Saka optical system

Switzerland imports optical lenses with clear readings. In the shadows of tall buildings, you can easily complete your mission

50 centimetres of vision to ensure that you can work in a narrow space

In line with anthropo-engineering, a good contrast of the lens ensures that you can read with precision in a strong light and reduce visual fatigue。

Simple operation: round bubbles and horizontal scales close to telescopes, easy to read

The direction of the target can easily be found using a crude calibration

(a) images are standing, with an infinite spiral on both sides helping you to quickly and precisely target

Na 728 and na 730 are also equipped with a rough/precipitated focal spiral, with better observations。

Water protection against earthquakes: technology and manufacturing processes make the sealing and seismic-resistant water, dust and sludge of the na 700 series harmless to the instrument

Even if it falls or is subject to other shocks, the instrument can be used directly without having to be re-calibrated or inspected。

The na 700 series captures all the advantages of the same grade scale in order to be durable and cost-effective and to be trusted by users。

Optical systems, which reduce error rates and reduce additional working hours; water-resistant seismic properties, which apply to adverse environments, need not be influenced by weather or other environmental factors。
