Help finding some specific elements for infrared (IR) sensor

  1. Jul 28, 2015 #1
    Dear Everyone,

    I'm searching for some specific elements for infrared (IR) sensor, such as Thermopile, Pyroelectric, Bolometer, MCT(HgCdTe), PbSe, or InSb sensors.

    Does anyone know how to get these kinds of elements ?
    ( I need some information about the manufacturers...)

    The elements are required to match the specifications(a. to e.) as follows:

    1. Thermopile array #1:

    a. Pixel pitch: 0.6 mm
    b. Array type: 2 x 4 or 4 x 4
    c. Sensing wavelength: 8 ~ 14 um
    d. Output type: analog for every element
    e. Element parameter:
    i. Element size: 0.5 mm x 0.5 mm
    ii. Sensitivity: 60V/W for 8~14u
    iii. Resistance: 80kΩ
    iv. Noise: 36 nV/√Hz
    v. D*: 0.9 x 108 for 1Hz
    vi. Time constant: < 6ms

    2. Thermopile array #2:
    a. Pixel pitch: 1.1 mm
    b. Array type: 2 x 2
    c. Sensing wavelength: 8 ~ 14 um
    d. Output type: analog for every element
    e. Element parameter:
    i. Element size: 1 mm x 1 mm
    ii. Sensitivity: 50V/W for 8~14um
    iii. Resistance: 80kΩ
    iv. Noise: 36 nV/√Hz
    v. D*: 1.3 x 108 for 1Hz
    vi. Time constant: < 10ms

    3. Pyroelectric array:
    a. Pixel pitch: 1.1 mm
    b. Array type: 2 x 2
    c. Sensing wavelength: 8 ~ 14 um
    d. Amplifier: with integrated voltage mode amplifier (ex. FET), every element
    e. Operate frequency: 1Hz ~ 5kHz
    f. Output type: analog for every element
    g. Element parameter:
    i. Element size: 1 mm x 1 mm
    ii. Sensitivity: 120V/W for 1kHz and 8~14um
    iii. Output impedance: ~100kΩ
    iv. NEP: 3.8 x 10-10W/√Hz
    v. D*: 2.5 x 108 for 1kHz
    vi. Time constant: < 25ms

    4. Bolometer array:
    a. Pixel pitch: 0.3 mm
    b. Array type: 8 x 8
    c. Sensing wavelength: 8 ~ 14 um
    d. Operate frequency: 1Hz ~ 5kHz
    e. Output type: analog for every element
    f. Element parameter:
    i. Element size: 0.25 mm x 0.25 mm
    ii. Sensitivity(before readout gain, 2V, 0Hz): 100,000V/W
    iii. NETD(f/1, 300K, 30Hz): < 10mK
    iv. D*: 8 x 108
    v. Time constant: < 15ms

    5. MCT(HgCdTe) or PbSe or InSb:
    a. Sensor type: one element
    b. Sensing wavelength: 3 ~ 5 um(cut-off λ= 4.9 ~ 6 um)
    c. Element parameter:
    i. Element size: 0.5 mm x 0.5 mm or 1 mm x 1 mm
    ii. D*: 8 x 108
    iii. Cooling: None or Built-in TEC type (Up to two TEC)

    Thank you so much !

    Best regards,
    Su-Te, Tasi.

    Have you tried this?

    It is so annoying to read FAQs. :oops:
