When using our high-magnification lens (SDS-Z) without the auxiliary lens, it is possible to use both coaxial light and ring light simultaneously.
The high-magnification lens (SDS-Z) comes standard with a 1.5x auxiliary lens.
In this case, the working distance is 52 mm.
Due to interference with the coaxial light unit, the ring light can only be mounted at the tip of the lens.
Therefore, in this case, only about 20 mm of working distance can be achieved from the lens tip.
Due to the ring light being too close to the object, a light hollow effect (※) occurs.
(It is not practical in terms of both illuminance and working distance.)
※Hollow effect: When the ring light is too close to the object, the center becomes dark.
When the auxiliary lens is removed, the working distance becomes 95 mm.
Additionally, an LED mounting ring can be attached to the area where the auxiliary lens was removed.
Even when the LED ring light is attached to the tip of the lens, a working distance of approximately 60 mm can be maintained.
However, since the LED mounting ring is attached to the lens tip, the auxiliary lens cannot be installed, so the magnification cannot be changed.
(When using a high-definition camera, the magnification ranges from 55x to 320x. ※Calculated value based on a 17-inch monitor.)
Of course, if the coaxial illumination is not used and the ring light is attached to the body of the lens, the auxiliary lens can be used. (See the picture below)
Even with a coaxial illumination lens, if the light guide port is removed, a ring light can be attached.
If you prefer to switch between coaxial light and ring light instead of using them simultaneously, choosing a coaxial illumination lens allows you to switch between the two as needed.
