< Mercury Lamp Holder Jig >
The mercury lamp holder has been improved since November 2009 (left one in the photo below). The
cell window of the mercury lamp releases a long horizontal beam of light depth wise, minimizing the
installation error. Since frosted glass is mounted inside the cell, light distribution and intensity are
suitable for the adjustment of the optical axis.
The new-model mercury lamp holder consists of the following parts.
