magnification power to make sth appear bigger He paused for a moment , increasing the magnification on the microscope . Binoculars are classified according to their magnifications and the diameters of their main object-glasses . high low Use as high a magnification as possible , though it is true that the real complexity of the nebula cannot be properly seen without a telescope . With × 20 I have found that near maximum its colour is very clear , and it is detectable with lower magnifications . of number of degrees Any magnification of over × 7 will start to resolve it , and with × 20 many stars in it can be seen . In short : if you are going to have only one pair of binoculars , choose a magnification of between × 7 and × 10 , with an aperture of between 40 and 60 millimetres . under magnificationPigment analysis also involves studying a cross-section under magnification , and optical examination can be backed-up by using LMA , EDX etc . act or process of making sth appear bigger For such pupils , the application of reduction can be more useful than magnification . It has the opposite effect from magnification, which reduces the field of vision Difficult to achieve magnification , ie to enlarge newsprint ( but this can be done on the overhead projector ) . of However , as with the magnification of print by lenses or low vision aids , enlarged print has the disadvantage of reducing the number of words or even letters that can be glimpsed at one time , and therefore may reduce speed and fluency in reading .
