问1：为什么高灵敏度相机在数字显微镜中更受欢迎

高灵敏度相机之所以被青睐，是因为它们能够探测和捕捉极低光信号，提升数字显微镜中的图像质量和实验灵活性，克服传统显微镜的局限。

问2：什么是可见光相机？

可见光相机是一种成像设备，旨在仅利用电磁波谱中可见的部分（波长约400–700纳米）来捕捉图像或视频，这与人眼可探测的范围相同。

问3：相机USB3.2接口和10GigE接口有什么区别？

相机USB3.2和10GigE接口的核心区别在于设计目标：USB3.2追求在短距离内的高速、简单连接；而10GigE则旨在实现远距离、高带宽的稳定数据传输，并具备强大的组网能力，支持长距离工作。

Q1 : What are the industrial sorting advantages of the SWIR1503B 900–1700nm narrow shortwave spectrum compared to the 400–1700nm models？

Underlying imaging principle: The 900–1700nm wavelength range avoids interference from visible light stray light. Various polymers, sugars, salts, and silicon materials have unique molecular absorption peaks in this range. Materials that look exactly the same under visible light show clear infrared reflection differences, making them easy to distinguish quickly.

Q2 : How to choose among the 5 models in the SWIR1503B series？

The SWIR1503B series comes with a unified configuration high-performance InGaAs sensor. Pixel size, resolution, and cooling are completely the same, with the only differences being in the transmission interface, frame rate, and exposure limits. SWIR1503BU (USB3.0 interface): Frame rate: 724fps at 8/Packet 12bit, 579fps at 14bit; exposure 16μs~5s; no capture card needed. Ideal for desktop lab setups, small offline sample detection, and short-distance laser observation—great for plug-and-play, low-cost solutions. SWIR1503BG (GigE interface): Frame rate: 360fps at 8bit, 180fps at 14bit; exposure 25μs~5s; ethernet cable can transmit up to 100m. Suitable for medium-to-low speed long production line material sorting, remote production line stations, and budget-conscious mass production projects. SWIR1503B10G (10GigE interface): Full-frame 8/14bit both at 724fps; exposure 25μs~5s; supports long-distance high-bandwidth transmission and multi-camera networking. Great for high-speed plastic or powder sorting, and large-area online photovoltaic inspection. SWIR1503BCL1 (CameraLink Full interface): Full-frame 724fps; exposure 16μs~1s; works with CLView capture software. Perfect for traditional research equipment upgrades and standard high-frame-rate spectral experiments. SWIR1503BCL2 (CameraLink Full interface): Maximum full-frame across the series 1000fps; exposure 16μs~1s. Ideal for scenarios needing high frame rates, like pulse laser transient capture and ultra-high-speed material sorting.

Q3 : What application pain points do the three main hardware features—global shutter, hardware ROI, and 512MB cache—solve？

Global Shutter: Eliminates motion blur from high-speed conveyor materials and pulsed laser movements, with an ultra-short 16μs exposure to capture fast-moving objects without any ghosting; exposure ranges from 16μs to 5s to suit both short and long sequence captures. Hardware ROI: Crops out useless background areas in the frame, greatly reducing single capture time and boosting production line speed and efficiency in laser experiments. 512MB Large Buffer: Temporarily stores high-speed image data streams so you won’t miss frames even if your computer isn’t super powerful, ensuring complete continuous sorting and long-timed spectral data.
