概述:
M24望远镜,是美军的制式镜,和美军的M22制式镜不同,M24镜子很小个头,突出了便携性。小得可以放到外衣口袋里。该产品最初由日本富士公司生产。
我们出售的产品和日本货一模一样,上面有产品型号,和NSN编码,和日镜的差异有两点,一没有在镜体上安装激光防护膜,因为这个产品是由美方承包商采购,可能最终是供应其军队或仆从国军队,所以激光防护膜没有在中国加工和安装以保证订货国的保密及安全问题。二目镜罩是橡胶的,美JUN的则是硬质塑料盖板。在其它方面是一致的。
该产品由中国云南专业作军用望远镜出口的工厂为国外生产,用于恶劣环境下工作使用,镜子内部采用高强度铝合金制造,外包橡胶。这样的好处是由于内部为全金属不会产生碰撞导致的光轴偏移,这个是普通的低价望远镜不可比拟的。
该产品有NSN编号,但是最终是否供应给美国JUN方不清楚,但是该产品按照美JUN标生产并验收。可以达到JUN用品的标准。
望远镜左侧的镜筒内有内置的分划板可以作简易的测距。分划板上面有国际标准的密位线,可以进行概略的测距和角度测量。或者在已经知道距离时,大概测出目标的高宽。
镜体内置有干躁仓,内置干躁剂可以有效的防止发霉起雾。
该产品的镜片品质优秀,加上光路为日本工程师设计,所以镜子的成像清晰锐利。

NORMAL OPERATION
(1) Place neck strap about your neck.
(2) Remove eye-lens cover by first rotating binocular
telescopes inward and then lifting off eye-lens cover.
(3) Unsnap objective covers from front of binocular
and let them hang down from binocular.
(4) Rotate the telescopes of the binocular about the
center hinge until both circular fields of view have
merged into one.
(5) Rotate the pop down eyecups to obtain the
proper diopter settings on the diopter scale .
(6) When sighting through the binocular, hold it in a comfortable and stable position.
(7) Refer to pages 11 and 12 for precautions to be observed when unusual weather or
atmosphere conditions prevail.
(8)Under the special conditions when direct sunlight enters the binocular a portion of
this light will be reflected back producing a glint effect which may be detectable at
positions in the general target field.
USE OF RETICLE
One of the telescopes of the binocular includes a horizontal and vertical scale reticle
graduated in 10 mil increment unit markings (1 unit - 10 mils, 2 units - 20 mils, etc.)
Fire corrections can be made by viewing the impact area and determining angular
corrections by use of the left or right horizontal reticle scale.
USE OF RETICLE
In determining range, if an object fills one 10 mil unit marking on the horizontal retie
scale and is known to be 10 meters wide, the object is 1000 meters away. If the same size
object fills two unit markings (20 mils), it would be 500 meters away. When this formula is
used, the distance will be given in the same units of measurement (feet, meters, etc.) as is
used in estimating the known size of the object. The same formula can be used to determine
range with the vertical reticle scale when the height of an object is known. The use of the
vertical scale is preferred (especially on level terrain), since objects are often viewed obliquely
along the horizontal axis.
