| Abstract: |
We developed a 15-band simultaneous imager called a Dichroic Mirror Camera (DMC) using many dichroic mirrors. DMC covers a wide optical wavelength range (390-930nm) in 15 intermediate bands. We successfully got the first light at the 1.5-m Kanata telescope in May 2007. The field of view is about 4 arcmin in diameter with 0.27arcsec/pixel. Optical performance of DMC was satisfactory to carry out astronomical observations. We also discuss possible extensions of DMC as a spectrograph with a grism mode and multibands Fabry-Perot mode as well as future photometric redshift surveys. |
