WEAVE is a new multi-object survey spectrograph for the 4.2-m William Herschel Telescope (WHT) at the Observatorio del Roque de los Muchachos, on La Palma in the Canary Islands. It will allow astronomers to take optical spectra of up to ~1000 targets over a two-degree field of view in a single exposure (MOS), or to carry out integral-field spectroscopy using 20 deployable mini integral-field units (mIFUs) or one large fixed integral-field unit (LIFU). WEAVE's fibre-fed spectrograph comprises two arms, one optimised for the blue and one for the red, and offers two possible spectroscopic resolutions, 5000 and 20,000.

WEAVE Spectrograph, Optical fabrication

We are getting ready to receive the blanks for red camera lenses 2, 3, 4 and 5.

Have you ever wondered how the curvature of a lens is generated? Look, here we are generating a curvature!

The test plates of the red camera lenses 2 and 3 are now being manufactured!

We have reached a lower surface roughness spec of a Rq 0.001 um for Red Camera Lenses 6, 7 and 8.

We finished the first face of the red camera lens 8!

Another test plate is ready! Lens 6 can now be tested!
