Price Inquiry (PQ) for a set of phase plates: thin silica elements engraved by lithography (or modified by another process) to produce a deterministic optical path difference (OPD). The scope of work includes the production, test, and delivery of:

1. 10 elements in total, each with an clear aperture of about 50 mm diameter. A central disk-like pattern shall be produced on each of them with different sizes (0.25 to 5 mm) and different depths, producing optical path differences in the range of around of around 220 nm to 450 nm.

2. 6 elements with 80 mm diameter, including in them several 2 mm hexagonal flat, tilted surfaces, with a maximum depth of approximately 600 nm (300 nm OPD). A pattern with a black-chromium layer or an equivalent masking coating is applied on these. The accuracy of the patterns in dimensions and positioning on both item types is in the micrometric range. The OPD accuracy is 30 nm. All elements have an AR-coating optimised over the range [0.8-1.8] µm.

Contract is expected to be awarded in Q3/2022. The expected lead time is 12 months after contract kick-off.

Companies from the ESO Member States and Chile.

Price inquiry (PQ) for the production of six pyramid prisms. The scope of work includes the manufacturing, polishing, coating, and testing of 6 special prisms made out of the low dispersion glass S-FPL55. The prisms shall have a dimension of approximately 30 mm diameter and a height of 10 mm. The prims shall have a pyramid shape on one side, i. e. four facets converging in a tip under a shallow angle of approx. 4 degrees. The pyramid edge and tip shall be sharp with a thickness of 10 micron or less within the central few millimetres around the tip of the prism. The prism backside shall be flat. The final prisms shall receive an AR coating (wavelength range 1.4 – 2.3 micron).

In order to facilitate and verify the challenging edge sharpness, the contract has two steps. Phase 1: The production of two un-coated prototype prisms, which demonstrate the edge sharpness and full compliance with the specifications. Phase 2: In case of compliant proto-types, the remaining four prisms shall be manufactured and all six prisms shall receive the AR coating.

Contract is expected to be awarded in Q2/2022. The expected lead time of the delivery is 12 months for the whole project after contract kick-off.

The lens groups are asked to be delivered and verification tested, mounted in mechanical barrels. This contract comprises of 7 mounted lens groups, 1 unmounted large lens (diameter 250 mm), 7 flat mirrors, and one (non-polarizing) cube beamsplitter. The diameter range of the mounted lenses is between 20 mm and 80 mm and between 30mm and 160 mm for the flat mirrors.

Price Inquiry (PQ) for the production of 38 lenslet arrays for the Phasing and Diagnostic Station (PDS) of the ELT. Two types are needed:

§ 50 mm diameter lenslet arrays, with continuous or droplet-like patterns, with a pitch between lenslets (microlenses) of 270 µm, and a sag of about 2 µm (optical path difference of 1 µm), on a hexagonal pattern. A black-chromium or similar patterned coating is applied on top of half of the lenslet arrays, including a complex geometry, matching the hexagonal telescope primary mirror. This means half of the wafers will be delivered without black masking. Per lenslet array, about 15.000 subapertures are to be placed. 18 units will be purchased.

§ 25 mm diameter lenslet arrays on a rectangular 21 x 21 grid, with a 850 µm pitch, and about 50 µm sag on each lenslet. 20 units will be purchased. Lenslet arrays shall be produced, tested, and delivered with the test reports.

Contract is expected to be awarded in Q3/Q4 2022. The expected lead time is 12 months after contract kick-off.

Thickness of 50 mm. This optical element is used in reflection (in the wavelength range 500 nm – 2300 nm) and transmission (visible wavelengths only), with the transmitted optical beam of the order of 2-4 % and relatively stringent spectral and spatial uniformity for which the RFI is aimed to understand manufacturing constraints.

The RFI is planned to be followed by a Price inquiry. Contract is expected to be awarded in Q3/2022. The expected lead time is 12 months after contract kick-off.
