Description/Uses:
- Set of four fixed length M54x0.75 thread extension rings/barrel spacers
- Fixed length spacers: 5mm, 10mm, 20mm and 30mm
- Allows you to securely set the spacing between M54 thread components such as cameras, reducers, correctors, filter wheels, etc.
- Spacers can be stacked together in various combinations to achieve spacing in several combinations ranging from 0.20" - 2.56" (5mm - 65mm)
- Each spacer has 54mm threads (male on one side and female on the other)
Features:
- Precision machined from aluminum and black anodized
- Black matted finish inside to reduce stray light reflections
Specifications:
All Spacers
- Thread Specification (External Thread) = M54x0.75 Male
- Thread Specification (Internal Thread) = M54x0.75 Female
- Clear Aperture = 2.00" (50.9mm)
- Maximum Outside Diameter of Barrel = 2.23" (56.8mm)
- Combined Weight of All Included Items = 2.2oz (64g)
Fixed Length Spacers
- Total Spacer Lengths = 0.20", 0.39", 0.79" and 1.18" (5mm, 10mm, 20mm and 30mm)
- Length of External Male Thread = 0.20" (5mm)
- Lengths of Internal Female Thread = 0.18" (4.6mm) in the 5mm spacer and 0.24" (6mm) in the other spacers.
- IMPORTANT NOTE: Since the female thread length of the 5mm spacer is shorter than the male thread lengths of the other fixed-length spacers by 0.6mm, the total extension provided will be longer by 0.6mm if you affix the 5mm spacer to the male thread of the others (i.e., the effective spacer length becomes 5.6mm). You can maintain its 5mm length by attaching the male end of the 5mm spacer into the female end of the others instead.
