iDus Spectroscopy CCD

DU401

The 401 CCD camera with USB connectivity provides thermoelectric cooling to -100˚C, enabling negligible dark current and greatly improved air cooling capabilities. Thiscamera offers the best price/performance for a wide range of spectroscopy applications. The 1024 x 127 array with 26μm² pixels offers the best dynamic range versus resolution.

Technical Specifications

• What does this specification mean?Active Pixels

  1024 x 127

  The smallest elements of a CCD detector grid.

• Pixel Size (µm)

  26

• Image Area

  26.6 x 3.3

• Pixel Well Depth (e^-, typical)

  Minimum: 180000
  Typical: 300000

• What does this specification mean?Register Well Depth (e^-, typical)

  1000000

  The register well depth that is actually accessible by the CCD system is dependant on the sensitivity setting.

• What does this specification mean?Max Spectra Per Sec

  81

  Based on a Horizontal Pixel Readout of 100KHz and a vertical pixel shift of 13μS. Vertical speeds are software selectable. All sensors are guaranteed to operate at 13μs vertical pixel shift and most can be clocked faster. At these faster speeds there may be some degradation of Charge Transfer Efficiency (C.T.E.). FVB is short for Full Vertical Binning (Binning is a process that allows charge from two or more pixels to be combined on the EMCCD-chip prior to readout).

• Read Noise (e^-, typical)

  3 @ 33 kHz

Features and Benefits

• Peak QE of 95%

  High detector sensitivity.

• UltraVac™

  Critical for sustained vacuum integrity and to maintain unequalled cooling and QE performance, year after year.

• Simple USB 2.0 Connection

  USB 2.0 connection direct from back of the camera – no controller box needed!

• Single Window Design

  Delivers maximum photon throughput.

• Unique Fringe Suppression Technology™

  Eliminates fringing (etaloning) effects.

• Front or Back Illuminated Sensor

  Offers the ultimate in price/performance options.

• Software Selectable Pre-Amplifier Gain (PAG)

  Offers best choice for noise and dynamic range

• Min Operating Temp of -100˚C with TE Cooling

  Negligible dark current without the aggravation or safety concerns associated with LN2.
