2" 90° Diagonal	$210.00
[DSC-2001]

The 2" Enhanced Aluminum mirror coating provides a 96% reflective surface across all but the extreme ends of the visual spectrum. The enhanced coating provides extra reflectance versus competing standard aluminum coatings. The final coating stage applies a tough overcoat to protect the aluminum. The diagonal body has the same features as the Everbrite. The Enhanced Aluminum 1¼" diagonal features a 96% reflective mirror coating. All diagonals feature brass clamp rings and filter threads. The Enhanced Aluminum diagonals are good budget alternatives, especially where a prism diagonal might otherwise be considered.
