1. Mirror Coatings for Array Telescopes
Bte has know how and capacity 1

2. Metallic Mirror Coating:
Mainly Aluminum plus dielectric enhancement
Enhancement tuned to spectral region of interest (e.g. Blue/UV for Cerenkov radiation) 2

3. Dielectric mirror coating:
Multilayer system adapted to reflection range and angle of incidence
Multilayer design makes selection of reflectance band and suppression of undesired radiation possible 3

4. Quick and cost effective coating campaigns (e. g
Quick and cost effective coating campaigns (e.g. 382 mirrors for HESS) require
Big sized coating machines
Know how for achieving reproducibla and homogeneous coatings
Know how in substrate handling and preparation 4

5. Conclusion:
Bte has know how, capacity and experience in metal and dielectric coating of a series of telescope array mirrors for reasonable prices in a reasonable time frame. 5
