Strong and durable

All metal construction, durable steady for a long-term use.

For terrestrial or astronomical use, the mirror produces a face-up, non-inverted image with correct daytime orientation

Why are reflecting telescopes not suitable for use with diagonal mirrors?

Generally, the optical structure of the reflecting telescope does not reserve the optical path of the diagonal mirror, and after adding it; due to the structure of the reflecting telescope, it is not convenient to use with the diagonal mirror.

What are the benefits of high reflectivity for diagonal mirrors?

The higher the reflectivity of the diagonal mirror, the greater the light transmittance and the clearer the image

What is the difference between a prism diagonal mirror and a reflective diagonal mirror?

The prism-type diagonal mirror has less scattered light. It is more suitable for a long focal ratio telescope. The reflective diagonal mirror has chromatic aberration Smaller, but has some stray light, better suited for short focal ratio telescopes

In what scenarios can a diagonal mirror be used?

It can be used for astronomical scene observation when used with an astronomical telescope; it can be used for ground observation when used with a spotting scope
