1. Simultaneous Multi-band Imaging
The Multi-Color Imager enables simultaneous multi-band observations, acquiring images in the g, r, i, and z bands at the same time. This capability significantly improves photometric observing efficiency by eliminating sequential filter switching.
2. System Configuration
- Beam-Splitting Optics
A beam-splitter assembly consisting of three dichroic mirrors directs incoming light into separate optical paths. Each path is equipped with a dedicated filter placed in front of the CCD detector, allowing simultaneous imaging in the target wavelength bands. - CCD Detectors
Three cryogenically cooled SI-1100 cameras equipped with E2V 4k × 2k CCD sensors (15 μm pixel size).
3. Control System
- All four observing bands are operated through a unified master control software responsible for synchronized image acquisition.
- The system is being developed to support remote and automated observing operations.
4. Current Status
- CCD units are being prepared for long-duration low-temperature operational testing.
- A dedicated mounting frame and center-of-gravity adjustment platform are under design to improve balance and mechanical stability.
- Cable routing solutions, including drag chains and fixed anchor points, are being planned to prevent interference and excessive bending during instrument rotation while maintaining cooling and vacuum efficiency.
- Routine inspection procedures and replacement component lists are being established in accordance with observatory operational protocols.
