Summary:PURPOSE:To widen the working area of adjusting operation and to improve the operability by providing a transparent substrate containing a light emitting material which sends invisible light and emits visible light and a positioning member which positions the transparent substrate at right angles to the optical axis of laser light from the laser light emission system. CONSTITUTION:The substrate 12 is formed by incorporating the light emitting material which senses the ultraviolet laser and emits the visible light in transparent resin. A stand 13 is so positioned that the main surface of the held substrate 12 is invariably at right angles to the optical axis 15 of the ultraviolet laser. When the substrate 12 is irradiated with the ultraviolet laser light emitted by the laser light emission system 11, the light emitting material in the substrate 12 emits the visible light and a bright spot 16 having a diameter corresponding to the distance from the laser light emission system 11 appears on the substrate 12. An operator can observe the bright spot from the light irradiated surface side of the substrate 12 and its opposite side and necessary adjustments can be made by operating equipment for adjustment and the adjustment part of the laser light emission system 11. Consequently, the working area of the operator is wide and the operability is good.
