XOA-1200 Optical Spectrum Analyzer

Visible-to-Near-Infrared Optical Spectrum Analysis

The XOA-1200 Optical Spectrum Analyzer measures optical power as a function of wavelength from 350 to 1200 nm. Its coverage supports short-wavelength lasers, LEDs, passive optical components, biomedical optics, material processing, and consumer or healthcare photonics.

Published performance is interval- and setting-dependent. The 0.01 nm resolution setting is available only from 400 to 470 nm. Across the full wavelength range, selectable resolution settings begin at 0.02 nm and extend to 10 nm.

Wavelength, Resolution, and Sampling

Parameter	Published performance
Wavelength range	350 to 1200 nm
Scan span	0.5 to 850 nm including full range; 0 nm
Wavelength resolution	0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, and 10 nm over the full range
Band-limited finest resolution	0.01 nm from 400 to 470 nm
Wavelength accuracy	±0.05 nm at 633 nm; ±0.2 nm from 400 to 1100 nm after calibration with a 633 nm He-Ne laser
Minimum sampling resolution	0.001 nm
Sample points	101 to 50,001 plus AUTO

The full wavelength range is broader than the interval covered by the published ±0.2 nm accuracy figure. No additional accuracy value is inferred for 350 to 400 nm or 1100 to 1200 nm.

Sensitivity and Input Limits

Wavelength interval	Published sensitivity in HIGH3	Published maximum safe input
350 to 400 nm	Not specified	Not specified
400 to 500 nm	-60 dBm	+10 dBm from 400 to 550 nm
500 to 1000 nm	-80 dBm	+10 dBm to 550 nm, then +20 dBm from 550 nm
1000 to 1100 nm	-60 dBm	+20 dBm
1100 to 1200 nm	Not specified	Not specified

Sensitivity values require resolution of at least 0.2 nm, 10 averages, and HIGH3. The safe-input values are total input-power limits. Unspecified edge intervals are not treated as zero and are not extrapolated from adjacent bands.

Power and Dynamic-Range Conditions

• Power accuracy: ±1.0 dB at 850 nm and -20 dBm input, with resolution of at least 0.2 nm, MID or HIGH1 to HIGH3, and the stated single-mode fiber conditions.
• Power linearity: ±0.2 dB from -40 to 0 dBm input in HIGH1 to HIGH3.
• Dynamic range: 60 dB at 633 nm, 0.02 nm resolution, and ±0.5 nm from the spectral peak.

These are conditioned values, not full-range guarantees.

Optical Input and Measurement Workflow

The FC optical input supports single-mode fiber, GI 50/125 µm, GI 62.5/125 µm, and large-core fiber up to 800 µm. The built-in alignment source supports optical-axis adjustment. Five sensitivity modes trade scan time against low-level performance: NORMAL 1 s, MID 2 s, HIGH1 5 s, HIGH2 20 s, and HIGH3 75 s.

The 12.1-inch touch interface provides multi-application spectrum analysis and visible colour analysis for source and component development, validation, and repeated measurement.

Scope to Confirm During Quotation

The published XOA-1200 specifications do not state mechanical dimensions, mass, mains-power requirements, environmental limits, warranty terms, or detailed remote-control interfaces. Include those requirements, the desired optical interface, calibration documentation, and the target wavelength/power range in the quote request.
