C/CS-Mount filters
Step rings
Standard Filter Mounts Each filter is stocked in (22.5mm to 62mm) but larger filters (67mm to 105mm) can be made to order.
Slip mount adapters Should the lens in use not have threads for mounting a filter, are available which attach a regular filter to the front of a lens, or attach a very large filter to accommodate a wide angle lens and prevent vignetting. Slip Mount adapters are individually laser cut to fit the lens' outside diameter
Board camera adapters for 14mm diameter lens This filter adapter enables board cameras to capture where only regular cameras have gone before – into the ultraviolet, infrared and all points in between
C/CS Mounts This threaded mount screws into any C- or CS-mount camera so that the filter is positioned directly in front of the sensor.
Step Rings Used to adapt very large diameter filters to the slip mount

Slip mount adapter      
Slip-mounts allow standard filters to be used on lenses that do not have filter threads eg:  
• Filters for varifocal, wide angle lenses are supplied without filter threads due to a wide angular field-of-view and a strongly convex first lens element
• Using oversized filters to prevent vignetting with adapting filters to all short-focal-length lenses. Step rings are used to adapt very large diameter filters to the slip mount.

Slip mount adapter for 14mm diameter, Board camera lens    

This filter adapter enables board cameras to capture where only regular cameras have gone before – into the ultraviolet, infrared and all points in between. Made of precision machined and anodized aluminum, it attaches securely to the lens with a single set screw making filters very easy to change as the subject or imaging requirements change.

All filters can be sized to fit this tiny adapter: bandpass, longpass, etc. Filters are held in place with a slotted, threaded retaining ring, and there is ample space inside the mount for multiple filters if required.

* All dimensions in mm * Diagram not to scale * Material - black anodized aluminium
C/CS-Mount filters  
This threaded mount screws into any C- or CS-mount camera so the filter is positioned directly in front of the sensor. After installing the filter, the lens is then threaded into the camera and the filter sits immediately behind the lens.

 

Step-Up/Step-Down rings  
Step-up rings allow large filters to be used on lenses with smaller diameter filter threads; the filter will be much larger than the diameter of the lens. Use of step-up rings is often mandatory and routine with shorter focal length or wide angle lenses in order to prevent vignetting.

Step-down adapters allow smaller filters to be used on lenses with filter threads of larger diameter. This may result in vignetting so their use is normally not recommended. Ring sizes cover 25.5 to 105mm and custom sizing is available. Please contact Adept for your size requirements.
