增强型EM CCD
The latest generation ProEM-HS: 512BX3 delivers > 60 full frames per second at 20 MHz (twice the previous generation ADC speed).

增强型EM CCD

The latest generation ProEM-HS: 512BX3 delivers > 60 full frames per second at 20 MHz (twice the previous generation ADC speed). It provides this performance without compromising on the other features researchers expect from Princeton Instruments: lifetime vacuum guarantee, low noise, ultra-high frame rates, time stamping etc. In fact, our engineers improved all around performance including the low noise, standard CCD operation for even lower noise operation.

增强型EM CCD

  • Patented eXcelon3 technology for enhanced QE (> 95%) and
  • the best fringe suppression
  • 20 MHz readout speed
  • 300 ns vertical shift rate
  • Ultra-high speed readout mode for >1000 fps in imaging mode and >10,000 fps in spectroscopy mode
  • Improved noise (~4.9 e- rms @ 1MHz) in traditional CCD mode
  • Fully compatible with our award winning IsoPlane spectrographs and LightField software

All-metal seals: Good vacuum is key to achieving deep cooling and consequently low dark noise. Traditional epoxy based seals degrade over time and compromise vacuum performance due to out-gassing. In contrast, Princeton Instruments’ proprietary all-metal sealed design provides highest level of vacuum performance, year after year. Even the vacuum window, the only optical surface in the optical path, is brazed (fused at molecular level) to the vacuum chamber.

Permanent vacuum guarantee: ProEM comes with PI’s lifetime vacuum guarantee. It is the only such guarantee of its kind in the industry and is backed by advanced vacuum technology and thousands of cameras in the field!

Options: Options galore! Say goodbye to compromises. ProEM delivers the highest performance using air, liquid or a combination thereof.

Air only: Most convenient of all - just connect the camera and go. ProEM is cooled using a built-in, low-noise fan.

Liquid only: In vibration sensitive applications such as microscopy, any moving parts such as internal fans create vibration. Astronomy applications require that there be no air turbulence around the escope optics which can cause de-focusing. Liquid-only cooling method eliminates heat and vibration while achieving maximum cooling performance. This is superior to temporarily turning off the fan, which compromises the cooling stability over long periods.

Air+Liquid: When your application requires all the cooling and the lowest dark noise - use cold liquid circulation and the built-in fan in ProEM to get even better cooling and reduce dark current.

Low Noise
PINS (Princeton Instruments Noise Suppression technology): Princeton Instruments' engineers have used the next generation electronics to get the lowest possible noise levels in ProEM. In EM mode, the ProEM delivers the lowest starting read noise of any camera in the market, an advantage considering only a small amount of EM gain is required to achieve <1 e- rms effective read noise.

For traditional readout port, the camera delivers 3 e- rms read noise at 100kHz, an unparalleled performance. Whether it is fast or slow application, the ProEM delivers the lowest noise combination ever achieved. Part of the technology also includes proprietary methods to reduce clock-induced charge –an unwanted noise source in EM applications requiring single photon detection. It is reduced to 0.002 e-/p/frame with careful optimization of clock timing and voltage levels on every camera.

Sensitivity
eXcelon3 back-illuminated EMCCD: At the heart of ProEM is a back-illuminated EMCCD with patented eXcelon3 sensor technology that delivers greater than 90% quantum efficiency, single photon sensitivity, and reduced fringing (etaloning). No other EMCCD sensor can claim to have such proven performance.

Options
Numerous options - No more compromises! ProEM delivers the highest performance using air, liquid or a combination thereof. The cameras can be cooled below -90° C for the lowest dark noise. For traditional readout port, the camera delivers 2.5 to 3 e- rms read noise at 100 kHz, an unparalleled performance. Whether it is fast or slow application, the ProEM delivers the lowest noise combination ever achieved.

Part of the technology also includes proprietary methods to reduce clock induced charge –an unwanted noise source in EM applications requiring single photon detection. It is reduced to 0.005 e-/p/frame with careful optimization of clock timing and voltage levels on every camera.

Speed
Video frame rates and better: ProEM provides better than video rate even at full resolution (512 x 512). But if you need hundreds of frames per second, a combination of binning and region of interest (ROI) can be used. For even higher frame rate, a “high speed” camera mode allows 3 to 5 times higher frame rate when only a partial area of the CCD is illuminated.
