Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
Specification of our optical windows as follow: Round Optical Window,Optical Infrared Window,Optical Square Window,Irregular Window,Optical Flat Window China Star Optics Technology Co.,Ltd. , https://www.realpoooptics.com
When selecting windows, you should consider the following: material,transmission,scattering,wave front distortion,parallelism and resistance to certain environment.
China Star Optics offers all types of windows made from different materials.Special size and materials are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating on Optical Windows.

How imported hot oil cleaning bearings
Soft dry oil or rust-hardened bearings, should be immersed in 100-200 ℃ hot oil, with pliers grip bearing, with a brush to clean the bearings on the oil. Soft dry oil or rust-proof paste is heated to 100-200 ℃ to melt, it is easy to wash out from the bearing loopholes. Occasionally as long as the bearing in the oil several times shaking. Oil will also flow from the loopholes (washing should also be removed when the roller, the pedestal, the inner ring and the outer ring) Put the bearings on the oil immersion 5-10 minutes, one hand pinch the inner ring, the other Hand rotating the outer ring, the bearing dry oil or rust will be lost. Then put the bearings into the cleaner oil, scrub with a gold-plated brush, wash the oil in the balls and holes, and wash in the petrol once and remove it and put it on clean paper. Radial spherical ball bearings and short cylindrical roller bearings wash the ball, pearl frame, the inner ring and the outer ring to wash away.
