The first lens is a plano-convex and the second is a symmetrical biconcave in order to minimize manufacturing costs. The wavelength range for the corrector is 650-1800 nm. The material to be used is Heraeus HOQ 310, a low-OH IR-grade Fused-Quartz. Full details may be found via the Crown Commercial Services eSourcing Suite. Please note: Closing time for bids is 14/08/18 AT 14:00 hours. Do not apply directly to the buyer — Please follow the instructions provided in the additional text section(s).
