摘要
We developed a 15-band simultaneous imager called a Dichroic Mirror Camera (DMC) using many dichroic mirrors. DNIC covers a wide optical wavelength range (390-930 nm) 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. 11 aremin in diameter with 0.27 aresec/pixel. Optical performance of DMC was satisfactory to carry out astronomical observations. We also discuss possible extensions of DNIC as a spectrograph with a grisin mode and multi-bands Fabry-Perot mode as well as future photometric redshift surveys.
