Scanning spectroscopy
Resolution and throughput must be balanced by selecting slit width, focal length and grating rather than treating wavelength range as the only specification.

Engineering reference
Omni-λ3009i is a configurable wavelength-dispersive instrument in the Imaging Monochromator family. The final part number should be released only after the optical, mechanical, electrical and environmental fields below are matched to the intended instrument.
A wavelength-dispersive instrument maps wavelength to position using a grating and a defined focal geometry. Resolution is therefore a system result: focal length, slit width, groove density, diffraction order, detector sampling and aberrations must be evaluated together.
The local price-list record does not provide a complete model specification or datasheet. These fields identify what must be confirmed on the model drawing and quotation without inventing an option-dependent value.
Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Resolution and throughput must be balanced by selecting slit width, focal length and grating rather than treating wavelength range as the only specification.
The dispersion at the focal plane must be sampled by the detector pixel pitch while the active width covers the required instantaneous spectral window.
Technical FAQ
Confirm spectral range, resolution target, grating configuration, optical geometry, detector interface, and scanning and control. These fields are coupled, so the final part number should be checked against the complete instrument rather than selected from the model name alone.
A wavelength-dispersive instrument maps wavelength to position using a grating and a defined focal geometry. Resolution is therefore a system result: focal length, slit width, groove density, diffraction order, detector sampling and aberrations must be evaluated together. Freeze the optical, mechanical and electrical interfaces before releasing the surrounding assembly.
Approve the configuration-specific specification, mechanical drawing, connector or pinout definition, environmental suffix and acceptance-test limits supplied with the quotation. Any field absent from the local record remains a confirmation item, not an assumed capability.

Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
