Design and integration details
- Liquid-nitrogen-cooled side-window InSb detector family.
- General-purpose current-output detector or high-speed voltage-output detector with integrated preamplifier.
- The high-speed model uses a 20 MHz preamplifier for nanosecond time-resolved measurements.
Application and connection notes
- A preamplifier and lock-in amplifier improve sensitivity for the DInSb5-De02.
- The source states that one liquid-nitrogen fill can maintain operation for approximately eight hours.
- Standard configuration is for a manual Omni-λ slit; contact us for motorized-slit integration.
