System Configuration and Parameters

Updated SWIR modular microscopy parameters for semiconductor, materials science, and industrial inspection across the 900-1700 nm waveband.

SWIR Modular Microscopy Technical Features

The BSM Series combines SWIR optical compatibility, silicon penetration capability, modular illumination, high-sensitivity imaging, and precision mechanics to deliver practical infrared microscopy on conventional microscope platforms.

Optical Compatibility

SWIR microscopy in the BSM Series works with standard glass lens systems, avoiding the reflective optics often required in MWIR and LWIR imaging and simplifying integration into conventional microscope platforms.

Silicon Penetration Capability

Because SWIR photon energy is below silicon's bandgap, the BSM platform can inspect internal defects in silicon-based materials such as hidden cracks in wafers, chips, and electronic interconnect structures.

Illumination and Imaging Modules

The system combines coaxial Kohler illumination, dedicated SWIR wavelengths, and high-sensitivity SWIR cameras with refined optical paths and large numerical aperture objectives for micron-level inspection.

Mechanical Module Stability

Precision CNC machining and anti-vibration structural design support stable observation and repeatable imaging in automated, continuous, or high-throughput inspection workflows.

Enhanced Material Contrast

SWIR wavelengths reveal features that are obscured in visible-light imaging, improving contrast for ceramics, composites, semiconductor structures, and other subsurface targets.
