ascamsdk support a variety of APIs, including: Native C/C++,.NET/C#/VB.NET, Python, Java, DirectShow, Twain, LabView, Matlab, etc. Compared with other APIs, Native C/C++ API as a low-level API is characterized by using pure C/C++ development without relying on other runtime libraries. The interface is simple and the control is flexible.
AttosTek provides extensive third-party software support for its UV-Vis cameras and SWIR cameras, facilitating rapid integration and use in various development environments. This includes SDK and demo programs for LabVIEW and MATLAB, as well as DirectShow drivers, Micromanager, and TWAIN SDK drivers. These features enable seamless compatibility with mainstream development environments and third-party software, greatly simplifying the workflow for system integration and secondary development.

Q1 : For the VIS028CU-NC camera, how do you choose between HCG/LCG dual gain depending on the scenario?
HCG High Gain: Reduces readout noise, suitable for weak GFP/RFP fluorescence and low-reflective mineral samples.
LCG Low Gain: Ultra-large full well capacity, resists strong brightfield light and highly reflective wafers, preventing pixel saturation and loss of detail.
Q2 : 2.4 µm vs 2.9 µm pixel sizes: how to choose?
This series offers two pixel size options: 2.4 µm and 2.9 µm:
2.9 µm pixels (VIS028CU-NC): Bigger pixels, more light intake, higher sensitivity (5970 mV/(lux·s)). Great for low-light imaging, fluorescence imaging, and other scenarios where sensitivity is key.
2.4 µm pixels (VIS026CU-NC): Smaller pixels, higher resolution at the same sensor size, perfect for high-resolution detail imaging.
Both cameras cover a spectral range of 400–1000 nm, spanning from visible light to near-infrared.
Q3 : AttosView PC adapter system and microscope-specific features?
AttosView only supports Windows 7/10/11 64-bit systems; core features include 0.02ms~15s exposure adjustment, gain switching, hardware/software binning, ROI cropping, multiple flat/dark field corrections, scale measurement, profile gray curve, TIFF/Raw batch saving, and online firmware upgrades.
