RCA Lancaster — where people and technology make the difference.
Now RCA expands its broad technical capability in phototubes for spectroscopic applications to give you the specific tube you need. For the highest perfor mance characteristics look to RCA's complete line of photo tubes including these new side-on types: • Type 1P28B . . . features guaranteed anode current stabili ty, and high photocathode and anode sensitivity (typically 60 A/lm and 250 A/I m @ 1000 V). • Type 4832 . . . features very high photocathode sensitivity (typically 400 μΑ/lm), and a virtu ally flat spectral response over most of its useful range, 185 to 950 nm. • Type 4837 . . . anti-hysteresis design with a fused-silica enve lope providing excellentUVsensitivity over a useful spectral range of 165 to more than 660 nm. • Type C31043A . . . in develop ment. First RCA multialkali photocathode in a competitivelypriced side-on structure. Objec tive spectral range: 185 to 900 nm • Type 931Β . . . similar to, but better performance than, type 931 A. Useful spectral range: 300to over 660 nm. Guaranteed anode current stability. • Type C31004 . .. photocathode similar to S-1; for near IR applications up to 1200 nm.
