  • Acquisition Camera Ring Set: 13mm Backfocus

    This acquisition camera ring set is the standard-issue adapter for Shelyak Lhires III and LISA spectroscopes, designed to position a camera sensor at the precise backfocus distance between 9.15mm and 13.15mm. It is the factory component for mounting the acquisition (CCD) camera on the camera port, placing the sensor at the focal plane of the spectrum.

    Standard-Issue Adapter for 9.15mm to 13.15mm Backfocus

    Achieving the correct camera spacing is critical for a sharply focused spectrum. This ring set is the original part supplied with new Lhires III and LISA instruments, built specifically to accommodate acquisition cameras with a backfocus from 9.15mm to 13.15mm. Whether you have misplaced the original adapter or need a spare, this component restores your instrument to its factory-specified configuration for reliable performance.

  • What is the purpose of the Shelyak 13mm Acquisition Camera Ring Set?

    This ring set is an adapter designed to mount the acquisition (CCD) camera onto a Shelyak Lhires III or LISA spectroscope. Its primary function is to set the camera sensor at the correct backfocus distance, which must be between 9.15mm and 13.15mm, for a sharply focused spectrum.

    Which spectroscopes is this 13mm ring set compatible with?

    This adapter is specifically designed for and supplied as standard with the Shelyak Lhires III and Shelyak LISA series of spectroscopes. It is not intended for other models or brands.

    My acquisition camera has a backfocus of 12.5mm. Will this adapter work with my Lhires III?

    Yes. This adapter is designed for any camera with a backfocus between 9.15mm and 13.15mm. Since 12.5mm falls within this range, this is the correct adapter for connecting your camera to a Lhires III or LISA spectroscope.

    I lost the original camera adapter for my Lhires III spectroscope. Is this the correct replacement part?

    Yes, this is the official, standard-issue adapter that is supplied with new Lhires III and LISA instruments. If your original part is missing or damaged, this is the correct factory replacement.

    Why is the 9.15mm to 13.15mm backfocus critical for a Lhires III or LISA spectroscope?

    This distance places your acquisition camera's sensor at the focal plane of the spectrum. If the spacing is incorrect, the spectrum cannot be brought to sharp focus.

    Can I use this ring set to mount my main science camera to the spectroscope?

    Yes. In Shelyak's terms the acquisition camera is the CCD camera that records the spectrum, and this ring set mounts it on the camera port of the Lhires III or LISA. The guide camera uses a separate port.
