Star Targets are ideal for identifying focus errors, astigmatism, and other aberrations existing in an imaging system. Our 60mm diameter (#58-832 and #58-833) targets feature an unresolved core of 100μm and are ideal for high-resolution or high magnification imaging systems. Both targets are chrome on glass. Star Targets, in the 4” x 4” size, are available as chrome on glass (#46-247) or photo paper (#46-246), feature an unresolved core of 2.7mm, and are designed for mid- to low-range spatial frequencies common in macro imaging systems. These targets have a frequency range at target center (lp/mm) of 7.14-229.2.
