Following minor modifications to the position of the optics to allow for the dichroic to be placed, the current version is now V_18 (produced September 1998). A ZEMAX file is on the project page. Removal of the dichroic causes a simple lateral shift of the collimated beam. At our request Damien Jones has placed the grating assembly mid-way between the shifted and unshifted position.
