| 41. | Microscope objectives are characterized by two parameters : magnification and numerical aperture.
|
| 42. | Models provide fixed power magnification levels from 1.5?to 6?
|
| 43. | However the designated marksman configuration used a 3.5x magnification scope.
|
| 44. | The amount of magnification depends on the focal length of the eyepiece.
|
| 45. | Excellent quality results up to 4x life-size magnification are possible.
|
| 46. | This would denote 10 times magnification with a 50 mm objective lens.
|
| 47. | A larger magnification leads to a smaller field of view.
|
| 48. | Bundeswehr models are equipped with telescopic sights with 3x magnification.
|
| 49. | Astronomical Barlow lenses are rated for the amount of magnification they induce.
|
| 50. | Amateur telescopes can discern them but require magnification of about 100 times.
