ポータブル皮膚測色計 SkinColorCatch
主な特徴
皮膚のエリスマや色素沈着の指標となるエリスマ、メラニンインデックスを測定・表示します。従来機では互いのインデックスが相互に影響してしまい、例えばエリスマの値がメラニンに影響を受けるような事例が見られました。「ポータブル皮膚測色計SkinColorCatch」ではそれらの問題が解消されており、それに加えRGB、 CIE L*a*b* 、L*c*h* 、ITA等の測色機能によるスキントーンの分類も可能です。
■エリスマ、メラニンを高い感度で測定
■相互に感受性のないインデックスを実現
■RGB、 CIE L*a*b* 、L*c*h* 、ITAも計測
■校正チェックツール同梱
■ポータブルでハンドヘルド
■測定、データ転送はスイッチを押すだけの簡単操作
■ケーブルレスで顔等の小さな面も簡単に測定が可能
■姉妹機と連携してマルチシステムを構築
■ワイヤレスをオフにして本体表示でスタンドアローンの使用も可能
■バッテリー駆動
1)化粧品産業用研究機器 2)国内技適済みワイヤレスモデム内蔵
アプリケーション
- エリスマ関連のアレルギー、荒れの観察
- UV照射によるエリスマ、色素沈着の評価
- 美白有効性評価の指標
測定の仕組み
ポータブル皮膚測色計 SkinColorCatch:測定原理
白色LEDを測定チャンバー内に円形に配置することで日の光を再現しています。先端部を軽く皮膚に押し付けることでLEDが45度から照射され皮膚のテカリを最小限にしながら測定を開始します。皮膚から反射された光は内蔵のRGBセンサーで感知されL*a*b*値等が計算されます。測定は周囲の光に影響を受けにくく、また開口部は皮膚に押し付けた際に皮膚が白くなることにより受ける影響を最低限にする工夫がされています。
