IRIM – InfraRed Imaging Magnetograph

Lyot–Filter 1.56 m filter delivery delayed He 10830 Å filter requires new polarizers, stuck in NJIT

bureaucracy (open for bid, customs broker for Nanjing) Jun is preparing a paper for Optical Engineering on

achromatic wave plates for the next generation of Lyot–filters Fabry–Pérot Etalon

Extensive testing at CfSR Wenda is preparing a paper for Optical Engineering

NIR CMOS Camera Delivered to BBSO in September, tested at Rockwell but no

imaging data, yet Some software is still missing, Wenda will test the camera at

BBSO once the software is available Systems integration at CfSR in winter 2003/2004
