R^PH9^OT2^O8^M,^UR^LTI9^PL5^IE5^{R TUBES}

Extended Red, High Sensitivity, Multialkali Photocathode

28 mm (1-1/8 Inch) Diameter, 9-Stage, Side-On Type

The R928 and R955 feature extremely high quantum effi-

ciency, high current amplification, good S/N ratio and

wide spectral response from UV to near infrared. The

R928 employs a UV glass envelope and the R955 has a

fused silica envelope for UV sensitivity extension.

The R928 and R955 are well suited for use in broad-band

spectrophotometers, atomic absorption spectrophotomet-

ers, emission spectrophotometers and other precision

photometric instruments.
