Integration and compatibility
Use these checks to connect Omni-λ5005i to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Spectral range and resolution
- Resolution (PMT): 0.05 nm · Resolution (CCD, 26 µm): 0.11 nm
- Resolution is a budget, not a property: focal length, groove density, slit width, diffraction order and detector pixel pitch all enter it, and the quoted figure applies only at the wavelength and slit width it was measured at.
- Grating and dispersion
- Focal length: 500 mm · Dispersion: 1.49 nm/mm
- Confirm the installed gratings, their blaze wavelength and the turret population. A shared chassis name does not imply the same grating set, and blaze position decides efficiency far more than groove density alone.
- Slits and optical ports
- Aperture ratio: f/6.5 · Slit: Width 0.01–3 mm, motorised or manual; height 2, 4 or 14 mm selectable
- Match the input f-number to the instrument, not the other way round. Overfilling the acceptance cone adds stray light and no signal; underfilling wastes throughput you have already paid for in aperture.
- Detector interface
- Focal plane size: 30 (w) × 14 (h) mm · Interface: USB 2.0 and RS232
- Match the detector active height and pixel pitch to the focal-plane dispersion before committing to a mount, then confirm wavelength calibration, scan repeatability and trigger behaviour for the acquisition you intend.
