ASA 1.8X Barlow-Corrector - 2"

General Information on ASA Correctors...

For photographic correction of the Field of View (FOV) ASA produces correctors designed and calculated by Dipl. Phys. Philipp Keller. All correctors come with ample back focus to accommodate all common DSLR and CCD cameras.

ASA correctors are not calculated for a small spectral bandwidth of 450 to 650nm, but are optimized for a wider bandwidth from 400 to 700nm and above. Every lens used in ASA correctors is re-measured in radius and thickness. Any lens which lies outside of the strict ASA tolerances is discarded.

All ASA corrector tubes are manufactured in-house. Only high-grade aluminum is used and processed within a 0,01mm tolerance. ASA's strict quality control of lenses and exact processing of corrector frame and mounting ultimately guarantee high-end products which today already have become the reference class by which to measure excellence.

Every corrector is measured and tested within the system. For the highest grade lenses - deployed in professional Ritchey-Chr??tien and Cassegrain systems - the actual diffraction index of the delivered glass batch furthermore is measured. Should deviations in the material occur, the design will be adapted individually to ensure that the theoretical precision is also achieved in practice.
