WE'VE DISCOVERED THE SECRET TO LONGER LIFE.

Thanks to Hamamatsu, your instruments can now live longer, healthier lives. The advantage comes from our new line of MOS Linear Image Sensors which provide superb immunity from UV degradation without sacrificing sensitivity. They also offer good linearity, low dark current and a choice of either serial/current, serial/voltage or random address readout. And our line of peripheral circuits makes it easy to incorporate them into your designs. Discover the secret to longer life. For complete information, call 908-231-0960.
