We take pride in the manufacture of high-quality spectroscopic instrumentation. From the optical specialists who grind, polish, and coat our mirrors and fabricate our holographic gratings, to the machinists who manufacture our precision scanning drives and the electronic engineers who design the circuits for our CCD detectors and the computer specialists who write the software, the men and women of Laser Spectra Services are committed to providing the best instrumentation possible.

Resolution figures are generally calculated with 6µm slit widths in the visible and 1200g/mm gratings except for the U1000 where resolution is based on 1800g/mm gratings and the THR1500 where resolution is based on 2400g/mm gratings.
As new instruments and improvements are being made continuously, Laser Spectra reserves the right to change any or all of the above specifications without prior notice.
