Classification of measuring projector

1 according to the optical principle divided into positive, negative two, traditional reverse; positive optical path is the two refractive prism in the optical path system based on the original theory to obtain, will cause the attenuation of light path.

2 according to the structure is divided into three:

Desktop, compact, small stroke, generally for the vertical optical path system;

Vertical, an optical axis is perpendicular to the work table;

Horizontal, lens optical axis parallel to the working table;

3 according to the projection screen size classification:

Φ 300m

Φ 350m

Φ 400m

Φ 500m

Φ 600m

Φ 800m

Φ 1000m

Φ 1200m

The 4 functions are divided into three by

Handwheel measurement - micrometer handwheel accuracy is low, did not move quickly

Digital - through the grating ruler displacement signal is converted to digital to analog signal processing results

Data processing by data processing software measurement results, and can export data.

According to the working table stroke divided 5

X*Y=50*50

X*Y=150*50

X*Y=200*100

X*Y=250*150

X*Y=250*200

X*Y=300*200

X*Y=400*300

Horizontal optical path of Y is Z.
