新手唔識想問下, 其實點解市面上好多紅點鏡個鏡片都會藍藍地色...?
係間廠既用料唔好定係有特別原因而造到佢藍藍地色?
因為睇番就算係真品都好... 有D廠或者有咁上下價錢既鏡都會有藍藍地既現象
唔通係特登?
如果想個鏡係唔會藍色既話, 應該買邊種款既鏡好?
新手無知, 真心求教

正常, 好多真鏡都有

應該係想令sight picture 同外界對比大D, 上眼快D

果d coating有d係用黎減少glare, 有d係用黎加強對比等等

如果只係一般防反光既 coating，只會反光睇個鏡面有D綠色，穿過個鏡睇係冇色，如果 coating 差D可能會有好淡既黃色（譬如 BSA），暫時未聽過藍色。做成好明顯藍色既應該係鏡片上面既半反光鍍膜，呢浸鍍膜係紅點鏡或西獨有，愛嚟反射粒 LED 既紅光，令鏡中間出現一個紅點。

我估係玻璃用料問題,經陽光折射,才有藍藍地色.

就好像我們看見,海水是藍藍地色.

不, 是故意用上有色玻璃, 藍好多的

亦有其他廠商用無色透明玻璃, 設計不同而已

copy from other forum//
On the highest quality sights and red-dot scopes (open type and closed type red dot SIGHTS), the "reflector lense" is often coated with a colored polarizing film. This typically, at least on high quality optics, is not visible in the sight, but only from the outside.

Technically, the reflector lens is somewhat like a 2 way mirror, it lets the image of the target pass through the lens, but does not let the red-dot out.

On very low quality red dot scopes, the "red halo" visible in the tube is generally stray "light" from the collimator that has scattered inside the tube. It's a dead-give away of a poor quality scope. The ONLY projected light on the reflector should be the reticle dots.

入門版真鏡, sightmark/ holosun都唔錯
