4.2 Mounting the MFS Receiver Sensor
- Minimum bending radius:
ƒ
Short-term 10 mm
ƒ
Permanently 50 mm
- Numerical aperture: 0.47
- Attenuation at 660 nm less than 220 dB/km (typically 190 dB/km)
Position the sensor over the optical center of the LEDs.
Maintain a distance of 2 to 15 mm between the LED and the sensor.
i
The distance depends on the luminosity of the specimen and the sensor used.

The intensity of a test depends on the working distance and offset of the LED with respect to the sensor. The permissible
offset depends on the measuring spot of the sensor. For more information on the working distance and on the measuring
spot, please consult the technical data
, see 2.5.2 . Several MFS receiver sensors are available for detecting the light , see A
