOP.
For relay lens
The output image is
a CCD camera with FOP window directly.
FOP twisted 180 ° to invert an image. This output window is only for nighttime viewing
applications where the output image is directly viewed by eye. Using a twisted fiber optics
reduces the eyepiece length, making the nighttime viewing unit more compact.
