Perfect for precise measurements of number of optical systems. Mounted in 40mm diameter metal mount. Graticule Diameter is 27mm. Patterns made with low reflection hard chrome deposition imparts high contrast for easy readability. The following patterns are available:
Angle scales 0° to 80° in 5° divisions and 80° to 90° in 1° divisions. Radius scale 0.1 to 1mm in 0.1mm and 1-10mm in 0.5mm radii. Angle scale 29°, 55°, 60°and 118°. Ten circles on left 0.1 to 1.0 in 0.1mm divisions and ten circles on right from 0.005″ to 1/64″ dia.
Three linear scales:
- 10-0-10mm with 0 to 1mm in 0.05mm divisions, 1mm to 5mm in 0.1mm divisions and 5mm to 10mm in 0.5mm divisions
- 0 to 0.5″ in 0.005″ divisions
- 0 to 1/8″ in 1/64″ divisions
Graph of 10mm x 10mm divided into 0.5mm squares. Ten circles form 0.1mm to 1mm in 0.1mm increments and three circles of 1.5mm, 2mm and 2.5mm dia. Horizontal scale 10mm in 0.1mm divisions.
Protractor scale 0° to 180° numbered every 10°, divided each degree. Radius scales 0 to 10mm in 0.5mm divisions.
Angle scales 0° to 90° in 1° divisions. Radius scale 0.5 to 10mm radii in increments of 0.5mm. Two circles 1.5mm and 3mm dia. Seven circles from 0 to 0.7mm in step of 0.1mm. Linear scale 20mm with 0.1mm divisions. 0.3″ X 0.4″ grid in 0.025″.
