2 M TELESCOPE - Near IR Imager

The near-infrared imagerThe near-infrared imager is built around a 512 X 512 HgCdTe array of 18 micron pixel size. The image scale of this instrument will help in subarcsec imaging and reaching out to fainter limits. The instrument has two cameras, one 1:1 camera (Camera-A) and another 0.5:1 camera (Camera-B) giving a wider field.

THIS INSTRUMENT HAS BEEN REPLACED BY THE TIRSPEC. The NIR IMAGER IS NO LONGER AVAILABLE FOR OBSERVATIONS
