USEFUL GOODS WHEN YOU WANT TO STRETCH YOUR W.D.

If you don’t mind the decrease in magnification, you can increase the working distance (W.D.) by using a 0.5x auxiliary lens.

 

If you are willing to sacrifice magnification, you can use a 0.5x auxiliary lens to increase the W.D.

 

0.5x auxiliary lens for standard lenses TG-0.5   <Example> By attaching a 0.5x auxiliary lens to the TG500PC2, the magnification of 23x~140x is usually reduced to 11x~70x, resulting in an extension of the focal length of 90mm to 160mm.

 

However, doing so may dim the lighting because the LED ring illumination worn on the tip of the lens will be farther away from the subject. In order to compensate for this, it is necessary to adjust the lighting, such as replacing it with a brighter light or removing the diffuser.

There is also a way to change the position of the light by adjusting the angle of the LED, but this can interfere with the purpose of lengthening the W.D. Therefore, we recommend the use of twin-arm lighting (SPF-D2) or LED spot lighting (SPF-FL3).

 

	Even though a 0.5x auxiliary lens is used to increase the working distance, if the illumination is lowered by adjusting the angle of the LED, the W.D. expansion effect will be impaired.
For this reason, it is again recommended to use twin-arm lighting or LED spot lighting.
