Description

Proposals are sought by the Science and Technology Facilities Council (STFC, who are part of UKRI) for the supply of large aperture, anti-reflection (AR) coated, air-spaced mounted achromatic doublets for use in beam magnification and relay imaging telescopes for the high energy titanium-sapphire amplifier system as part of the EPAC Project.

Total Quantity or Scope

Supply of initial quantities of three types of doublets to the specifications detailed with the ability to purchase additional optics at a later date as described in Section 15 of the specification. A schematic diagram outlining the general design characteristics of each air-spaced mounted doublet is shown in Figure 1 of the specification. It consists of a pair of circular lens elements, referred to as ELEMENT A (negative meniscus) and ELEMENT B (positive meniscus), each of centre thickness Z thick, and separated by an air-gap (Z gap). The faces of each lens element are referred to as F1 to F4. Individual lens elements will be secured independently within a frame of fixed outside diameter providing a minimum clear aperture for optical transmission of a high energy laser beam. There is an initial total of 10 doublets to be procured and delivered by March 2023, however, earlier delivery is preferred.
