Description

The S2592-04 combines a UV to near infrared Si photodiode with a thermoelectric cooler. A thermistor is also included in the same package to sense the Si photodiode chip temperature. This allows stable operation over long periods of time, making this sensor suitable for low-light-level detection where a high S/N is required. The S2592-04 is hermetically sealed in a TO-8 package.

Features
– High S/N
– High UV sensitivity
– Built-in thermistor allows stable operation
