It is sold at low prices and is often used as a substitute for the achromatic objective, which is best used in conjunction with a compensating eyepiece. 4. flat field objective (Plan, objective): flat field objective is usually marked with PLAN. The thick lens a half moon increase in the...

An eyepiece lens is constructed with, in order from an entrance side for light to an exit side for light, first, second, third, fourth and fifth lens units of negative, positive, positive, positive and positive refractive powers, respectively. Each of the first, second, third, fourth and ...

As a result, Need to be used with compensating eyepiece. The chromatic aberration objective lens has no restrictions on the light source, and the white light can also get a good effect. Add blue or yellow filters to better effect. Because of all sorts of aberration correction is very ...

to the viewed object, and a folded path which includes an objective lens set (50, 150) an intensifier (60) which converts visible and infrared light to a visible intensified light, and an eyepiece lens set (70, 170) arranged in a loop in a plane perpendicular to the see-through path....
The lens is the most complex and important part of a microscope, working in a wide beam of light (large aperture), but these beams are smaller than the tilt of the optic axis (the field is small). The eyepiece works in a narrow beam of light, but its inclination is large (the ...
the eyepiece needs to be used in conjunction with the compensatingeyepiece. the achromatic objective has no limitation to the light source, andthe white light illumination can also achieve good results. if you add blue oryellow filter, the effect is better. since the correction ofvarious aberratio...
