The 3580 OES system provides the dual capability of simultaneous and sequential analysis in a single, integrated package, Combining the high-throughput, parallelchannel power of the 3560 with the versatility of the 3520's sequential spectrometer technology, the 3580 will accommodate any of four excitation stands and offers the benefits of both the 3520 and 3560 in one comprehensive system. The ARL 3580 OES -the ultimate optical emission instrument.

| Optics
| entrance slit width: 20 µm; exit slit width: 50 µm; 7
filters for order separation and stray light reduction
| | Wavelength range | 165-800 nm
| Wavelength drive
| Monochromator: fixed optical mounting; exit slits are equally spaced (every 2 mm) on steel masks in focal plane; 2 moveable photomultipliers (10 stage-l U.V. and 1 for visible range) and moveable entrance slit allow random wavelength access. Polychromator: computer controlled stepper-motor driven primary slit allow random wavelength access for peak scanning and off-peak background correction | | Resolution | Reciprocal linear dispersion is 0.93 nm/mm in 1st order, 0.46 nm/ mm in 2nd order, 0.31 nm/mm in 3rd order, and 0.23 nm in 4th order.
Resolution with 20 µm primary and 50 µm secondary slits is 46 pm in 1st order, 23 pm in 2nd order, 16 pm in 3rd order, and 12 pm in 4th order (all FWHM). | | Detector | Polychromator: up to 59 channels, each optical channel consists of a secondory slit, 45 deg. mirror, filter (optional), and photomultiplier tube | Detection mode
