The diagonal housings and mirrors are produced specifically for Denkmeier Optical by William Optics. The modular nature of the William Optics diagonal plus the outstanding attention to detail convinced them that a joint effort would result in a very amazing product. The mirrors on all Denkmeier Power x Switch Diagonals are figured to a Lamda/10 flatness and are 10mm thick.

The Power x Switch... The Power x Switches feature 2" format, fully multi-coated (FMC) optics that deliver sharp, contrasty images. The Power x Switches are machined here in the USA and assembled in the Denkmeier Maryland facility. They undergo rigorous quality control.

Ever look at the Dumbell (M27) in an SCT with a focal reducer? Normal F/10 power? What about with a 2X Barlow? Move on to The Ring and M13. Care to do the same? We all know that threading a reducer on and off for every object is not realistic, especially when it starts getting cold... or when it's warm and the bugs are biting! Now you can and will examine every object at three magnifications because it is instant and easy.

Denkmeier Product Number: PSDS1

Customer Note: All Denk Power Switch Star Diagonals were compacted with the "armless" Power Switch Carrier design. Denkmeier introduced this more than one year ago! They are in the process of changing their manual photos. If you order any Power Switch Star Diagonal, you will receive the compact armless version.
