Multi-element Lenses
An economical achromat for general use, suitable for an optical system that does not require high surface quality imaging, such as a microscope or telescope objective.
By combining two lenses with different wavelength dispersion and refractive index, the resulting component provides lower spherical aberration and chromatic aberration than a single spherical lens.
A cylindrical achromat is a single component made by joining two cylindrical surface lenses with different refractive indices.
These reflective microscope objectives are optimized for chromatic aberration over a bandwidth of 350 nm to 7 µm.
With their long acting infinity correction function, these objectives can be used for a laser system and coaxial observation.
With these objectives, the user can focus a visible laser or microscopic observation of objects from a distance.
With its long working distance and field curvature correction, a natural observation image is achieved to the periphery of the field of view.
With its long working infinity correction function, this objective can be used for a laser system and coaxial observation. It is also used for near UV light observation.
These are infinity corrected objectives with high NA for laser processing.

The beam analysis camera WinCamD-IR-BB with integrated microbolometer array enables analyzes on long-wave lasers in the range of 2 μm to 16 μm.
This Laser Beam Profiler from DataRay is equipped with a CQD sensor and offers a spectral response in the SWIR range of 400 - 1700 nm with resolutions up to 1920 x 1080 pixel.
DataRay's ILM system is used for beam profile monitoring of high power lasers consisting of an attenuator for high powers, an imaging lens system and a camera system. The measurement of very small laser beams with diameters of less than micrometers is possible despite often high laser powers.
A main feature of the WinCamD is the optional M2 Stage. Thus, it can be easily extended to a complete M2 measurement system.
