Spectral Response Range:
|
|
The spectral response range of incident light the photodiode detects, also called wavelength range.

Search Logic:
|
|
User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

|
| |
Active Area Diameter or Length:
|
|
The active area of the detector. If the active area is a circle, the diameter, otherwise the length of the active area.

Photodiode Material
|
|
|
| |
Your choices are...
|
|
|
| |
Silicon
|
|
Silicon photodiodes are the most common detectors of light used in instrumentation. The spectral response covers the UV, the Visible and the near infrared.
|
| |
Indium Gallium Arsenide
|
|
Indium Gallium Arsenide (InGaAs) photodiodes are similar to silicon in performance and are used mostly in the near IR range of .8µm to 2.5µm. The noise performance does not match that of Si.
|
| |
Germanium
|
|
Germanium photodiodes are similar to silicon in performance and are used mostly in the near IR range of .8µm to 2.5µm. The noise performance does not match that of Si.
|
| |
Gallium Nitride
|
|
Gallium Nitride (GaN) photodiodes offer UV sensitivity while they reject VIS-IR background, thus facilitating measurements in this difficult wavelength range.
|
| |
Silicon Carbide
|
|
Ultraviolet radiation is usually detected with a detector made from a wide bandgap semiconductor such as Silicon Carbide(SiC). The short wavelength UV radiation is absorbed by the SiC generating additional charge carriers in the material. Longer wavelength visible and infrared radiation cannot bridge the wide bandgap, and the SiC detector is blind to these wavelengths.
|
| |
Other
|
|
Any other photodiode material not listed.
