FOR IMMEDIATE RELEASE

Photon Grabber for 200 to 800 nm
Efficient Reflective Confocal Objective

Built by McPherson, this reflective confocal objective is for Raman spectroscopy and imaging experiments with varying photon energies. It is designed for use primarily from 200 to 800 nm. Reflective optics are commonly used when experiments operate over a broad spectral range. This design enables the user to introduce the excitation laser in backscattering geometry as well as provide space for polarizers and wave plates.

The high throughput, spectrally agile, 6X reflective objective delivers near diffraction-limited performance in the Visible and UV! The f/1 system uses interferometrically aligned parabolic reflectors with high efficiency broadband coatings for optimal signal collection, excellent throughput and ideal image formation. The Space Optics Research Labs (SORL) produced reflectors feature wave front accuracy of Lambda/10 and are custom polished on ultra-low expansion ceramic, Zerodur™ substrates. Generally, aspheric mirrors provide better image quality and the best collimation in applications with a narrow field of view. They find common use in other objectives, beam expanders, and telescopes.

The objective will be installed at the entrance of a unique McPherson triple monochromator designed for Raman spectroscopy. It will be used for imaging applications in combination with the A504K high-speed camera developed by Basler Vision Technologies AG (Ahrensburg, Germany) in co-operation with the University of Hamburg.

The unique optical system was designed by Dr. M. A. Ruebhausen, of the University of Hamburg Institute of Applied Physics.
