Star Targets

產品名稱 : Star Targets
產品說明 :
Star targets are ideal for identifying focus errors, astigmatism, and other aberrations existing in an imaging system. We have several targets to choose from. Our 60mm diameter (UNI58832 and UNI58833) targets feature an unresolved core of 100μm, and are ideal for high-resolution or high magnification imaging systems. Both targets are chrome on glass. Our 4” x 4” targets, available as chrome on glass (UNI46247) or photo paper (UNI46246), feature an unresolved core of 2.7mm, and are designed for mid- to low-range spatial frequencies common in macro imaging systems.

● Ideal for Detection of Focus Errors and Astigmatism
