MICROSCOPY with visible light in combination with X-RAY AND ELECTRON BEAMS

On-axis sample viewing microscopes OM-1 and OM-2

Visualisation of samples in high resolution

Experiments with X-rays and electrons tremendously benefit from an independent sample observation with visible light. Our compact on-axis
sample viewing microscopes allow visualization of the samples at high resolution and coaxial to the incident X-ray or electron beam.
For this the microscope objectives and a deflecting mirror are equipped with drill holes in their optical axis, allowing the beam to pass through.
Optical ports of our OM-1 and OM-2 allow for through-the-lens illumination and laser excitation of the samples. In contrast to our basic version
OM-1, the OM-2 is equipped with a 5-axis positioning system and also available as ultra-high vacuum (UHV) version.

Configurable optics

  • Our OM-1 and OM-2 can be equipped with different microscope objectives
    Objectives with 5x, 10x, 20x and 50x magnification
  • IR and NUV (near UV) objectives available
  • Depending on the microscope objective working distances vary between
    8 mm and 25 mm with numerical apertures (NA) ranging from 0.05 to 0.5
  • The drill hole diameter can be specified by the customer.
  • For minimal scattering background a thin-walled tantalum capillary can be inserted into the optics.

Integrated laser excitation and sample illumination

  • Configurable optical port for laser excitation of the sample for pump-probe experiments with excitation wavelengths between 350 nm and 1500 nm.
  • Flexible optical configurations allow for different excitation schemes with laser spot sizes between 2 µm and 200 µm on the sample
  • Interchangeable dichroic beam splitters allow for efficient separation of pump and observation light
  • Optional through-the-lens LED sample illumination of the entire field of view with monochromatic visible light, white light or infrared light (850 nm – 1000 nm).

Flexible mounting options and operating environments

  • The OM-1 is the compact version for space-constrained environments and does not include any positioning systems. It can be mounted in different orientations on existing or customer provided positioning systems.
  • Our OM-2 is our high-end on-axis viewing system and includes a compact five-axes motorized positioning system for easy and precise alignment along the incident beam.
  • The OM-2 is also available in a ultra-high vacuum version (UHV).
