Appearance: 4mm~1200mm+0.0/-0.1mm

Thickness tolerance: ± 0.1mm

Parallelism: 10arc sec~3arc min Surface shape: l/10-l/4

Surface finish: 10/5-80/50

Aperture: 90%

Coating: Optical vacuum coating, zinc sulfide, calcium fluoride, single crystal silicon, barium fluoride, magnesium fluoride, lithium fluoride and other films

Surface defect standard: According to standard MIL-PRF-13830B, use two sets of numbers to represent the size of surface defects

Scratches: Use the surface quality scratch template of MIL-O-13830 as the comparison standard for scratches at all levels

Spicy point:withThe grade of the standard MIL-PRF-13830B is taken as the actual diameter of the allowable defect, and the measurement unit is specified as 1/100mm. If the shape of the dot is irregular, take the maximum length and widthThe average value is taken as the diameter.

The main processing equipment includes optical grinding and polishing machines, optical engraving machines, edge grinding machines, optical vacuum coating machines, and other equipment
