Apogee AI-FW50 Series Filter Wheels for Alta and Ascent Models
The AI-FW50 series of filter wheels provide large format filtering solutions for the Alta and Ascent series of imaging systems. The FW50 filter wheel currently has two interchangeable filter carousels; A large 7 position 50mm square wheel ideal for the U9000 and U16 imaging systems, and a 9 position 50mm round wheel ideal for any other Alta or Ascent system.
The filter wheel is controlled via USB 2.0. The filter wheel easily adapts to the Alta D2, D7, and D9 bodies, as well as to AP systems.

Apogee AI-AFW30-7R Series Filter Wheels for Ascent Models
The AI-AFW30-7R filter wheel provides a precision photometric filtering solution for many of the Ascent series of imaging systems. The wheel plugs directly into the front of the Ascent camera, using the integrated Ascent Peripheral Interface for power and control. A 2-inch slip fit adapter is available for mounting on telescopes. Coupled with the optional Nikon F-mount lens adapter, the camera and filter wheel can be easily mounted to any F-mount lens, or to any microscope with an Nikon F-mount camera adapter. The AI-AFW30-7R filter wheel was specifically designed as a photometric wheel for advanced astronomy applications. The AI-AFW30-7R filter wheel is not compatible with the larger Ascent A16000. For those requiring larger filters for photometric filter applications, the Optec IFW or Apogee FW50 filter wheels are recommended. Apogee also offers the Astrodon filter sets for this wheel, or the customer can specify alternatives.

Apogee AI-AFW50-5R Series Filter Wheels for Ascent Models
The AI-AFW50-5R filter wheel provides a precision photometric filtering solution for ALL of the Ascent series of imaging systems. The wheel plugs directly into the front of the Ascent camera, using the integrated Ascent Peripheral Interface for power and control. A 2-inch slip fit adapter is available for mounting on telescopes. Coupled with the optional Nikon F-mount lens adapter, the camera and filter wheel can be easily mounted to any F-mount lens, or to any microscope with an Nikon F-mount camera adapter. The AI-AFW50-5R filter wheel was specifically designed as a photometric wheel for advanced astronomy applications. The AI-AFW30-7R filter wheel is perfect for the larger Ascent systems, such as the A9, A8300, A105, A11000, and A16000. Apogee also offers the Astrodon filter sets for this wheel, or the customer can specify alternatives.

Apogee AI-AFW25-4R Series Filter Wheels for Ascent Models
The AI-AFW25-4R filter wheel provides a fast compact filtering solution for many of the Ascent series of imaging systems. The wheel plugs directly into the front of the Ascent camera, using the integrated Ascent Peripheral Interface for power and control. A 2-inch slip fit adapter is available for mounting on telescopes. Coupled with the optional Nikon F-mount lens adapter, the camera and filter wheel can be easily mounted to any F-mount lens, or to any microscope with an Nikon F-mount camera adapter. The AI-AFW25-4R filter wheel was specifially designed as an entry level visual RGB or CMY wheel for astronomy, and with faster transition time between filters for faster image acquisition and for microscopy applications. The AI-AFW25-4R filter wheel is not compatible with the larger Ascent A16000. For those requiring larger filters or photometric filter applications, the Optec IFW or Apogee FW50 filter wheels are recommended. For photometric applications with smaller Ascent CCDs (less then 25mm diag), the AI-AFW30-7R Series filter wheel is recommended. For photometric applications with larger Ascent CCDs (more then 27mm diag), the AI-AFW50-5R Series filter wheel is recommended.

Optec IFW Intelligent Filter Wheel for Alta and Ascent Models
The Optec Intelligent Filter Wheel system offers two configurations not available with the Apogee filter wheels. Their IFW-3 supports a carousel for Optec's 58mm square filters. Their IFW supports a 8-position carousel for 1" filters. There are many options with the Optec filter wheels, including telescope adapters, camera adapters, cable lengths, and PC adapters. Please call for technical details and pricing.
The Optec IFW has the ability to determine the identification (ID) of a particular wheel and apply that wheel ID to a preprogrammed set of filters. The names, not just position numbers of these filters, are read on the eight character display and are also available to the camera operating software via a serial interface using a simple command structure. Up to 5 different filter wheels can have separate IDs and each wheel can have up to 5 filters for a total of 25 identifiable filters.
