Ordering
How to compile your order numbers:
Different components such as detector material, packaging and size combine to create Judson's detector model numbers. Below is the information you will need to specify exactly the detector you require. Judson's applications engineers and customer service representatives are also available to assist you in choosing the proper detector.
Some examples:
- J16-5SP-R02M
- J12TE2-66D-R250U
- J15InSb-M204-S01M
Please read the following information to see how these model numbers were "built". The order portions are color coded above.
Material (Detector Series)
| Detector Material | Series |
| Germanium (Ge) | J16 |
| Indium Gallium Arsenide (InGaAs) | J22, J23 |
| Indium Arsenide (InAs) | J12 |
| Lead Sulfide (PbS) | J13 |
| Lead Selenide (PbSe) | J14 |
| Indium Antimonide (InSb) | J10 |
| PC Mercury Cadmium Telluride (HgCdTe) | J15 |
| PV Mercury Cadmium Telluride (PVMCT) | J19 |
This "series" designation makes up the first part of the model number as signified in the GREEN part of the examples above.
Dewar / Package Style
You may choose which dewar type or style you would like your detector to be "packaged" in. Judson supplies a large variety of packaging for our infrared detectors. Please review the website information for your particular detector material to see the choices of dewars and packages. Some of the most commonly used combinations are as follows:
| Detector Material | Most Commonly Used Packages |
| Germanium | 18A, 5SP, 8SP, P1 |
| Indium Gallium Arsenide | 66G, 3CN, 5I, 18I |
| Indium Arsenide | 18C, 37S, 66D, 3CN |
| Lead Sulfide | TO-5, TO-8, TO-3, TO-37 |
| Lead Selenide | TO-5, TO-8, TO-3, TO-37 |
| Indium Antimonide | M204, M200, M205 |
| Photoconductive Mercury Cadmium Telluride | M204, 66C, 3CN, 66GE |
| Photovoltaic Mercury Cadmium Telluride | 3CN, 66C, 66D, 37S, 18C |
The second part of our model number is the package. Please see the RED part of the above examples.
Active Area Size
Our detectors are available in sizes ranging from 0.25mm to 10mm. They can be round as signified by an "R" in the model number or square as identified by an "S". Detectors are measured in microns ("U") or millimeters ("M"). Thus, a 1/4 millimeter (250 microns) round detector would be signified as an R250U. The BLUE segment of the examples shows the size and shape of the detector.
Thus, the examples shown above are identified as follows:
| J16-5SP-R02M | J16 Germanium | 5SP Package | Round active area; 2mm diameter |
| J12TE2-66D-R250U | J12TE2 Thermoelectrically cooled Indium Arsenide | 66D Package | Round active area; 250µm diameter |
| J15InSb-M204-S01M | J15InSb Mercury Cadmium Telluride / Indium Antimonide "Sandwich" | M204 Dewar | Square active area; 1mm x 1mm |
