ORCA®-Flash4.0 LT3 数字 CMOS 相机
C11440-42U40
ORCA-Flash4.0 LT3 是一款用于荧光成像的新型科学 CMOS 相机，是在 2011 年发布的 ORCA-Flash 4.0 的基础上改进而来。
它具有生命科学应用等荧光成像所需的高水平性能，不仅可用于基础研究应用，还可集成到各种类型的设备中。
ORCA是日本滨松光子学株式会社，及其全球子公司（欧洲联盟、日本、英国、美国）注册使用的商标。
特点
- 低读出噪声（标准扫描）：1.5 个电子 (rms)，0.9 个电子（中位数）
- 快速读出（快速滚动，全分辨率）：40 帧/秒
- 大视野：13.312 mm (H)×13.312 mm (V)
- 高分辨率：2048 (H)×2048 (V)
- 高量子效率：82%（峰值 QE）
用途
- 延时成像
- 多维成像
- Ca2+ 成像
- DNA 芯片读取
与 BSI 相机相当或更好的高信噪比
下图比较了第二代 BSI 相机* 的读出噪声分布，表明 ORCA-Flash4.0 LT3 具有更多像素，读出噪声更小。
ORCA-Flash4.0 LT3 具有 1.5 个电子 rms 的低读出噪声，可提供与 BSI 相机相当或更好的高信噪比，尤其是在低光范围内。
这种性能可以在高质量的多维成像中得到证明，例如具有低激发光、低光毒性和光漂白的长时间延迟成像。
* BSI 相机：背照式相机
快速读出
ORCA-Flash4.0 LT3 能够实现 40 帧/秒的读出，甚至比传统的 ORCA-Flash4.0 LT+（30 帧/秒）更快。这对于需要高时间分辨率实时测量的用途非常有用。
大视野
13.312 mm (H) × 13.312 mm (V) 的宽视野支持在单次拍摄中获得更多信息。
这有助于提高 DNA 芯片读取等实验的通量。
PC 建议
随着 ORCA-Flash4.0 LT3 的推出，用户现在能够以每秒 40 帧的速度将 400 万像素的图像流式传输到他们的计算机。通过使用 ORCA-Flash4.0 PC LT3 建议列出的指南，可以满足计算机对高数据率的建议。
