Central Obstruction Diameter at Susan Jaimes blog

Central Obstruction Diameter. According to the theory, annular aperture has mtf cutoff frequency identical to that of a circular aperture of the same diameter. Its minor axis is 65.8mm which is the actual central obstruction. Mirror mount has a plastic flange that surrounds the secondary mirror. The diameter of the primary mirror is. Following table gives the corresponding c.obstruction sizes for selected optics strehl values (in units of the aperture diameter). That makes it 46% by diameter or 21% by area. For example, a 2 diagonal in a 10 system obstructs 4% of the light, but is called a 20% central obstruction, because its effects on contrast. Figure 14.4 shows how resolution steadily improves with increasing central obstruction diameter. A typical sct will have a 35% to 40% co by diameter. Since central obstruction (co) results in. The larger number is by diameter and is the more important one as it affects contrast which affects perceived resolution.
