Optics Handling

Lab 04: Cleaning

Clean mounted and unmounted optical surfaces using the safest, simplest method. Document hardware, solvents, signoffs, and before/after evidence.

Hardware Checklist

Nitrile/latex gloves Fume hood flowbench Fiber-free synthetic wipes Fine brush Distilled water Inert gas Isopropanol or methanol FirstContact Dawn dish soap and water

Procedure Signoff

Verify PPE and work area Record hardware manufacturer/model/serial Clean at least two unmounted optics / four surfaces Use distilled water first, then other solvents safely Clean at least one mounted optical surface Upload before/after photos or micrographs Write student analysis

Optical Inspection

Lab 09: Scratch-Dig

Inspect optical and non-optical surfaces for scratches, digs, sleeks, coating flaws, cleanliness issues, and permanent surface features.

Hardware Checklist

Inspection hood Black matte paint or black felt 40-watt optical source High-intensity LED or fiber source Clean flat common materials Optical materials Scratch-dig reference set Microscope with calibrated reticle/camera

Procedure Signoff

Set up inspection hood Clean optics before inspection Inspect one non-optical and two optical surfaces Compare flaws to scratch-dig standards Draw a map of surface imperfections Classify scratch-dig visibility class Explain how permanent features were separated from contamination

Interactive Defect Map

Mechanical Profiler

Lab 10: Surface Texture

Build a mechanical profiler concept that transfers stylus deflection into laser spot motion and compare rough and optically smooth samples.

Hardware Checklist

Optical breadboard Diode laser Mirror Cantilevered arm and stylus probe Linear stage Position-sensitive detector or screen Rough and smooth material samples

Procedure Signoff

Confine and document the beam path Configure probe contact and flexure Translate sample or probe over measured range Verify deflection stays within detector range Measure a rough surface Repeat with optically smooth surface Document calibration, range, and resolution

Optical Profiler

Lab 11: Surface Roughness via Optical Profiler

Use a 4D NanoCam or Zygo ZeGage optical profiler to measure RMS surface roughness, document instrument settings, and compare results to specification.

Hardware Checklist

4D NanoCam + 4SightFocus 5x Linnik objective Calibrated reference flat Zygo ZeGage + Mx software 10x Mirau objective Flat polished optics Curved polished optics Ground optical surfaces

Procedure Signoff

Create a user data directory Verify objective and instrument settings Set reflectivity, resolution, unwrapping, shape removal, and statistics Focus sample edge and adjust exposure Use autofocus and tilt to reduce fringes Measure at least five regions Calculate average RMS and compare to spec Upload interferograms/screenshots

RMS Average Calculator

Enter comma-separated nm RMS values. Example: 2.8, 3.1, 2.9, 3.0, 2.7
