| Résumé | The first light instrument on the Thirty Meter Telescope (TMT) project will be the InfraRed Imaging Spectrograph (IRIS). The IRIS On-Instrument Wavefront Sensor (OIWFS) provides diffraction limited wavefront sensing – in both tip/tilt and tip/tilt/focus modes – to NFIRAOS (Narrow Field InfraRed Adaptive Optics System). As part of the final design phase, we have further developed the optical and mechanical designs. We present recent changes to the optical design and the resulting performance and tolerance analysis. Changes include decreasing the field of view to 1.5×1.5 arcseconds (square) and moving the field lens to reduce vignetting of the science image. The mechanical design is being updated with more detail for the optical mounts. We present here example mounts and associated analyses and our plans for future prototyping. |
