ORCA-Fusion デジタルCMOSカメラ
C14440-20UP
微弱光領域（フォトン数が少ない領域）の観察においては、画像のS/N のさらなる改善が最大の課題となっています。QEの向上は大切なアプローチでは有りますが、それ以外にS/Nを改善する方法はないのでしょうか？
浜松ホトニクスでは読み出しノイズの低減に着目し、微弱光領域においても高いS/N が得られるセンサを弊社独自に開発しました。科学計測用カメラのフロントランナーとして、ユニークな視点で新時代を切り開きます。低ノイズ・高画質 第3 世代Gen Ⅲ sCMOS カメラORCA-Fusion の誕生です。
特長
- 低読み出しノイズ: 0.7 electrons rms
- 高画質: DSNU 0.06 electrons / PRNU 0.06 %（7500 electron 時)
- 高速読み出し: 89.1フレーム (2304×2304) / 100 フレーム/ 秒 (2304×2048)
- 広視野: 2304×2304 画素（5.3 M 画素） 対角21.176 mm の広視野センサ
- 高解像度: ピクセルサイズ 6.5 μm
- 紫外や近赤外における 高い量子効率
ライトシート読み出しモード【特許登録済み】
