Fizeau Interferometer for Flat Surface Measurement 4-Megapixel Imaging and 3 Optional Sources
Vertical Mounted S300|HR
The S300|HR can be mounted vertically or horizontally. Pictured here is the convenient vertical configuration for measuring flat components or blocks of parts such as prisms or cubes.
- Image Resolution: 230 µm (4.2 l/mm)
- Image Distortion: <0.06%
- Fringe Resolution: >500 fr/aperture
- Retrace Error 3 @ 200 fringes: < λ/15 4
- RMS Simple Repeatability 1: <0.6 nm RMS 2σ
- RMS Wavefront Repeatability 2: <0.6 nm RMS 2σ
- Measurable Part Reflectivity: 0.5% to 100% Specify
1 RMS Simple Repeatability Test: The RMS for 36 sequential measurements with each measurement the average of 16 measurements each of a short <2 mm plano cavity
2 RMS Wavefront Repeatability Test: Measure 36 sequential Measurements (M1, M2,...M30) each consisting of 16 averages. Then average all 36 measurements create a synthetic reference, "Ref", RMS wavefront repeatability equals the 2X the standard deviation of all 30 Ref - Mn results.
3 Retrace Error is defined as the PV residual error between a nulled measurement (the reference), subtracted from a measurement with 500 fringes of tilt, and expres sed by the first 36 Zernike polynomials
4 λ/20 optionally available
