Scale reticle for measuring magnifiers, No.4

Scale reticles for measuring magnifiers, 7x (26mm), 10x (35mm) and 15x (26mm). 

Specifications of reticle No.4:

• Degrees: 0-90° (one 10° area marked in 1° intervals)
• Scale: ± 0 to 10mm (0.1mm divisions)
• Squares: 5 x 10mm (0.1mm divisions)
• Circles: 0.1 to 1.0mm diameter (0.1mm divisions)
• Radius: 0-90° (0.1 and 0.5mm divisions)

Note: All reticles with the correct diameter can be fitted to magnifiers for special sizing purposes but high-power magnifiers have a limited field-of-view. The 30x magnifier (which uses a 26mm reticle) 'sees' only 7mm and therefore these special reticules would rarely be of use.

Divisions of straight scales:

• No. 1 - Length 20mm, divisions 0.1mm
• No. 2 - Length 1mm, divisions 0.05mm. Length 20mm, divisions 0.1mm
• No. 8 - Length 20mm, divisions 0.1mm
