LiCal organizes the first call for the characterization and testing of the lidar optical components, in coordination with the LiCalTrain 1^st workshop (23-27 May 2016). Participants to the training can bring components and participate to the laboratory tests, however the call is not restricted to those. Components can also be sent via carrier.

Applications should be submitted to nnicol@inoe.ro by 31^st of March 2016, using the TNA request form LiCal-TNArequest-CTW1.

Main focus: a) interference filters center wavelength, homogeneity, bandwidth fwhm with an accuracy <0.1nm at 0 degrees; b) spatial homogeneity of the linear polarization filters used in the depolarization channels: extinction ratio (1mm spots), overall extinction ratio; c) emission optics transmittance and reflectance parameters (Rp, Rs, Tp, Ts), retardation at 45 degrees incidence angle +-5 degree (accuracy 0.1 degrees and resolution 0.5 degrees).

Target users: ACTRIS-EARLINET and external lidar operators, manufacturers of optics for lidar, lidar integrators
