Ring collar for laser pointer which mounts to 1/4-20 UNC male threaded end on standard tripod mounting. Uses captured 1/4-20 hex nut for mounting. Uses 1/4-20 UNC x 5/8 pan head screw and captured hex nut to secure laser pointer and allow for smaller OD laser pointer. Plan to use this with high speed trigger on DSLR camera for capturing water droplets.
