Key Features

Wide compatibility

Supports filter sizes from 22.5mm through to 105mm.

Precision construction

Manufactured from black anodised aluminium for durability and optical stability.

Custom sizing

Custom adapters and filter mount configurations are available.

Wide-angle support

Designed to minimise vignetting in wide-angle and short focal length applications.

Standard Filter Mounts

Threaded filter mounts for standard optical filtering applications

Standard filter mounts and retaining rings are manufactured from black anodised aluminium.

Inner and outer threads are manufactured with the same size and pitch, enabling straightforward filter integration.

Filters are stocked from 22.5mm to 62mm, with larger sizes available to order up to 105mm.

Standard Filter Mounts
Mount Size Range Details
Small Sizes M22.5 x P0.5 to M40 x P0.5
Medium Sizes M43 x P0.75 to M62 x P0.75
Large Sizes M67 x P0.75 to M105 x P1.0
Material Black anodised aluminium

Right Angle Adapters

90° viewing for space-constrained environments

Right angle adapters enable 90° optical viewing where installation space is limited.

These rotating adapters feature vibration-resistant locking mechanisms and provide up to 360° adjustment for accurate alignment.

Right Angle Adapters

Slip Mount Adapters

Adapting filters to lenses without filter threads

Slip mount adapters allow standard filters to be mounted onto lenses without threaded filter mounts.

These adapters are individually laser cut to suit the outside diameter of the lens and are ideal for varifocal and wide-angle optics.

Oversized filters can also be integrated to minimise vignetting on short focal length lenses.

Slip Mount Adapters
Adapter Range Details
Lens Front Diameter 10mm to 100mm
Thread Sizes M22.5 x 0.5 to M105 x 1.0
Applications Wide-angle, varifocal and short focal length lenses

Board Camera Adapters

Slip mount adapters for 14mm diameter board camera lenses

These compact filter adapters enable board cameras to operate with ultraviolet, infrared and specialised optical filters.

Precision machined black anodised aluminium construction ensures secure mounting using a single set screw.

Multiple filters can be mounted simultaneously where required.

Board Camera Filter Adapter

C/CS-Mount Filters

Filters mounted directly in front of the camera sensor

These threaded filter mounts screw directly into C- or CS-mount cameras, positioning the filter immediately in front of the sensor.

After installation, the lens threads directly into the camera body, positioning the filter behind the lens.

C/CS-Mount Filters

Step-Up / Step-Down Rings

Adapting filter sizes while minimising vignetting

Step-up rings allow larger filters to be mounted onto lenses with smaller filter threads.

Step-down rings allow smaller filters to be mounted onto lenses with larger filter threads, although this may introduce vignetting.

Sizes are available from 25.5mm to 105mm, with custom sizing available.
