Right Angle Camera Adapter
As part of the CVF Trinocular Focusing System (and also available separately), the innovative Right Angle Camera Adapter allows the microscopist to both focus with the CVF focuser, and to attach the 35mm DSLR or other instrument in a comfortable and convenient working position to take the picture. Key features include:

Standard T-Thread Mount. A male t-thread mount on the adapter accepts any standard t-threaded instrument with female M42x.75 threads. The right angle adapter normally includes a t-ring installed for your specific DSLR when ordered with the system.
Standard Trinocular Mount. The Right Angle Adapter fits trinocular tubes of any diameter - 23mm, 25mm, 30mm,30.5mm, and others. The size of the focusing tube spacer is specified when ordering.
