Introduction
An optics experiment usually involves several optical elements which must be attached to an optic table. The K-Optics modular optic table can house a locking nut in any of its sockets where then an element can be mounted. The fork and spacer together are one of two K-Optics solutions with the other being the integral base. Both the fork and the various spacers are injection molded from engineering-grade glass-filled polymers in house at K-Optics.
Working Principle
The fork and spacer hold a tilt mount in place by applying pressure. This is done by placing a locking nut in a nearby slot and fixing the fork to it while its open end hooks onto the circular base. The circular base is grooved to rest in place on the spacer which does not allow free rotation of the base.
Spacers come in three variants: 0°,45°,90°. With the tilt mounts three possible angles of connection to the circular base, the spacers provide the user with an option for rotations in 15° increments.
The fork is available with either M6 or ¼” screw matching the options for the locking nuts.
