DRAWING AND QUOTATION CHECKLIST
1. Geometry: diameter or length x width, thickness, clear aperture.
2. Dimensions: tolerances, surface quality, flatness, wavefront and test wavelength.
3. Mounting: parallelism or wedge, edge treatment, seal and unsupported area.
4. Optical band: wavelength range, coating, incidence angle and polarization.
5. Laser conditions: CW power or pulse energy, pulse width, repetition rate, beam size.
6. Environment: media, pressure differential, temperature and mount constraints.
7. Acceptance: inspection reports, sampling plan, spectral testing requirements.
8. Commercial: quantity, destination, price, verified availability and lead time.

NOTES
Material properties are reference values. No numeric size range, machining tolerance,
coating reflectance, damage threshold, stock level, lead time or price is guaranteed.
Request order-specific confirmation. A flat window is not a focusing lens.
Use clean gloves and edge handling. Avoid abrasive contact and uncontrolled machining.
Request SDS and coating-specific cleaning advice. Isolate damaged optics.
