HD-SWIR Digital Microscope / Tabletop or industrial design

The HD-SWIR Digital Microscope is designed to “see” beyond what a standard optical microscope can image.  Combining SWIR coated optics, SWIR illumination and a high resolution SWIR camera, the HD-SWIR microscope is a cost effective solution can image microscopic samples in the visible and the shortwave infrared region, thus covering a spectral range from 400 to 1700 nm. A variety of filters allows imaging in the SWIR only 0r to focus on spectral band or wavelength of interest.

Microscopy beyond the visible

The HD-SWIR Digital Microscope is designed to “see” beyond what a standard optical microscope can image.  Combining SWIR coated optics, a SWIR illumination and a high resolution SWIR InGaAs camera with 5 µm pixel pitch, the HD-SWIR microscope is a cost effective and modular solution that can image microscopic samples in the visible and the shortwave infrared region (400 to 1700 nm). A variety of filter options allow imaging both visible and SWIR (400 – 1700 nm), SWIR only (900 – 1700 nm) or to focus on a spectral band or specific wavelength of interest.

Some materials are transparent in the SWIR while being opaque in the visible spectrum. For example, silicon is opaque under normal light but is transparent in the SWIR wavelengths. Therefore, .the interiors of silicon based devices can be inspected with enhanced contrast without having to disassemble them.

Cost-effective, high-resolution and modular

Smallest InGaAs pixel pitch of 5 µm for high resolution microscopy

Boasting 1280 x 1024 pixels , a 5 µm pixel pitch and a high QE from 400 to 1700 nm, the HD-SWIR microscope outputs high-resolution images with unparalleled  details. The thermoelectric  cooling ensures high image quality even at longer exposure times.

Other camera models are available depending on the application (deep cooled or high-speed)  See our  SWIR camera page here.

The HD-SWIR Digital Microscope is designed to “see” beyond what a standard optical microscope can image.  Combining SWIR coated optics, SWIR illumination and a high resolution SWIR camera, the HD-SWIR microscope makes SWIR microscopy a cost effective solution that can image microscopic samples in the visible and the shortwave infrared region, thus covering a spectral range from 400 to 1700 nm. A variety of filters allows imaging in the SWIR only 0r to focus on spectral band or wavelength of interest.

HD-SWIR Digital Microscope main components

  • A high-resolution SWIR InGaAs camera with 1280 x 1024 pixels (or 656 x 512), 5 µm pixel pitch, and high QE from 400 to 1700 nm. The 5 micron pixel pitch is the smallest in the industry, thus enables resolutions never reached before for SWIR wavelengths. A visualization software and complete SDK allow for easy use in the lab (tabletop version) or in production environment (industrial version). Other camera models (deep cooled or high-speed) are available upon request (see SWIR camera page here). The Goldeye G-130 uses the IMX990 and enables high resolution SWIR microscopy
  • SWIR optimized optics: all optics, included the microscope objective, are coated for optimal transmission in the SWIR (>900 nm). Magnification can easily be adjusted manually or electronically, thus allowing to quickly adapt the field of view.
  • SWIR illumination: a halogen lamp (broad spectrum covering visible and SWIR) can be used with a coaxial port, thus allowing illumination of the sample directly through the optics. Optionally, transmission-mode imaging is possible using a SWIR LED backlight with single wavelength emission spectrum.

Tabletop and industrial designs

    • the tabletop design includes a stand with focus adjustment (coarse + fine) and an optional X/Y translation mount for holding the sample
    • the industrial design allows easy integration thanks to a clamp mount. The long working distance of the objective (>30 mm) facilitates sample manipulation while maintaining a safe distance.Goldeye G/CL 130 filter mount
