LMT® PHOTOMETER HEADS
Sensor family for a variety of measurements tasks in photometry or radiometry
Photometer heads with aperture diameter ranging from 5 to 30 mm are available, from 10mm upwards LMT Mosaic Filtering® may be applied.
All LMT sensors can be configured as system photometers, e.g. in combination with a pre-amplifier allowing a cable length of 50m or more, for instance in the frame of far-field goniophotometry.
Options
- Thermostatic stabilisation for enhanced readout precision or outdoor use
- Cosine adapter for cosine-true response of spatial behaviour
- Ez or Esz adapter in combination with P10-FC0 for measurement of (semi-)cylindrical illuminance
- Precision aperture P11 F0T-AG with a certified area of 100 mm² traceable to an NMI.
- Fixture with gimbal and/or sprit level for precise horizontal alignment
- Housing for outdoor installation with sensor protected by a glass dome against adverse wheather conditions.
On request photometer heads with adoption to the spectral luminous efficiency curve V'(l) for scotopic vision or approximating the weighting functions for photosynthesis (Esy) and for Bilirubin dissociation (Ebi) can be delivered.
