2.5 ADJUSTING BEAM DIVERGENCE
Megaray’s beam divergence (angle) is adjusted by sliding the lens housing (Figure 16) forward
or backward.
2.5.1 Decreased Beam Divergence
As the lens housing moves forward (Figure 16 - A), the beam divergence decreases to a
minimum of 2°. Maximum light intensity is obtained at this angle.
2.5.2 Increased Beam Divergence
As the lens housing is moved backwards (Figure 16 - B), the beam angle increases until the
maximum beam of 6° is achieved.
