FMA 23.2mm Eyepiece to Fixed Microscope Eyepiece Adapter

FMA 23.2mm Eyepiece to C-mount Fixed Microscope Eyepiece Adapter series connects 23.2mm diameter eyepieces to C-mount microscope cameras. Available in four magnification options (0.37X, 0.50X, 0.75X, 1.00X) for compatibility with sensors from 1/4" to 1" in size. Designed for fixed mounting on microscopes with 18mm field of view eyepieces.

  • Direct adapter from 23.2mm eyepiece to C-mount camera with no optical shift
  • Four magnification options to match sensor size and field coverage
  • Fixed mounting design ensures stable alignment during imaging
  • Supports cameras with sensors from 1/4" to 1" in size
  • Prevents vignetting by matching adapter size to sensor dimensions

Use guide

  • Identify the sensor size of your C-mount camera
  • Match the sensor size to the correct FMA model (FMA037 to FMA100)
  • Ensure the microscope uses an 18mm field of view eyepiece
  • Install the adapter directly onto the eyepiece and connect the camera to the C-mount

FAQ

What camera sensors are compatible with each model?
FMA037: 1/4"–1/3"; FMA050: 1/2"–2/3"; FMA075: 1/1.8"–1"; FMA100: 1"
Can I use this adapter with a 20mm field eyepiece?
No. This adapter is designed for 18mm field of view eyepieces only.
Is the adapter adjustable?
No. It is a fixed mounting adapter with no focus or tilt adjustment.
Do I need to adjust the microscope focus after attaching the camera?
No. The adapter does not alter the optical path; focus remains unchanged.
What is the magnification factor used for?
It adjusts the image size to match the camera sensor; higher magnification reduces the field of view on the sensor.
