Choosing the right FINN for your needs is easy. The following chart will show you our recommended FINN to use for detecting each type of LED colour emission:
| LED colour | Nominal Wavelength | FINN Type | Sensor
Peak Sensitivity Wavelength / 50% bandwidth |
| Red | 655-700nm | Red / TC3001 | 660nm / 615-705 nm |
| Orange | 605nm | Red / TC3001 | 660nm / 615-705 nm |
| Yellow | 585nm | Green / TC2901 | 540nm / 505-575nm |
| Green | 560nm | Green / TC2901 | 540nm /505-575nm |
| Blue | 450-500nm | Blue / TC2801 | 460nm / 415-505nm |
| Any / Clear | N/A | Clear / TC8704 | 560nm / 400-680nm |
Notes:
• The clear sensor can be used to detect both elements of a
bicolour LED turning on.
• These FINNs are available for SMT LEDs. Side emitting LEDs will
require a little more fixture setup.
