ABSTRACT:
An adhesive positions a beam shaping element in such a manner as to satisfy the following relational expressions (1) and (2):in-line-formulae description="In-line Formulae" end="lead"?0<L≦ΔWA/(α·Δ·SAS) (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?SAS=1000(0.5 m2+1.5m−2)[mλ/mm] (2),in-line-formulae description="In-line Formulae" end="tail"?if it is assumed that m is the beam shaping magnification of a beam shaping element, L[mm] is the distance from a light source side surface of the beam shaping element to a center position of the adhesive, α[1/K] is the linear expansion coefficient of a light source retaining holder, ΔWA[mλ] is amount of astigmatic aberration caused by the beam shaping element, and ΔT[K] is an environmental temperature variation amount.
