BUC5IC-400BM TE-Cooling M52/C-Mount USB3.0 CMOS Microscope Camera (GSENSE2020BSI Sensor, 4.2MP)
Introduction
With the two-stage peltier cooling sensor chip to -40°C below ambient temperature. This will greatly increase the signal to noise ratio and decrease the image noise. Smart structure is designed to assure the heat radiation efficiency and avoid the moisture problem. Electric fan is used to increase the heat radiation speed.
BUC5IC series comes with advanced video & image processing application ImageView; Providing Windows/Linux/ OSX multiple platform SDK; Native C/C++, C#/VB.NET, DirectShow, Twain Control API;
The BUC5IC series can be widely used in low light environment and microscope fluorescence image capture and analysis, as well as the astronomy deep sky application.
