In military applications detection signals are typically very weak. Now that eye-safe pulsed laser diodes have just recently been introduced at 1550 nm for rangefinding applications.
New InGaAs photodiodes detect in the spectral range from 1000 nm to 1650 nm.
The appropriate detector will follow.
Maximum Sensitivity at 1550 nm
These new InGaAs photodiodes detect in the spectral range from 1000 nm to 1650 nm. They peak at 1550 nm!
The so-called IAG series offers much more: In addition to the reliable detector areas of 80 µm and 200 µm, an XXL version is also produced. The massive 350 µm diameter of this series almost overshadows its other features:
- Large bandwidth up to 2.5 GHz
- Smallest dark currents possible
- NEP of typically 0.01 pW/sqrHz
- Damage threshold > 200 kW/cm²
Robust and extremely dynamic, these APDs are delivered in a TO-46 housing. The option of customer-specific solutions is always available with us!
