Product Overview

The LAMBDA pixel detector is designed for high-end X-ray experiments, particularly at synchrotron sources. It achieves an extremely high image quality by combining effectively noise-free photon-counting operation with a small pixel size of 55 µm. For fast and time-resolved experiments, LAMBDA can be read out at up to 2000 frames per second with no time gap between images. But speed and resolution are not the only thing LAMBDA excels at, you can find a more detailed description of our systems features here. Upon request we also provide LAMBDA versions that can be operated in vacuum.

LAMBDA 60K

The LAMBDA 60K features an extremely small cross-section allowing it to squeeze into all but the tightest corners. It features a single Medipix3 chip allowing gap and seamless noiseless imaging without noise in 256x256 pixels at 2kHz frame rate.

LAMBDA 350K

LAMBDA systems with Gallium Arsenide (GaAs) or Cadmium Telluride (CdTe) sensor are available in a special 350K version using a monolithic, gapless sensor mated to 2x3 Medipix3 chips. It uses the same housing as the LAMBDA 750K version.

LAMBDA 750K

Our standard, full size LAMBDA 750K systems feature up to 512 x 1536 pixels and offer superior performance in a user friendly design. Like all our cameras it is capable of noiseless imaging at up to 2 kHz.

Key features:

Effectively zero noise (photon counting) 55 µm pixel size Up to 2000 frames per second Deadtime-free readout up to 1536 by 1536 pixels (85 x 85 mm 2 ) Energy binning capability

Products

Every version of the LAMBDA pixel detector is available with different sensor layers for different X-ray energy ranges. For hard X-ray detection, the GaAs and CdTe LAMBDA systems replace the standard silicon sensor layer in LAMBDA with a “high-Z” (high atomic number) sensor. This provides high quantum efficiency at high X-ray energies (75% at 40 keV for GaAs, and 75% at 80keV for CdTe), while retaining single-photon-counting performance and our high frame rate of up to 2 kHz.

LAMBDA 2M

Our largest routinely available LAMBDA systems tile multiple modules together to provide the largest possible detection area, while continuing to frame noiselessly at up to 2000 times per second. It is available with our full range of sensors, i.e., Silicon, GaAs and CdTe.

LAMBDA 250K

For applications that are restricted in maximum detector size, but require larger sensitive areas, noiseless imaging and 2000 fps, 250K systems increase the sensitive area by tiling 2x2 chips together without any gaps.
