LMT PHOTOMETER UNIT 1600 M

Goniophotometric illuminance measurement with auxililary photometer correction

This photometer unit has been designed for high speed, computer controlled measurements of lighting devices as part of LMT METROGON® goniometer laboratories.

It offers a 3rd “auxiliary” photometer input to be used for synchronised correction of orientation dependence according to CIE S025.

Features

• Precision Class L SP 30 SOT photometer head(s) with integrated amplifier(s) and calibration circuit, suitable for use with cable lengths of up to 50m
• SP 10 SCT auxiliary photometer head to be used in a fixed position close to the DUT, sychronously monitoring its light output while the intentsity distribution is being recorded
• Quality index for Adoption to V(λ) by means of LMT Mosaic Filtering® typically f₁^‘≤ 0.8%
• 4 ¹⁄₂ digit LED display with a sensitivity of illuminance down to 0.0001 lx (0.1 mlx)
• Up to 2+1 separate inputs, calibration in lx and cd
