Notes:
1. Front to back thickness of the filter wheel excluding motor, in inches (mm).
2. Filters are round unless followed by SQ, indicating square.
3. Typically the camera side of the filter wheel.
4. Typically the optical side of the filter wheel (for example, lens or telescope).
5. PL OBFD = Optical back focal distance (image plane of CCD to cover side of filter wheel) for PL or ML camera with 65 mm shutter. See note 14.
6. ML OBFD = OBFD for standard 25mm or 45mm MicroLine with FLI dovetail + filter wheel. See note 14.
7. Carousel will accept either 2” or 50 mm filters.
8. May accept thinner filters with an O-ring; however, the O-ring will reduce the aperture.
9. May be made for 25 mm / 1” filters on special request.
10. BP = bolt pattern
11. Because the carousels overlap, one position in each is normally left open. For example, eight + two open positions for the CL-1-10.
12. ZTA = CenterLine Zero Tilt AdapterTM
13. Assumes CL ZTA flange on front of camera. Add 9.22mm for CL adapter to FLI dovetail (AD70 or AD71).
14. For most materials, subtract 1/3 of the thickness of any filter (e.g. subtract 1mm for a 3mm thick filter) as well as 1/3 of the thickness of any cover glass on the CCD.
