HOZAN Varifocal Lens with Adjustable Focal Length and Working L-600-1236 C-mount Distance.

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. The 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 enables you to observe objects of various sizes at the optimal distance and magnification. Increasing the working distance allows for observation with a wider field of view. Conversely, shortening the working distance enables observation at higher magnifications. You can choose the optimal setting according to your application. Equipped with an aperture function ranging from F2.8 to Close, it allows for a wide range of adjustments to light intensity and depth of field. Because it uses a highly versatile C-mount, it can be attached to and used with various types of cameras and microscopes.
