我見過有人在太空館用它來代替紅光 pointer

瑩幕 (Screen) 的設計是盡量把投射到它的光線反射給觀眾.
那次講座之後,不知有多少個觀眾的視網膜受到若干程度的損傷?

I strongly disagree people who uses green lazer as pointing device during lecture, it is completely ridigulous.

I think we should tell HKSM to give a guideline to the speaker not to use this harmful laser as pointing device. Red one will be good enough for the purpose.

Best Regards,

我寫了一張意見紙,放了入太空館的意見收集箱

我想他們已經注意到這個問題了.那支綠色激光 Pointer 應是講者自己帶入去的.

建議 在觀星營刊內加個「溫馨公仔」提醒不要亂用 laser pointer.
工作人員在現場向每位營友 再強調一次,吾係長氣,安全第一。

I myself use this setup to justify laserbeam safety. If the temperature rises (even very slightly), I regard it not SAFE to play.
