These standard grade of right angle prisms are similar to the Precision grade versions but with easier surface quality and angular specifications.  These standard range of right angle prisms are more cost effective than the precision grade of RA prism.  Various coatings can be applied to their faces.  Right angle prisms can be ground to smaller sizes or drilled and edged to create your bespoke custom prism.
