200 LPI Large Ronchi Screen

Return to list

Requested by one of our customers who wanted an even finer screen than 133 LPI. This is a unique 200 LPI Ronchi grating with the equally-spaced black lines taking up 50% of the area. It is mounted in a wide-open 60 mm x 60 mm medium-format slide holder for protection and ease of use. The outer dimensions measure 2.75" square.

This quality Ronchi screen is produced on high-resolution, high-contrast film to give sharp, solid lines so you can get the best readings possible when testing your telescope mirrors.
