Description
Model 2010/M Specifications
Index Accuracy: ±0.0005 (worst case), limited mainly by uncertainties in prism angle and refractive index. With a high-resolution rotary table and simple calibration per prism, accuracy improves to ±0.0001–0.0002. Calibration standards (e.g., NIST, fused silica) are available.
Index Resolution: ±0.0003 (worst case). Improves to ±0.00005 using a high-resolution table (no-cost option).
Thickness Accuracy: ±(0.5% + 5 nm)
Thickness Resolution: ±0.3%
Refractive Index Measuring Range: Up to 2.65 with standard prisms. Specialized prisms available for materials up to 3.35 (consult Metricon).
Film Types & Thickness Ranges Measurable: Can measure virtually any film that is not metallic or highly absorbing at the operating wavelength. Dual-layer films measurable if the top film has higher refractive index. Minimum measurable thickness depends on the film/substrate index.
Measurement Area: Contact area ~8 mm²; actual measurement area ~1 mm diameter.
Typical Measurement Time:
10–25 seconds with standard table
20–75 seconds with high-resolution table
Operating Wavelengths:
Standard: 633 nm
Optional visible: 405, 450, 473, 532, 594 nm (for thinner films)
Optional near-IR: 830, 980, 1064, 1310, 1550 nm (for fiber/integrated optics)
Note: Optional sources increase CDRH laser safety class to IIIa or IIIb
Laser Diodes Installed: 405 nm, 521 nm, 636 nm
Prism Code: 999.5
