Buying Photodetectors

Infrared Unleashed

Our D2250 2.2–5.0 µm single wavelength detector is super-fast (up to 10 GHz bandwidth) and ultra-sensitive (NEP of a few fW/√Hz).

Our D2250’s are based upon a new measuring paradigm where mid-infrared light is converted into near-visible light and then measured with conventional near-visible detector technology.

Ultrafast photodetectors from ALPHALAS for measurement of optical waveforms with rise times starting from 10 ps and total spectral coverage from 170 to 2600 nm (VUV to IR) have bandwidths from DC up to 30 GHz. Configurations include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. The UV-extended versions of the Si photodiodes are the only commercial products that cover the spectral range from 170 to 1100 nm with a rise time < 50 ps. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the highest speed operation, while a high impedance load generates large amplitude signals. Applications include pulse form and duration measurement, mode beating monitoring and heterodyne measurements. Balanced photodiodes complement the large selection of more than 70 unique models.

FEMTO offers a wide range of very low-noise photodetectors. They offer bandwidths up to 2 GHz and gains up to approximately 10¹² V/W, resulting in measurement ranges from fW to mW. The NEP reaches a minimum of 0.7 fW/√Hz. There is a choice of Si or InGaAs photodiodes covering a wavelength range from 190 nm to 1700 nm, with either a free space or fiber input (FC/PC, FC/APC). Many types and models are switchable in gain and bandwidth and can be controlled manually or remotely via PC. Customized models are available upon request.
