Overview:
Since high-quality artificial blue/ruby crystal materials have good light transmittance in the 0.20~5.50μm band, and the infrared transmittance hardly changes with temperature, optical elements and infrared-transmitting optical windows made of high-quality artificial sapphire are used , has been fully used in military night vision infrared equipment, low-temperature laboratory observation ports, high-precision instruments and meters for navigation, aerospace, and aviation.
Overview:
1. Outer circle diameter D: Ø 0.60~ Ø 20.00mm, the minimum outer circle tolerance can reach 0.005mm;
2. Thickness H: 0.20~8.00mm, the minimum thickness tolerance is 0.01mm, the parallelism error of both end surfaces is not greater than 0.02mm, the surface roughness reaches Rz0.1 (mirror surface), and the verticality error of both end surfaces relative to the axis of the inner hole is not more than 0.02mm. greater than 1°;
3. Inner hole diameter d: Ø 0.13~ Ø 3.00mm, the minimum hole diameter tolerance can be controlled at 0.004mm, the roundness tolerance and cylindricity tolerance of the inner hole are not greater than the bearing inner hole diameter tolerance;
4. Oil groove: depth h=1/3H, the minimum tolerance can be controlled at 0.04mm, the minimum curvature radius SR can be controlled at 0.30, and the surface roughness can reach Rz0.2.
