HOZAN Lens Varifocal Lens Freely Adjust Focal Length and Working Distance C-Mount L-600-1236

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. A wide range of focal lengths from 12mm to 36mm equivalent can be adjusted steplessly, allowing you to change the field of view (magnification) while maintaining the working distance. This allows you to observe objects of various sizes at the optimal distance and magnification. By increasing the working distance, observation with a wide viewing angle is possible. On the other hand, by shortening the working distance, observations can be made at higher magnification. You can choose the most suitable settings according to your needs. Equipped with an aperture function from F2.8 to Close, you can adjust the amount of light and depth of field over a wide range. Since it uses a highly versatile C-mount, it can be attached to various types of cameras and microscopes.
