FMA 23.2mm Eyepiece to Fixed Microscope Eyepiece Adapter
The FMA series adapters convert a 23.2mm diameter eyepiece tube to a C-mount interface, enabling direct attachment of a microscope camera to a fixed eyepiece.
Product Overview
The FMA series adapters convert a 23.2mm diameter eyepiece tube to a C-mount interface, enabling direct attachment of a microscope camera to a fixed eyepiece. Available in four models with magnifications from 0.37X to 1.00X, each matches a specific sensor size range. The adapter ensures the camera captures the full field of view without vignetting when the sensor is smaller than the available field.

Key Benefits
- Converts a 23.2mm eyepiece tube to C-mount for direct camera mounting
- Available in four models to match sensor sizes from 1/4" to 1"

- Preserves the 18mm field of view when the sensor is smaller than the available field
- Eliminates need for a separate C-mount adapter or optical extension tube
Application Scenarios
- Attaching a digital camera to a fixed eyepiece on a biological or stereo microscope for inspection documentation
- Integrating a microscope camera into a legacy instrument with a 23.2mm eyepiece tube
- Matching a camera sensor size to the available field without image cropping or vignetting
- Upgrading a benchtop microscope with a fixed eyepiece to digital imaging capability
- Using a camera with a 1/2" to 2/3" sensor on a microscope with a 23.2mm eyepiece tube
Who It Is For
- Electronics manufacturers doing PCB and SMD inspection with fixed eyepiece microscopes
- Laboratories upgrading analog microscopes to digital imaging without replacing the body
- Teaching labs adding camera output to fixed eyepiece instruments for group viewing
- Quality control teams needing consistent image capture from fixed-eyepiece microscopes
- Research labs integrating cameras into older microscope models with 23.2mm eyepiece tubes
Problems It Solves
- A fixed eyepiece microscope cannot accept a camera without a proper adapter
- Mismatched sensor size causes vignetting or field cropping when attaching a camera
- Using a generic adapter may introduce optical distortion or incorrect magnification
- Lack of C-mount interface prevents direct camera attachment to a 23.2mm eyepiece tube
- No clear guidance on which adapter matches the sensor size and field of view
Technical Features
- 23.2mm diameter eyepiece tube interface for compatibility with standard microscope eyepieces
- C-mount output for direct connection to microscope cameras
- Magnification options: 0.37X, 0.50X, 0.75X, 1.00X to match sensor size
- Designed for 18mm field of view, ensuring full coverage when sensor is smaller
- No optical correction or lens elements; purely a mechanical adapter

Customization Options
- Select the correct model based on the camera sensor size and desired magnification
- Choose FMA037 for 1/4"~1/3" sensors, FMA050 for 1/2"~2/3", FMA075 for 1/1.8"~1", FMA100 for 1" sensors
- Contact support to confirm compatibility if sensor size or field is unclear
- No custom magnification or size options beyond the four listed models
Comparison With Other Options
| C-mount to 23.2mm eyepiece adapter | This adapter works in reverse: it connects a 23.2mm eyepiece to a C-mount camera, while the reverse is used when attaching a camera to a standard eyepiece tube. |
|---|---|
| C-mount extension tube | An extension tube adds distance but does not change interface; this adapter changes the interface from eyepiece to C-mount without altering optical path length. |
| Generic 23.2mm to C-mount adapter | This model is designed with specific magnification and field matching; generic adapters may not preserve field coverage or introduce optical error. |
Use Guide
- Identify the sensor size of your camera before selecting the adapter model
- Ensure the sensor is smaller than the available 18mm field to avoid vignetting
- Attach the adapter to the 23.2mm eyepiece tube using the screw mechanism
- Connect the camera to the C-mount output; no additional power or signal cables are needed
- Verify image coverage on screen; if the image is cropped, the sensor is larger than the available field

Frequently Asked Questions
Which adapter do I need for a 1/2" sensor?
Use FMA050, which is designed for 1/2"~2/3" sensor sizes.
Can I use this adapter with a 1" sensor?
Yes, use FMA100, which supports 1" sensor size.
What happens if my sensor is larger than 18mm?
The image will be cropped or vignette; the adapter is only suitable when the sensor is smaller than the available 18mm field.
Does the adapter affect magnification?
Yes. The adapter adds magnification: 0.37X, 0.50X, 0.75X, or 1.00X depending on the model.
Is there optical correction in the adapter?
No. The adapter is purely mechanical with no lens elements or optical correction.
Can I use this with a digital microscope?
Only if the digital microscope has a 23.2mm eyepiece tube and a fixed eyepiece that can be accessed for adapter attachment.
