Scale reticles for measuring magnifiers, No.11

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

Specifications of reticle No.11:

• Screw Threads: 50, 18, 20, 8, 16, 32, 24, 28, 14 per inch.

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
