| The working distance of our coaxial illumination microscope (Z500CS) is 52 mm. |  |
|
When a ring light is attached here, the clearance (working space) will be approximately 20 mm. The optimal position for our ring light is approximately 45 to 60 mm. At 20 mm, it causes a hollow effect and results in the area becoming darker instead. With limited clearance, the usability and ease of operation are also compromised. ※ Hollow effect: When the ring light is too close to the object, the center becomes dark. |
 |
| Even when attempting to attach the ring light, this position is obstructed by the coaxial illumination, making it impossible to install. |  |
|
Raising the ring light to this position will interfere with the lens zoom dial. Additionally, the coaxial illumination creates shadows in certain areas. |
 |
| ■ Recommendation for those who wish to use a ring light | |
| By slightly lowering the magnification from 65x–390x to 45x–270x, the working distance can be extended from 52 mm to 95 mm, allowing for the attachment of a ring light. The auxiliary lens at the front of the Z500CS is removed, and a ring light mounting ring is then attached in its place. | |
With this method, the ring light can be installed in the optimal position, allowing for the switching between the ring light and coaxial illumination based on the application, enabling their combined use. |
