Photodiodes
Photodiode Extended InGaAs 0.9 – 2.2 µm
The PDTM Series of Extended-InGaAs Photodiodes provides reliable NIR detection from 0.9 to 2.2 µm with active-area options from 0.3 to 3.0 mm, allowing a clear speed–sensitivity trade-off (smaller areas = lower capacitance and faster response; larger areas = higher sensitivity). For plug-and-play use, an optional driver PCB integrates a low-noise transimpedance amplifier, eliminating external biasing and simplifying bench setup. Standard package and accessory options are available, with custom configurations on request.

System integration
Integration and compatibility
Use these checks to connect Photodiode Extended InGaAs 0.9 – 2.2 µm to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Wavelength and loss budget
- Wavelength: 0.9-2.2µm
- Check the Photodiodes passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
- Control interface
- Driver: No, Yes
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
Technical FAQ
Integration questions for Photodiode Extended InGaAs 0.9 – 2.2 µm
How should the Photodiode Extended InGaAs 0.9 – 2.2 µm be included in an optical power budget?
Wavelength: 0.9-2.2µm. Check the Photodiodes passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Does the Photodiode Extended InGaAs 0.9 – 2.2 µm require a controller?
Driver: No, Yes. Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
