Making the invisible visible
Many things that are invisible to the human eye are visible in the infrared spectral range. The examples range from pressure spots on fruit, over cereal inspection, to production errors in silicon wafers and solar cells.
Polytec offers you cameras, and display devices for short-wavelength to long-wavelength infrared, including modern micro-bolometer cameras and OGI video cameras.
Classification of the infrared spectral ranges
| Designation according to DIN/ISO | ISO 20473 | DIN | Wavelength range (DIN/ISO) | Wavelength range (anglo-american) | Anglo-american designation |
|---|---|---|---|---|---|
| near infrared | NIR | IR-A | 780 - 1400 nm | NIR (near infrared) | |
| NIR | IR-B | 1,4 - 3 µm | SWIR (short wave infrared) | ||
| mid infrared | MIR | IR-C | 3 - 50 µm | 3 - 8 µm | MWIR (mid wave infrared) |
| MIR | 8 - 15 µm | LWIR (long wave infrared) | |||
| far infrared | FIR | 50 µm - 1 mm | 15 µm - 1 mm | FIR (far infrared) | |
Polytec uses the internationally common anglo-american classification.
