CM-150 Screen Centering Microscope for Lab Centration Inspection

CM-150 Screen Centering Microscope is a transmission-type centering tester from Nanjing AMADA Instrument Co., Ltd. designed for lens centration error inspection, lens cementing, and lens-barrel assembly in optical manufacturing. It features a 9-inch LCD display, LED illumination, electronic reticle, and fixed 15″ per division reticle graduation independent of magnification. The system supports lenses with effective outer diameter Ø3 mm to Ø150 mm and focal length ±5 mm or more.

  • Fixed 15″ per division reticle graduation remains unchanged across different lenses, ensuring consistent measurement reference
  • 9-inch LCD display reduces visual fatigue during prolonged inspection tasks
  • LED illumination provides long life and energy efficiency with stable output
  • Electronic reticle enables operation in darkrooms without ambient light interference
  • Single-focus setup required per lens type—only the first lens needs focusing, speeding up workflow

Use guide

  • Select CM-150 for inspection of lenses with effective outer diameter Ø3 mm to Ø150 mm and focal length ±5 mm or more
  • Use only the first lens of each type to set focus—subsequent lenses in the same type do not require refocusing
  • Enable electronic reticle for darkroom operation; ensure power supply is connected via AC adapter
  • Attach optional three-jaw chuck when securing irregular or small lenses

FAQ

What is the reticle graduation and does it change with magnification?
Fixed at 15 seconds per division, independent of magnification or lens type.
Can I use this microscope in a darkroom?
Yes. The electronic reticle allows operation in darkrooms without ambient light.
What is the measuring range for lens diameter and focal length?
Effective outer diameter: Ø3 mm to Ø150 mm; focal length: ±5 mm or more.
Do I need to refocus for every lens?
No. Only the first lens of each type needs focusing; subsequent lenses in the same type can be inspected without refocusing.
What power supply is required?
AC adapter with input AC 100–240 V, 50/60 Hz; output DC 12 V, 1 A.
