Scientists convert infrared rays into blue light for sterilization.

　　Optical specifications are used in the whole design and manufacturing process of components or systems to describe the extent to which they meet specific performance requirements.They are useful for two reasons:

　　1)Firstly,they specify the acceptable limits of key parameters controlling the performance of the system;

　　2)Second,they specify the amount of resources(i.e.time and cost)that manufacturing should spend.

　　In order to understand optical specifications,it is important to first review their meaning.

　　Vy optoelectronics Co.,Ltd.provides a brief introduction to the optical specifications of the lens,hoping to help you better understand the optical lens.

　　To simplify the growing number,consider the most common manufacturing,surface,and material specifications for lenses,mirrors,and windows.Filters,polarizers,prisms,beam splitters and optical fibers also have many of the same optical specifications,so understanding the most common specifications will provide a good basis for understanding almost all optical lenses.

　　Manufacturing specification

　　Diameter tolerance

　　The diameter tolerance of circular optical elements provides the applicable diameter value variation.Although the diameter tolerance has no effect on the overall optical performance of the optical element itself,if the optical aspect is to be installed in any type of support,the very important mechanical tolerance should be considered.For example,if the diameter of the optical lens deviates from its nominal value,the mechanical axis may also deviate from the optical axis in the mounting part,resulting in eccentricity(Fig.1).Typical manufacturing tolerances for diameters are+0.00/-0.10 mm(typical mass),+0.00/-0.050 mm(precision mass)and+0.000/-0.010 mm(high mass).

　　Wuhan teguang Technology Co.,Ltd.can produce lenses with a diameter of 0.5mm to 500mm,with a tolerance of+/-0.01mm or+/-0.001mm.
