MULTIBEAM LENS DATA
The GJD multifunction lens fitted to the OPAL RFX detector produces 9 long range
beams and 9 medium to short range curtain beams. Movement across the beams
produces the best response and range, whilst movement towards the detector will be
less responsive.
When mounting higher than boundary fences rotate the module and mask off any
beams, either vertically or horizontally, that fall outside the area being covered. Use the
self-adhesive clear mask supplied to the rear, smooth side, of the lens and always
replace the correct way up as shown to obtain the exact beam pattern coverage.
