Extension Ring type ZR55

for M55x0.75

• Black anodized
• Different length from 15 to 60 mm

For large image scales up to macro imaging (magnification about 1:1), the integral lens focus extension or the extension of the focus adapter is usually not sufficient. The camera tube is then lengthened with extension rings to fit.

The indicated lengths are optical path lengths. The mechanical dimensions can be found in the dimensional drawings. Each extension ring has an inner thread and an outer thread at the opposite end.
