Photon Engineering 非常高興公開最新版本的 FRED , 我們的高階光學仿真軟體 FRED 7.50.0 版本更新許多功能。包含了 多核心執行效能提升、增加 volume scatter 及 coatings 的 Script 指令、簡化 CAD 匯入的物件數量、新增光源檔類型及新光原始檔案匯入介面等等。還有許多配合新功能的 Script 指令被加入到這次的版本更新之中；使用者可以在新版本 Release Notes 中找到新功能說明。

新版本 FRED 在匯入 CAD 檔案 (IGES 或 STEP) 後，預設為一個新簡化的形式樹狀列，自動隱藏被用來使用於孔徑與削切的線段與表面，使用者可以得到更精簡幾何結構樹狀列。

FRED 在建立光源處，新增一個可以匯入二進位檔案 ASCII 光源檔案，並且可以自由設定匯入的光線數量。

現在使用 FRED 的 開啟舊檔的對話方塊 ( 從 File=>Open ，或快捷鍵 < Ctrl+O > ) ，它的預設檔案讀取格式，為 FRED 視窗介面的 .frd 及 Script 介面的 .frs 檔案類型；在此之前預設檔案讀取格式只有讀取 .frd 的設定。

新版本 FRED 對於多核心系統的運算效能有著顯著的提升，包含了追跡光線歷史軌跡資訊及光線路徑記錄時不再局限于單核心運算；另外照度運算、能量密度及 Scalar Field 等分析功能，皆可使用高核心數進行運算 ( Standard 版本 FRED 可支持雙核心運算及 最高 8 核心運算的 FRED Turbo 版本 ) 。

FRED 7.50.0 版本新增了 42 個 Scripts 指令。這些指令部分支援新功能，其他的部分則為應使用者要求所新增如下所列：
