Laboratory optical integration
Photodiode Extended InGaAs 0.9 – 2.6 µm: Laboratory optical integration depends on preserving the optical budget through the complete path. The 0.9-2.6µm wavelength specification sets source and detector compatibility.
Photodiodes
The PDTM Series of Extended-InGaAs Photodiodes provides reliable NIR detection from 0.9 to 2.6 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.

Technical FAQ
Wavelength: 0.9-2.6µm. 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.
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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
